Radio Frequency Identification Technology (RFID)
RFID is similar to Bar Code identification. With RFID, the electromagnetic & electrostatic coupling in the RF position of the electromagnetic spectrum is used to transmit signals. An RFID system consist of an antenna and transceiver, which read the radio frequency and transfer the information to a processing device, and a transponder, or a tag, which is an integrated circuit containing the RF circuitry and information to be transmitted.

One of the key differences between RFID and Bar Code technology is RFID eliminates the line-of-sight reading that Bar Coding depends on. Also, RFID scanning can be done at greater distance than the Bar Code scanning.

Manufacturers, suppliers, distributors, logistics providers and retailer clients have been rapidly adopting RFID. Not only to meet trading partner requirements, but to gain greater supply chain visibility and control. They need to increase operational efficiency and improve customer service.
