paroneayea writes "There's a lot about RFID tags in the news today. Wal-Mart is officially beginning to use RFID tags on its merchandise. We've heard about Wal-Mart's plans to introduce RFID tags in the past, but this is the first time that this is actually being put into use. To quote the article: 'Wal-Mart is billing this as a trial, but Simon Langford, Wal-Mart's manager of RFID strategies, told RFID Journal that this is the beginning of the company's planned roll-out of EPC (Electronic Product Code) technology.' Meanwhile, California does something right for a change and introduces a bill that will limit the use of RFID tags in stores and libraries to protect the privacy of customers. IBM, which plans to be a major manufacturer of RFID tags, bashes critics of RFID tags as 'anti-retail.'"
