Wal-Mart Launches RFID Milestone: Page 4 of 4

"We can certainly understand and appreciate consumer concern about privacy," Dillman said. She added that the tags do not contain, nor will they collect, any data about consumers, and the company won't have any RFID readers on the stores' main sales floors for "the foreseeable future."

Consumer product manufacturers participating in the trial include The Gillette Co., HP, Johnson & Johnson, Kimberly-Clark, Kraft Foods, Nestle Purina PetCare Co., The Procter & Gamble Co. and Unilever. Products delivered in tagged pallets and cases include paper towels, lotion, cat food, shampoo, feminine hygiene products, laundry detergent, deodorant, shaving cream, soap, toothpaste and peanuts.
