What Makes an RFID Tags Different Than Barcodes?

Tracking inventory via barcodes can be tedious and might even lead to inaccuracies. Each barcode must be scanned, but only after properly aligning it with the optical scanner. An easier, more accurate, and more efficient method is through the use of RFID tags.

RFID stands for “radio-frequency identification,” and it refers to the technology where digital data is encoded into RFID tags, and then captured and read through radio waves. Keeping track of inventory and assets can now be done without line of sight, and can even range from just a couple centimeters to over 20 meters.

Only three components are needed in an RFID system: an RFID tag, an RFID reader, and an antenna. The RFID tag contains an integrated circuit and an antenna, which transmit data to the RFID reader. The RFID reader then converts radio waves to more useful data, and that data can then be collected and transferred through different computer systems or databases.

Looking at the electromagnetic spectrum, radio waves fall below both visible light and infrared waves. Radio waves fit in the range between as few as 3 hertz  and as high as 1 gigahertz. Within that range fit three different usable frequencies for RFID tagging: low frequency (125-134 kilohertz), high frequency (13.56 megahertz), and ultra-high frequency (300-3000 megahertz). 

Low frequency RFID tags have a short range, reaching as far as 10 centimeters. You will probably find one of these applications in your pocket, within your car’s key fob. Other uses include access controls and even animal tracking. RFID tags in the low frequency all adhere to global standards, and work well near liquids and metals.

High frequency RFID tags have an increased range of up to 30 centimeters. These also follow global standards and have larger memory options when compared to low frequency uses. These days you can find high frequency tags in library books, personal ID cards, and in NFC applications like your smartphone or credit card.

Incorporating RFID tags into your business applications might take time and money, but you should inspect the advantages. First, consider the return on investment when deploying a new system. If both the application and cost feasibilities fit for your work environment, then it might be time to take that first step toward progress.
