RFID (Radio Frequency Identification) is technology that uses radio waves to transfer data. RFID solutions may considerably increase the efficiency of supply chain logistics. A general difference between RFID and barcodes is that RFID can be read at a greater distance, and under varying lighting conditions. An RFID reader does not need to 'see' the product to be read, and it can read several products at the same time.
An RFID system consists of RFID chips, RFID readers, RFID antennas, software and systems integration.
