Normerica, a provider of cat litter and other products for pet dogs and cats, is among the first to use cardboard boxes with UHF Gen 2 RFID inlays embedded in them. In this way, the company can simply encode an RFID chip on each box destined for Wal-Mart Canada, thereby eliminating the step of attaching electronic product code labels to boxes.
To encode the boxes' RFID tags, the company is employing RFID interrogators mounted on custom-designed mobile carts, which can be wheeled to a conveyor where Wal-Mart-bound products are being packed, thereby reducing the cost of building fixed readers at each conveyor.
