Is RFID a new technique?
RFID has been around for many years now and can solve many of the problems associated with bar codes. Radio waves travel through most non-metallic materials, so they can be ’embedded’ invisibly in packaging or encased in protective plastic for weatherproofing and greater durability. Radiotags / transponders have microchips that can store a unique serial number for every product manufactured around the world as per standards.
