What is RFID

Hospitals and pharmacies will be adding radio frequency identification (RFID) tags in the years ahead to curb drug counterfeiting. What is RFID? According to the Association for Automatic Identification and Mobility (AIM), a basic radio frequency identification, or RFID, system consists of three components: an antenna or coil, a transceiver (with decoder), and a transponder, which is also called an RF tag and is electronically programmed with unique information.
