Radio frequency identification (RFID) technology is not being used to its full potential, according to research published this week.The 2005 Consumer Packaging Report argues that RFID has so far only scratched the surface of its capabilities, with use limited to internal tracking projects. Privacy concerns are hindering the full exploitation of RFID's potential to improve consumer safety & service radically, says the research. Rexam, the consumer packaging manufacturer that commissioned the research, says RFID will make industries that are testing the technology more accountable to their customers, & will improve consumer safety. "We believe that, far from being a threat to consumer privacy, RFID presents a wealth of opportunities for retailers & brand owners to meet customer needs & concerns", Felix Helander, Business Intelligence Director at Rexam said.
