Cheap, Printed RFID
New RFID tags with circuitry deposited by simple printing technologies could finally make it cost effective to tag low-value products on retail shelves. The printing process eliminates the need for expensive optical lithography and reduces the consumption of energy and toxic materials, cutting costs: the tags cost less than half as much as existing ones. Mobile phones with built-in RFID scanners could let consumers access information about tagged products, or even pay for them without waiting in line.
