Abstract
RFID tags of very small size are embedded in products or composed of products in a manufacturing process. The system employs different read and write modes to enable auto-tracking of material, some assembly, assembly and component items through various stages of the manufacturing process. As each item passes special predetermined points in the manufacturing process, the embedded tag is activated and placed in track mode. The tag transmits its ID and a track count representing the number of stations passed. The tag's track count is incremented and the updated track count is stored in non-volatile memory in the tag. The tags can be programmed so that once the count exceeds a predetermined count, a status bit is set in the tag's memory indicating that the item has been completely through the manufacturing process. Thus, the system can determine whether an item or product has been completed. After manufacture the same RFID tag can be used for tracking, inventory and item authentication.
