This white paper the EPC Tag Data standard. If you have been asked recently to mark you cases and pallets with RFID labels, you are probably sending those products to Wal-Mart! Compliance is nothing new for you, many retailers have asked you to put a special label or identifier on your finished goods. RFID could be a bit more of a challenge because of the technology but with the right supplier you can achieve compliance with minimal disruption to your operations.
The current Wal-Mart initiative is for product at the carton and pallet level only. In some instances, the case is indeed the item. Therefore, the item will need an RFID tag.
