Wal-Mart plans to spend $3 billion over the next several years on a new inventory tracking technology that uses radio-frequency signals to keep tabs on merchandise, sources familiar with the project said.
The system is based on a technology known as radio frequency identification (RFID), a new breed of computer network designed to track the location of everyday objects, such as razors and shoes, by embedding them with special microchips. Wal-Mart has enlisted its top 100 merchandise suppliers to participate in the high-profile project, one of the first and largest of its kind in the retail industry.
