What is RFID?

Radio Frequency Identification. A method of uniquely identifying items by transmitting and receiving electromagnetic (radio) waves. RFID uses electromagnetic fields to automatically identify tags attached to objects. A radio transponder is a tiny device that emits and receives radio signals. It also has a transmitter and receiver that uses the radio frequencies to read tags. The system can identify any type of tag, including bar codes and barcodes. To use RFID, you need a transmitter and receiver.

RFID is an electronic identification system that consists of two components – a tag and a reader. An RFID tag contains an antenna and microchip that communicates with an RFID interrogator. The interrogator emits a radio signal and then transmits the read results to a computer program. These components enable RFID to track inventory and identify items. Unlike barcodes, RFID is a permanent solution, meaning that it won’t wear out and can be used again.
