The UK retailer Marks & Spencer has announced the expansion of its item-level RFID tagging trial to additional locations and items. Included in the items will be multiple sized items (that are difficult for stores to keep stocked on the floor) including women’s underwear. Need we be concerned about unintended reading of our undergarments? One writer thinks not, citing “As in current Marks & Spencer trials, items will be tagged with five-inch-long paper labels, a form factor also known as “hang tags.” … failure to remove the 5 inch long paper hang tags from underwear would cause considerable discomfort to the wearer.”
