DHL is rolling out the RFID system to help its customers comply with Wal-Mart's mandate that its suppliers use RFID technology.

Wal-Mart offers RFID update

Wal-Mart continues to update its RFID initiatives, adding new uses for the technology and getting more suppliers and partners to comply with its mandates.

The Bentonville, Ark.-based retailer implemented its RFID system in January 2005 after completing pilots at distribution centers in Dallas, said Carolyn Walton, vice president of information systems.

Sitting on a panel at the RFID World conference here late last month, Walton said the number of Wal-Mart suppliers using RFID technology has more than tripled since the effort began. More than 300 suppliers now feed RFID-tagged goods to 500 Wal-Mart facilities, she said.
