WHAT IS RFID?

RFID (Radio Frequency Identification) is a generic term for technologies that use radio waves to automatically identify distant objects. In its simplest form, an RFID tag is a microchip that is attached to a minuscule antenna. Data stored on the chip is transmitted wirelessly through the antenna to a scanning device that operates on the same frequency as the RFID tag. The scanning device converts the radio waves reflected back from the tag into digital information that can then be passed on to the computer network.
