What is RFID?

RFID or Radio Frequency Identification is a generic term which refers to a small electronic device consisting of a tiny chip and an antenna. These parts work together to transmit information to a reader using radio waves. The chip is typically capable of carrying 2 kilobytes of data.

Benefits of RFID

  1. Wireless flexibility
  2. High data read rate, reading 100’s or even 1,000’s simultaneously
  3. Extensive battery life (when applicable)
  4. Long-range, surpassing 100’s of feet
  5. Ability to be both read from and written to
  6. Adaption for automation

To retrieve the data stored on a RFID device, you need a reader somewhere in the facility. A typical reader is a device which has one or more antennas. These antennas emit radio waves and then receive signals back from the RFID device. The reader then passes the information in digital form to a computer system. Information can then be stored and manipulated to serve the user’s needs.

Types of RFID

RFID tags come in three general varieties:

  • Passive
  • Active
  • Battery Assisted Passive (BAP)

Passive tags require no internal power source, thus activating only when a reader is nearby to provide power. Semi-passive and active tags require a power source, usually a small battery.
