RFID – What You Need To Know

RFID, or Radio Frequency Identification, is a technology we’re sure you’ve heard of by now. After all, it’s ability to track item location and data provide endless benefits:

  • Increased supply chain efficiency
  • Reduced human errors in inventory
  • Eliminated cost of replacing lost or stolen items
  • Elevated security
  • And more….

It has numerous applications:

Companies and organizations have increasingly adopted this technology for the above benefits, and have additionally realized the advantage it provides in reacting to unforeseen events such as COVID-19. Subsequently, using RFID or another tracking technology is essential to remaining competitive in today’s market.

But where do you start?

We’ve been in the industry a long time and provide a basic overview of RFID below so that you can begin your journey towards efficiency, lower operation costs, security and more. To see how RFID compares to other tracking technologies, see this article.

Radio Frequency Types

RFID functions on radio wave frequencies, which are measured within frequency bands: low frequency, high frequency, ultra-high frequency (such as RAIN RFID) and super-high frequency.  These terms refer to the wavelengths of the frequency – low frequency has longer wavelengths, which increase and shorten as the frequency gets higher.

Frequencies determine the strength and distance of the signal. Low frequency usually has a weaker signal and a shorter read distance but is less affected by disruptors to radio frequencies (such as liquid or metals). This is important for environments that may require RFID tags to interact with these substances. Higher frequencies promise a stronger signal and one that reads at a farther distance but is more sensitive to disruption from various materials1.

This table compares frequency bands and the technology used in each one:

Predominant RFID

Within the world of RFID material handling there are two predominate technologies used; HF and UHF.  UHF is the most predominate of the two due to its long-read ranges.  HF is used when short read ranges are desirable (such as use cases requiring isolation) or when the laws of physics prohibit the use of UHF (such as tracking of items that contain large quantities of water).

For this article, we will focus on the UHF frequency band.

RFID System Components

RFID systems are always comprised of two primary components: a transponder (tag/label) that goes on the item being tracked and the interrogator (reader). These components work together to store data about an item’s location, transmit that data and ultimately distill that data into usable information via a software application. Software apps, such as ItemAware, allow users to look up an item, see its location, and add additional data about the item (such as maintenance information, item history and much more).


Components of RFID System

RFID Tags: Passive, Semi-Active, Active

RFID tags are placed on every item that is going to be tracked. Different types and sizes of RFID tags determine versatility for different environments, infrastructures, and cost thresholds. A main distinction between tags is the method by which power is supplied to them – determining if they are passive or active.

First, let’s break down the types of RFID tags and how they work:

Passive RFID Tags are the simplest RFID tag, only containing an integrated circuit and an antenna. They do not transmit signals to readers, but rather engage when a reader sends a signal to the antenna. This is done through backscatter technology – without signals from the reader, the tag remains inactive. If the tag is located outside the reader’s range, the tag won’t have sufficient energy to send information to the reader. Because the tag does not contain a battery, they last indefinitely.

Semi-Active RFID Tags (also called semi-passive or battery-assisted passive (BAP) tags) communicate the same way that passive tags do – by receiving a signal from the reader. However, the semi-active tag circuitry is powered by a battery. The battery enables a longer read range than passive tags, but not as long as an active tag.

Active RFID Tags have their own energy supply, e.g. a battery or a solar cell, which is used to provide power to the chip and generate the RF signal for transmitting data to the reader.  Given that the strong electromagnetic field needed to power a passive tag is not necessary, the distance from the tag to reader can be significantly increased, yielding an increased coverage area for each reader. The battery typically lasts around 2-5 years before being replaced. Active tags can offer a longer read range – up to 1000ft / 304m – and are often used on items that need to be tracked over long distances.

Tags can be used on multiple items throughout their existence.

Tag Cost

The price of RFID tags considers the durability, frequency, volume of tags needed, etc. This means that there is not a straightforward price to share for each tag; however, passive tags are less costly than semi-active and active tags, and prices generally fall in these ranges (NOTE: prices do change based on the market, inflation, demand, etc.):

  • Active: Active RFID tags start around $25 / tag upwards of $100 tag.
  • Semi-Active: usually cost around $10-$25 per tag.
  • Passive: Passive RFID tags cost anywhere from $0.07 to $0.50 each

It is often assumed that passive RFID is the cheapest option on the market – and, when looking at tag price alone, this is true – but there are many factors that go into a final cost. Which means that what makes up your cheapest option depends on your requirements and the factors we continue to explore in the rest of this article.

Tag Sizes and Types

RFID tags come in a wide range of sizes. Active tags are generally larger because they have more components, while passive RFID tags can be as small as a grain of rice.2 Our engineers are continually engineering solutions that allow tags to affix to items properly so that they do not obstruct function and avoid being destroyed when an item is used. A recent example includes inserting a tag into a divot on a chainsaw for tool tracking, so that the chainsaw is tracked without risking damage to the tag during use. Another example is tamper-evident tags that are placed on weapons boxes. If the box is tampered with, the tag alerts users (like a security officer), increasing security and minimizing theft.

Since use cases are broad and tag options are numerous, it is best to talk to a professional to determine which tag is right for your situation.

RFID Readers

Readers are essential for the RFID system as they send signals to tags and collect tag data. They fall into two main categories: fixed and mobile.

Fixed readers allow users to track items as they pass through chokepoints (such as entryways, stairwells, etc.). When an item passes through a chokepoint, the data is collected by the reader and communicates to the user that the item has moved from one location to the next. Fixed readers are the most expensive category of readers, but they also have the highest read range. A subset of fixed readers is an integrated reader which is often used in visible areas of indoor locations, because of its sleeker design.3

Mobile readers come in a variety of forms from a Mobile Computing Device that has an onboard computer, to a Sled that can fit on a person’s mobile phone and transfer data through Bluetooth or auxiliary connection. Users walk through inventory and scan to read the tags in that location with handheld readers. These readers are usually more cost-effective than fixed readers and are especially effective when searching for a specific item in an exact location.3 Once again, the right reader is determined by use case.

RFID Antennas

Antennas are another essential component of an RFID system, as they create the communication between the reader and the tag. Antennas are placed on both the reader (to send the signal to the tags) and on the tags that receive the signal (in turn transmitting the information that the chip is storing).

The signal strength between a tag and reader can be determined by the antennas, their size, polarity, and the degree of wave expansion as it leaves the antenna.4

Compliance ItemAware RFID

Sarbanes-Oxley Compliance and RFID

RFID can help businesses pass audits and fulfill requirements imposed by the Sarbanes-Oxley act (SOX) – a law that has had drastic operational and financial impacts on U.S. companies.  


Nearly twenty years ago, in 2002, the Sarbanes-Oxley Act was created to hold publicly traded companies accountable for their financial reporting.

This came after some of the U.S.’s largest companies were exposed for financial scandal. Unethical business practices and falsified financial statements landed these companies in bankruptcy – evaporating employee’s retirement plans and crumbling investor trust in corporations.1

What is Sarbanes-Oxley?

SOX implemented rigorous controls for financial reporting and auditing. This was done to ensure the accuracy of corporate disclosures, with a hefty criminal charge for non-compliance.

With the creation of SOX, companies quickly made investments in controls that would help them pass audits. However, many continue to underestimate the massive undertaking of accounting for assets and rely on a large workforce and static spreadsheets for reporting.

RFID can revolutionize this process – eliminating human error, showing asset status in real-time and being a reliable source for data.

RFID’s Role in Sarbanes-Oxley Compliance

RFID is an efficient, accessible technology that collects data from items (think medical supplies, tools, IT assets and anything in between) and provides real-time reports with item status, history, and location.

RFID can play a critical role in SOX compliance by:

  • Increasing Reporting Accuracy:
    • SOX Requirement: A company’s financial statements must be accurate to the best of the executive officer’s and chief financial officer’s knowledge.2
    • RFID Benefit: Assets play a role on a company’s financial statement – and an inaccurate count can lead to errors in reporting. Manual asset tracking is prone to human error and risks this accuracy. Automating this process with RFID diminishes that possibility as readers collect, organize, and report the data. This ensures that everything is accounted for – which can reduce loss rates by as much as 99%.
  • Disclosing in Real-Time:
    • SOX Requirement: Section 409 of the Sarbanes-Oxley act requires that material changes in a company’s financial condition or operations are required to disclose the information on an almost real-time basis (within 48 hours).3
    • RFID Benefit: Automatic data can capture supplies’ real-time information as readers read the RFID tags. This can be done with continual updates or by passive readers that scan an item any time it passes by (such as entering a new location). Software receives this information and organizes it, then feeds it to the user. Users can even get automated alerts when an item’s information changes.
  • Providing Traceable Source Data:
    • SOX Requirement: any source data in financial reports must be traceable and any changes documented.4
    • RFID: Data pulled from RFID readers is easily viewed. All changes to any assets are recorded and kept with the pertaining asset. This allows users to trace all information and keep it updated as changes occur.

Other Benefits of RFID

RFID’s features directly correlate to the SOX requirements mentioned above – but it has other ways it supports this as well:

  • Simple Reporting: RFID makes running reports incredibly easy as data is continuously updated and ready to be pulled at any time. Users can enter the parameters and get up-to-date information within minutes, rather than waiting for a manual count or referencing a previous report.
  • ERP Integration: ERP systems are often employed to help with SOX compliance. RFID software, such as ItemAware, can easily integrate with these systems making it easier to share and pull information.


Ensuring that your company is meeting all requirements to Sarbanes-Oxley is crucial, and RFID can make that process easier.

RFID RTLS Uncategorized

RTLS Technology Comparison

You’re thinking about implementing a Real-Time Locating System (RTLS), but you don’t know which technology would best suit your needs.

Lucky for you, there are plenty to choose from… and enough options to construct the optimal solution.

Let’s dive right in.

Definition: Real-Time Locating System (RTLS)

A real-time locating system is technology, hardware and software that determine a person or item’s location. They then collect data for analysis. The use cases for this spread across a wide range of industries, from construction sites and warehouses to office buildings and hospitals. RTLS have saved organizations millions of dollars in saved time, efficiency, and reduction of “lost item” costs. They also enable industries to react quickly to unexpected challenges.

RTLS technology varies in price and function. Each have advantages and disadvantages depending on the user’s needs. While performing a site survey is the best way to determine the right technology for your use case, we have compared them below for easy research.

Types of RTLS Technology

RFID (Radio Frequency Identification)

RFID is a tracking system that uses electromagnetic or radiofrequency devices to communicate with a tag (transponder). These tags are attached to items and send location data to readers (interrogators). The readers feed that information into software which reads and analyzes the data that is transmitted.

RFID is broken down into categories, measured by their frequency band: low frequency, high frequency, ultra-high frequency, and super high frequency.

This includes passive and active RFID, as well as cellular, Wi-Fi, Bluetooth (Low Energy) and Ultra-Wide Band (UWB). The following table outlines the ranges for each one.

Chart comparing different real-time locating system technology.

(UHF = Ultra-High Frequency, SHF = Super-High Frequency)

An important distinction between RFID systems is the method by which power is supplied to the transponder – making it either active or passive RFID.

Active RFID

Active tags have their own energy supply, such as a battery or a solar cell. This is used to provide power to the chip and generate the radio frequency signal for transmitting data to the reader.

  • Use Case Examples:
    • Supply chain logistics
    • Container tracking
  • Advantages:
    • Large coverage area for each reader (up to 300ft (91 m) using technology built on commercial standard, up to 1500ft (457m) using technology built on proprietary standard)
    • Long read range
    • Global standards
    • Less susceptible to radiofrequency interference
    • Strong data signal
  • Disadvantages:
    • Large tags (in some cases this does not matter)
    • Tag beacons still need to be in range of the reader to report
    • Must consider RF physics in deployment
    • Proprietary solution (if you need up to 1500ft read range) will lock you into a single supplier 
    • Needs replaced every 2-5 years depending on the settings
    • Not printable onsite*

*RFID tags have space for a printed label that can include barcodes and human readable information.

Passive RFID (RAIN)

Passive RFID (RAIN) labels do not have a power supply. The electromagnetic field produced by the reader’s transmitter is enough to initiate response from the tag and pick up the data. However, the tag must be within the reader’s range and will only emit data when read (unlike an active tag that is always ‘on’).

  • Use Case Examples:
    • Supply chain logistics
    • Retail
    • Toll collection
    • Parking systems
    • Access controls
    • Asset management
    • Industrial automation
  • Advantages:
    • Lower initial cost
    • Global standards
    • Proven technology
    • Multiple hardware and tag providers
    • Hardware and tags developed for all environments
    • Indefinite lifetime
    • Smaller tags
  • Disadvantages:
    • Weaker data signal strength
    • Must select proper tag based on application.
    • Susceptible to RF interference must be consider in deployment
    • Printable onsite

Bluetooth Low Energy (BLE)

In 1999, standards were created around ‘Bluetooth’ – a continuous point-to-point data connection for streaming data in computers, cell phones and other devices. It has become widely adopted for wireless earbuds, keyboards, speakers, etc.

Bluetooth Low Energy (BLE) was introduced in 2010 with the release of Bluetooth 4.0. This defined the protocols for communicating short bursts of data from point to point or broadcasting data to multiple devices. BLE uses less energy than previous standards and enables device configurations that can run for several years on a tiny coin-cell battery.  The introduction of Bluetooth 5.0 in 2016 increased data bandwidth and range requirements while optimizing battery life. This gives developers more choice in range, speed, and broadcasting capability. BLE mesh networking specifications were released in 2017, which define networks that allow multiple devices to communicate reliably at the same time.

BLE devices operating in the broadcast mode are commonly referred to as BLE beacons. In RTLS terms, this would be the “tag”. These broadcast a message providing identity, configuration, and data from associated sensors (such as temperature, light exposure, vibration, etc.). The radiofrequency signal is used to estimate the location of the device and transfer of data.

Bluetooth beacons can be manufactured quickly and for a lower cost than competing technologies because of the simplicity of the technology.

  • Use Case Examples
    • Access control
    • Toll collection
    • Asset tracking
    • Industrial automation
  • Advantages
    • Lower cost than traditional RTLS tags
    • Long read ranges
    • Wide variety of beacons (in both physical form and battery capacities)
    • Some beacons can accept firmware updates or reconfiguration via networked management software (i.e., updates and configuration instructions can be installed remotely without handling every device)
    • Broad vendor base
    • Location accuracy can be tailored to meet business requirements (this is determined by the hardware chosen that supports various location techniques)
    • Increased accuracy at any point, while maintaining the currently deployed “tag” base (by changing the receiver or sensor devices)
  • Disadvantages
    • Some beacons require physical interaction to update configuration or firmware (a technician must visit the physical location of the device)
    • Still maturing supplier base
    • Tag battery replacement cost
    • Proprietary solutions will lock you into a single supplier


Wi-Fi is a wireless network that allows devices to connect to the internet. A small device known as a wireless transmitter, or hub, is required. The hub receives information from the internet via your home broadband connection. This transmitter (often referred to as a Wireless Access Point, or WAP) then converts this information into radio waves and emits it. This effectively creates a small, local, area around itself. Within this area, your devices can receive the transmitted radio signals. This area is often termed a Wireless Local Area Network, or WLAN for short.

Wi-Fi location systems use the same standards as Wi-Fi based wireless local area networks (LANs). To provide tracking of assets, a powered Wi-Fi tag utilizes the same location services used for tracking phones, computers, and other powered devices.

  • Use Case Examples
    • Access control
    • Toll collection
    • Asset tracking
    • Industrial automation
  • Advantages
    • Wi-Fi tags allow customer to leverage existing Wi-Fi network, saving on infrastructure costs for a location system
    • Long read ranges
    • Multiple hardware and tag providers
    • Improved location accuracy with proprietary solutions*
  • Disadvantages
    • Tag or battery replacement cost
    • Proprietary solution will lock users into a single supplier
    • Location accuracy can be diminished by radiofrequency multipath errors and daily environmental variation. (Typical asset placement errors are within 5-10 meters depending on the specific location methods utilized).
    • The radio frequency band utilized by Wi-Fi is popular and prone to congestion. Adding a Wi-Fi based tracking system onto an already congested environment could result in poor performance.

*Proprietary Solution: A hardware or software product (or combination of products) and services that is tied to a specific vendor, to the exclusion of all other vendors.


Barcodes are machine-readable codes in the form of numbers and a pattern of parallel lines of varying widths. Originally done in 1D, these tags are now done in 2D as well, enabling the capture of more complex data which can be visually represented with various geometric patterns.

Regarding location tracking, information is encoded in one or more barcodes and placed on the object. This is used to provide automated data capture of item identity and location.  Information can be derived in the device and passed to the system with a hand-held imager at a workstation or choke point reading a single symbol.  Other techniques rely on image capture and analysis by additional software. This allows users to capture data from multiple assets in an area such as a warehouse storage rack.  Data is then passed to the application software.

  • Use Case Examples
    • Retail
    • Shipping and receiving
    • Asset management
    • Mobile POS
  •  Advantages
    • Universally adopted
    • Labels can be printed on site
    • Labels are attached easily
    • Advanced symbology allows robust data encoding (if a portion of the symbol is damaged data can still be retrieved)
    • Advanced symbology is scalable and can be printed in various sizes if an image can be acquired for analysis (very small with image access by magnification or very large with extended read distances)
    • No battery replacement cost
  • Disadvantages
    • Requires disciplined asset handling:
      • Assets must be processed, transported, and placed in storage to provide line of sight access from the reader to the label.
      • If an item is moved to a new location by other than defined processes and the label is not visible, the location of that item cannot be determined
    • Physical Label damage can prevent data capture (if a single line is damaged or added to a traditional barcode the encoded data cannot be retrieved)
    • Limited or prohibited usage in classified areas due to image capture capability
    • Wide area analysis may require illumination of the area to enable data capture
    • Variations in printer quality or handwriting impact data accuracy and / or ability to read data 

Cellular GPS

Cellular is currently used to provide communications across wide areas.  Cellular companies are leveraging their existing networks to support the Internet of Things (IoT) with data plans.

Where location accuracy is required, triangulation with cell towers can be used to determine a transmitter’s location (similar to GPS tracking). But when greater location accuracy is required, embedded GPS can be combined with cellular backhaul capabilities. The cellular GPS system has the capacity to serve tens of thousands of subscribers in a major metropolitan area and is highly successful for outdoor environments that need tracking solutions.

  • Use Case Examples
    • Fleet management
    • Container tracking
    • Asset management
  • Advantages
    • Leverages existing cellular network; does not require dedicated infrastructure installed and maintained to collect data from tags.
    • Ability to connect to a power source or be battery powered
    • Rapidly deployable
    • Easy installation and deployment
    • Over-the-air programable
    • Over-the-air serviceability status updates
    • Accelerometer available for motion sensing
    • Ability to pass live sensor data
    • Ability to pass telematics
  • Disadvantages
    • Requires a data plan
    • Battery replacement
    • Battery can be rapidly depleted depending on programing and device settings
    • Location accuracy inside building
    • Some providers require you to use their service

Ultra-Wideband (UWB)

Ultra-Wideband (UWB) is a type of RFID technology that uses an extremely low power level and super high transmitting frequency to provide tag information for location-based solutions. A UWB real-time locating system can track thousands of tags precisely, in a large area like a warehouse, or a single tag in a small coverage zone like a doorway.

UWB systems communicate over long distances with less degradation in performance. The reader can focus on a specific area to interrogate the tags, so UWB systems provide greater location accuracy than other systems.

  • Use Case Examples
    • Sports (NFL, Hockey)
    • Manufacturing work in progress
    • Personnel tracking/safety
  • Advantages
    • UWB transmits at such a low power level and across such a wide frequency range that it does not affect other wireless technologies such as Wi-Fi, Bluetooth, UHF, or handheld passive readers
    • High performance around metallic surfaces
    • Resistant to signal jamming and tampering
    • Good penetration properties
    • Omni directional antennas
    • Long read ranges
    • Location accuracy
    • No spectrum licensing required
    • No limitation to worldwide operations
  • Disadvantages
    • Proprietary solution
    • No standard
    • Tag or battery replacement cost

RFID Asset Tracking Systems: Features to Look For

RFID asset tracking and management systems should have certain features that meet tracking challenges. Continue reading for six specific attributes to look for when deciding which system to choose. 

With costs coming down and the technology making great advances, more and more industries and businesses, large and small, are investing in RFID as a cost-effective solution to meet their asset tracking challenges. One study estimates the global market for RFID technologies will be $38 billion by 2021, more than double the market today. If you are considering using RFID, below are six characteristics that a good RFID asset tracking and management system should have.

RFID Tracking System Characteristics to Look For

  1. Easily Integrated. No manager wants the pain and cost of completely replacing existing infrastructure. If you can’t integrate a system easily, few of the decision-makers will get on board for implementation. An RFID system does involve purchasing additional equipment and software, but the right asset tracking system will also work together with existing systems, meaning modification rather than replacement.
  1. Growth Options. Your asset management system should easily expand as your company grows. Make sure the software is flexible and future-proof.
  1. Customizable. “One-size-fits-all” is not a desirable feature in asset management systems – every business need and situation is unique. The solution needs to adapt to your specific needs and budget.
  1. Asset Visibility. Improved technology reduces some of the limitations of RFID. The system should track in any environment, indoor or outdoor, and track moving assets if required. The best solution provides real-time tracking with accurate, up-to-date reporting.
  1. Secure. A secure RFID system is one that offers safeguards. Tracking assets makes it easier to monitor compliance and security issues, but an effective system will monitor and sends alerts, and then create reports for auditing purposes.
  1. Cost Effective. This means more than ROI. An RFID asset tracking system may improve safety, which goes beyond positive or negative ROI. But your asset tracking solution should easily install and be maintainable, and it should not require intensive training or additional staff.

RFID Tracking System Alternative Options

When analyzing the cost of these systems, you will need to consider whether you need passive or active RFID. Active tags are more expensive, but by being battery-powered and always “on”, they are better for tracking real-time locations and moving assets. Active tags are also read from further away than passive tags. Passive tags depend on the reader for power but are used in many instances and are a more economical solution for some applications.

Conclusion – Consider Aware Innovations

Knowing the basics to look for is important, but most companies don’t have the in-house resources to install and commission an RFID asset tracking system efficiently and effectively. The additional expense of having expert guidance will more than pay for itself through a faster deployment with less risk.  You start seeing the advantages of the RFID system – and the resulting positive ROI – much sooner.

Aware Innovations has the consulting and integration services to help you make the right decisions. For more information on how an RFID asset tracking and management system can help your business be more efficient and productive, contact us today.


RFID Tracking

Radio-Frequency Identification (RFID) tracking is indispensable for thousands of businesses worldwide. There are several benefits to using RFID to automatically identify and keep track of assets and inventory. Continue reading to learn more about this tracking option and the benefits it has. 

What is RFID Tracking?

Radio-Frequency Identification (RFID) tracking is the use of RFID tags to track assets or inventory. These tags are attached to items that an organization wants to collect data on. Once the tag is placed, an RFID scanner scans them, and data is captured and stored.

RFID Tracking Benefits:

Time and Cost Savings

Perhaps the primary benefit of using RFID technology to track your assets is the time and cost savings. According to a comprehensive study by RAMP RFID, an organization with approximately 100,000 assets can save up to $150,000 by moving to RFID-based asset tracking technology.

Unlike traditional barcode scanning and manual tracking, RFID technology uses radio and electromagnetic signals to track truckloads of information. For example, for an organization to check inventory on a service van, they just need to turn on the RFID reader and information about the inventory loaded on that specific van will be transmitted instantly. Receiving this information instantly saves the company time that would have been spent manually tracking the inventory.

Another case study showed that a client company was able to dwindle its inventory costs by a whopping 60% after it moved to an IoT-based RFID solution made by GenPact.

Avoiding ‘Lost Sales’ and Theft

Companies around the world suffer massive losses amid ‘lost sales’ which may be a result of the lack of RFID tracking technology. Human error gives the opportunity to misplace physical items. By placing tiny radio transponders or tags, companies can track their assets and items constantly.

Tracking constantly, without the vulnerability of human error, could result in literally thousands of dollars in savings annually. Walmart made RFID technology mandatory in its warehouses and supply stores in 2005 when they realized the cost savings and efficiency that resulted. American Apparel was able to get 100% visibility over its assets after introducing an Ultra-High Frequency (UHR) RFID solution in its stores. The company also managed to track and recover 1,500 lost items due to RFID technology.

Standardized and Scalable

RFID has become a standardized way of tracking assets and inventory. In 2008, the Financial Services Technology Consortium (FSTC) was founded by big companies like Bank of America, Wells Fargo, Citibank, and other tech companies. The purpose of the consortium was to standardize the RFID tracking technology of assets. This initiative made RFID scalable and secure.

Passive RFID technology is used for tracking physical assets. It doesn’t matter what kind of assets a business wants to track. Everything from IT assets like computers, smartphones and tablets to healthcare assets like medical equipment and patients.
