Future looks rosier for RFID
Tiny chips touted as a wonder technology that could transform shopping and manufacturing are slowly making headway, but the cost of producing them is preventing mass usage.
Radio Frequency Identification (RFID) was invented more than 50 years ago but has so far failed to live up to its promise to connect everyday things through a wireless network and make it possible, in theory, to track every item ever produced.
Computer scientists dub RFID "The Internet of Things," in which anything from shampoo bottles to marathon runners can be tracked using radio tags. Criticism from some camps is that the technology can lead to an unacceptable invasion of privacy.
