The following product manufacturers are participating in the trial: Gillette, Johnson & Johnson, Kimberly-Clark, Kraft Foods, Nestle Purina PetCare, Procter & Gamble Company and Unilever. Initially a total of 21 products will be included in the test; each Supercenter typically stocks 100,000 products, Wal-Mart said, adding that it is targeting 100% readability of pallet tags through dock doors and 100% readability of case tags on distribution center conveyor belts.
