European supermarket chain Tesco is to start using RFID tags to track the delivery of milk to distribution plants and stores.

The move signals the next phase of Tesco’s RFID plans, which involve using permanent radio tags on “returnable transport items” such as the cages and trolleys used when goods are delivered from distribution centers to the supermarket stores.

This new “unit of delivery” stage follows on from Tesco’s initial trials of radio frequency identification technology. These began in 2003 and involved the use of disposable tags to track the high-value goods most susceptible to being stolen by shoplifters, including razor blades and cell phones.
