Marks and Spencer is pushing on with the rollout of RFID tagging. It confirmed on Tuesday that it will start using RFID tags in another 80 UK stores from next spring, having run trials in 42 outlets.

The tags will be used on items where there are a wide range of different sizes, such as men's suits and women's trousers and skirts.

An M&S spokeswoman told our colleagues on silicon.com that it could be rolled out to other clothing types from autumn 2007.

RFID can help retailers to run an efficient supply chain, but M&S may also encounter a backlash. In the US, CASPIAN has protested about companies such as Wal-Mart, which has been trialling RFID for some time.
