RFID

RFID stands for Radio Frequency IDentification. It typically applies to a technology that uses radio waves to automatically identify people or objects. While there are various ways to identify, the most common is to store a serial number that represents a person or object identity and possibly other information, on a microchip that is attached to an antenna. Collectively the microchip and antenna represent a RFID transponder or an RFID tag. The antenna gives the chip ability to transmit identity information to a RFID reader. Then the RFID reader converts the radio waves into digital information that can then be passed to the computer for usage. RFID has been around since the 1970s.
