RFID (Radio Frequency Identification) allows an item, for example a library book, to be
tracked and communicated with by radio waves. This technology is similar in concept to a
cell phone. RFID is a broad term for technologies that use radio waves to automatically
identify people or objects. There are several methods of identification, but the most common
is to store a serial number that identifies a person or object, and perhaps other information,
on a microchip that is attached to an antenna (the chip and the antenna together are called
an RFID transponder or an RFID tag). The antenna enables the chip to transmit the
identification information to a reader. The reader converts the radio waves reflected back
from the RFID tag into digital information that can then be passed on to computers that can
make use of it |
