RFID or Radio Frequency Identification, also called "smart labels", in it's simpliest definition, are tags or intelligent bar codes that can "talk" to a network system. It can give the relevant information or data incorporated on a particular product or object using radio waves. The difference between a bar code and RFID is its simultaneous communication and communication distance capability from the reader. An RFID tag contains at least two parts: First, the chip or integrated circuit that stores and processes information, modulates and demodulates the radio frequency (RF) signal, and other necessary functions; Second is an antenna that receives and transmits the signal into an RFID tag reader. At a basic level, each RFID tag works in the same way: * Data stored within an RFID tag's microchip waits to be read. * The tag's antenna receives electromagnetic energy from an RFID reader's antenna. * Using power from its internal battery or power
