What is RFID and How Does It Work?

RFID, or Radio Frequency Identification, is a data collection method that uses a reader to locate and track special tags or labels attached to an item, similar to a bar code system. Instead of collecting laser light reflections off printed bar code labels, RFID uses low wattage power radio frequencies to read from and write to the tags. By using radio signals, RFID eliminates the need for human intervention and a direct line of sight to the tag in order to read it. RFID readers can simultaneously read and write to hundreds of tags within their read field.

Advantages of Using RFID Technology Instead of Traditional Barcodes:

  • Eliminates Line of Sight
    • RFID eliminates the need to position the laser of a scanner across the entire barcode, allowing it to be used when the tag is not in direct view of the scanner.
  • User Intervention
    • RFID readers can be installed to read all the time. Whether they’re installed by doorways, garage entrances or in open areas on manufacturing floors, assets can be read as they are moved.
  • Speed
    • One RFID handheld can count hundreds of assets in the same time it takes for a single barcode scan.
  • Authenticity/Anti-counterfeit Technology
    • RFID tags have a chip-specific ID value, which eliminates the possibility of improperly duplicated tags or copied ID values.
