Companies like RFID because of all the advantages electronic tracking can have when used in appropriate applications [1]. The biggest problem has been the cost of tags--it has been assumed that the cost is such that they only make sense on products that cost $100 or more. However, Staples has begun an experiment with its vendors on RFID tags that follow the product through shipping and inventory control, but are then removed at the point of sale for re-use. The re-usability should let the five-to eight-dollar tags pay for themselves by the end of their anticipated five-year lifespan. With RFID tags getting smaller [2] and becoming easier to embed in even the smallest products [3], re-usability may well be the future of RFID at companies ranging from Staples to Wal-Mart [4].
