Wal-Mart has announced that it will begin inserting Radio Frequency Identification (RFID) chips into some of its men's clothing, including jeans, underwear, and socks, starting August 1. The retailer has stated that its goal is to expand the use of the tags to its other merchandise as well. Previously RFID tags have only been used in larger packages for warehouse and distribution use, but this will be the first time the tags are used in the stores for individual products that will be taken home by consumers. The tags will remain readable from a short range even after they are removed from the store. For more information, see EPIC RFID Systems.
