A test is under way to trial the use of computer chip tagging in the supply chain. The Boston based Auto ID-Centre is conducting the trials in Tulsa, Oklahoma, and will involve both distribution centres and stores, including a Wal-Mart and Sam's Club. The eight month long field test will be conducted in two phases, the first tracking pallets, and in the second, individual cases of products. They will be embedded with a chip containing an electronic product code which will be picked up by scanners throughout the supply chain and decoded and tracked by computers. Organisations participating in the tests include Gillette, P&G, Unilever, Kraft Foods, Coca-Cola and Johnson and Johnson. A spokesman said: "If these technologies can be proven in the field, they have the potential to significantly improve supply chain management. In the end, we believe this technology, fully implemented, could help slash billions of dollars of cost from the supply chain." {{NEWS }}
