UK retailers have been urged to act over privacy concerns surrounding radio frequency identification technology or risk its growth being stifled by consumer opposition.
Analyst group GartnerG2 said claims by consumer groups such as Liberty do not reflect the facts about the electronic tracking technology, which is gaining popularity among UK retailers including Tesco, Marks & Spencer and Woolworths.
Liberty has set up a unit to monitor the use of RFID tags by UK retailers, after claiming the technology will allow corporations to "control every aspect of our lives".
"Supermarket executives would love to be able to track every item of clothing we bought. It would enable them to build up customer profiles, which they would use for marketing campaigns," said Shami Chakrabarti, director of Liberty.
"Some customers will be comfortable with this, others will consider it a gross infringement of privacy. The important point is that the technology is too powerful to be unregulated. It cannot be right that corporate giants should be allowed to experiment when and where they want without consumers having any say in what is happening."
John Davison, head of retail research at G2, said retailers were letting groups such as Liberty and US consumer watchdog Caspian dominate the RFID debate.
"Some of the claims we are seeing about RFID are more science fiction than science fact," he said. "But if the retail companies do not move immediately to rebut them, consumer concerns over privacy infringement will frustrate the implementation of the technology."
Davison said that to win support for RFID implementations, retailers should:
