Here are some pictures of a Marks & Spencer RFID tagged Intelligent Label TM being tested on men's suits, shirts and ties at their High Wycombe store
M&S have produced some leaflets explaining something about the RFID tags to their customers, for which one has to hunt around for in the High Wycombe store. This is only a slight improvement over Tesco who try to keep their customers in ignorance.
The paper label RFID tags are removable i.e. a separate label on the ties and suits, or on the shirt wrapping, rather than the Texas Instruments type RFID tags designed to be embedded in clothing and capable of withstanding laundry processes.
Note the "Please retain this label for refund and exchange" printed on the label

There are, in fact no RFID readers in evidence in the High Wycombe store men's clothing department, which is relatively small, with probably only a couple of hundred tagged shirts, suits and ties.
It therefore does seem that M&S have been influenced by consumer privacy group pressure to modify their original RFID clothing tag deployment plans.
It also means, presumably, that these RFID tag labels cannot be "killed" or disabled at the checkout.
