What is RFID? - EPC-RFIDEPC-RFID

 

What is RFID?

Radio-Frequency Identification (RFID) is the use of radio waves to read and capture information stored on a tag attached to an object.  A tag can be read from up to several feet away and does not need to be within direct line-of-sight of the reader to be tracked. 

How does a RFID system work?

A RFID system is made up of two parts: a tag or label and a reader. RFID tags or labels are embedded with a transmitter and a receiver. The RFID component on the tags have two parts: a microchip that stores and processes information, and an antenna to receive and transmit a signal. The tag contains the specific...
