Why is RFID better than bar-coding?
RFID isn’t ‘better’ than bar-coding, it is different, however the technology does give many advantages: No direct line of sight required Because tags use radio, they can be embedded into objects, objects can even be living animals! Infact many pets in the UK now contain an RFID ‘Microchip’ so that they can be returned if lost. Many tags can be scanned at once Unlike a pallet of bar-coded goods which must each be scanned individually, a pallet of goods using RFID tags can be scanned in one go simply by passing through a suitable reader. Tags can be read from and written to A barcode is printed and cannot have further information added to it, however an RFID tag can be written to at multiple instances. This means that products passing through many locations could have date/time information added at each stage.
