About RFID

  • RFID stands for Radio Frequency IDentification
  • RFID uses radio waves to identify or locate an item
  • RFID will gradu
  • RFID does all that barcodes do (and much more), without the limitations of barcodes technology

In a more general sense, RFID is a technology, which provides unprecedented visibility to the supply chain and makes possible product identification and traceability. There are several methods of identification through RFID, but the most common is to store a serial number that identifies an 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.
