To understand how RFID innovations, speed up productivity, our team of experts offers answers to your most frequently asked questions or RFID FAQs:

1. What is RFID?

RFID belongs to a group of Automatic Identification & Data Collection (AIDC) technologies that help computers identify objects. The goal of AIDC is to reduce human errors and increase efficiency—Employees are free to perform more valuable duties than manually entering data into a computer.

RFID tags and barcode labels are both AIDC technologies. However, unlike standard barcode labels, RFID tags don’t rely on a line-of-sight visual scan for transmitting data and don’t require a scanner to “see” a barcode to read it. Instead, an RFID tag acts as a transponder, transmitting data by radio waves to a reader. The reader then converts the radio waves into digital information that can be viewed, analyzed, and stored on a computer.

2. How does RFID work?

There are just two components to a passive RFID system, consisting of the tag and the reader. The tag contains an integrated circuit with embedded data along with an antenna that transmits and receives signals. The reader features a transceiver, or interrogator, that transmits an encoded signal that activates the tag. The tag then converts the received radio signal into usable power to respond back to the reader. In this way, the RFID reader functions as a two-way radio transmitter-receiver.

3. What’s the difference between active and passive RFID tags?

When RFID tags are placed on assets, they allow you to find a “needle in a haystack”. Attach tags to assets that are frequently misplaced or are difficult to locate. Motion sensors embedded within active tags will then notify you when an object is moved.

The traditional RFID system utilizes passive tags that collect electromagnetic energy from a reader antenna, but they cannot emit energy on their own. Because they need to be placed relatively close to readers, the read range can be as short as 6 inches. Installing an ultrahigh-frequency (UHF) transponder can increase the read range of up to 20 feet, but this is only in the free air (when the tags are not attached to objects).

These small RFID tags are often attached to small units, and they are best used on lower cost assets within restricted movement patterns.

By contrast, active RFID tags rely on battery power to activate their internal transponder to push the signal to an antenna within its read zone. This gives them a much longer range than passive tags of 300 feet or more. Therefore, active tags enable easy tracking of highly valued assets with variable or unpredictable movements. Since assets with active RFID tags can be tracked across a larger area than passive tags, use them across warehouses and throughout your company’s workspace floor.

Here at ID Integration, we searched for the most reliable and efficient state-of-the-art technology to handle real-time tracking of movements while cutting costs to our clients. We found a solution that is available at nearly half the price of passive RFID systems, and no antennas and infrastructure are necessary—Only the gateway device is required at installation. V-Tag™ Active RFID tags, from InfinID Technologies, seemed like the perfect solution. But we weren't ready to offer them to our clients without vetting them out for ourselves.

We first ran several successful pilot programs for tracking tools and work-in-process in the aerospace and government sectors using V-Tag™ Active RFID location tracking system. We were so impressed with the results that we teamed up with InfinID, the makers of V-Tags™, to offer them to our commercial customers in all business sectors, from military and government to hospitals, general manufacturing, and MRO (Maintenance, Repair & Operations) industries.

The reusable V-Tags™, about the size of a box of Tic Tacs, “talk” to each other to create an ad hoc mesh network, which can enable tracking of items to up to a half mile. When coupled with AssetWorx!™ Active RFID software, the movement of tagged assets are seen in real time, appearing on a virtual map of your facility. Every time an asset is moved, the map refreshes on your computer desktop, tablet, or smartphone screen. Quick installation, plus low cost tags (as little as $35 each) make V-Tag™ Active RFID technology the popular solution for locating assets for any business sector application.

4. Many companies boast about the read range of their RFID systems. In reality, how much range can you get?

The answer to this question depends upon where you place the RFID tag and/or where the tagged item is stored. Much of the popular read range hype is a myth, because the physics of radio frequency are unchangeable, and many variables must be taken into account.

For instance, is the tag affixed to metal? This may change the read range potential, because metal mounted tags don’t read as far as those for non-metal tags.

As another example, we conducted a test at our ID Integration office. First, we placed an RFID tag on the front of a label printer device. Next, we placed an RFID tag on the back of the device. Surprisingly, we experienced a better read range when the tag was placed on the backside of the device. Here’s why: Our building has metal studs inside the walls and the RF signal bounced backwards and then forwards, causing the signal to amplify.

As an experienced system integrator, we understand the many variables involved with read range and can offer multiple solutions—even hybrid solutions—to fit your unique needs. Reach out to our RFID consultants, and we’ll take your environmental variables into account for a customized system approach. Feel free to call us at 425-438-2533 to talk with one of our RFID experts.

5. Can both passive and active RFID systems be combined, along with standard barcode tags?

Passive RFID tags are best applied to tracking specific parts as in serialized asset tracking, where assets pass through checkpoints in a work in process environment. Active tags are best used for getting a quick picture of the location of assets for audits and tracking. And standard barcode labels (for military applications or for FDA applications, for instance) may be the best choice when using line of sight verification with a scanner. Your industry may demand the use of all of these solutions for smart manufacturing production efficiency.

For example, assets that are frequently moving will benefit most from RFID location tracking. However, stationary assets that rarely move (furniture, large equipment in shop, etc.) are easily located with asset tracking labels featuring both RFID and barcodes. Inventory audits using integrated RFID labels can be as simple as scanning for locations of RFID tracked assets without requiring any line-of-sight or physically scanning the integrated RFID labels on stationary equipment with a barcode scanner.

Combining these solutions makes sense from a production efficiency standpoint, but the roadblock is analyzing disparate data. Our partners at InfinID have the perfect solution—AssetWorx!™ Software. The same software that works seamlessly with V-Tags™ to produce a real-time software map of asset movements is capable of much more—AssetWorx! Software is instrumental for creating a hybrid RFID tracking database.
