Clipping the wings for privacy

BIGGISH BLUE has developed an RFID tag which has a limited range.

According to Associated Press, the short range tag is designed to sooth the fears of punters who are fed up with having their privacy violated by their clothing labels.

Big Blue boffins have developed the technology along with Marnlen Management which will produce labels with RFID circuitry stretched across perforated paper.

This enables you to tear the tag's radio antenna from the chip that stores product information and cut its broadcast range down to a few inches.

The big idea is that it will become impossible to use the RFID chip to track people, although its ability to act as a good security device in shops will be limited.
