tags or transponders, which transmit electronic product codes (EPCs) and communicate wirelessly to other devices over radio frequency (RF) waves. Attached to physical objects, including the actual product as well as the cartons, pallets and containers in which they are shipped, the tags should uniquely identify the items, as readers communicate with the tag via RF. In a distribution center (DC), once within range of a reader, the data will presumably be captured, accepted, and then executed against by a
