These wireless tags know what’s in the box
Wireless is everywhere these days. Wireless networks surround us, our phones run on wireless technology and connecting devices with cables seems to be a thing of the past. One of the applications of wireless technology is making it easier for objects to be traced and tracked. Radio Frequency Identification (or RFID) tags are being used to track visitors in theme parks, for building access control and for the management of inventory at retailers. Executives from retailers and technology firms have gathered this week at the EPCglobal Conference in Baltimore to discuss the implementation of RFID technology. RFID chips are passive and consist of a circuit and micro-antenna, where information in the chip can be retrieved by a computer sending a radio signal across a large area. Walmart’s deadline for the implementation of RFID for its Top 100 suppliers is 1 January 2005. The world’s largest retailer hopes that, by using electronic pallet, crate and stock tracking, the company will have higher levels of efficiency and reduce theft. One of the more controversial uses for RFID is the European Central Bank’s proposal that RFID tags be embedded in its currency, the Euro.
