RFID Applications and Solutions: Manufacturing Lines
Manufacturers can track and record in-process assembly information into the RFID tag as an item progresses along the line. For example, as features are added to a personal computer assembly, they could be recorded on the tag. In this case, the tag would keep a current "inventory" of the PC's contents. The tag information could later be read to produce a shipping list and invoice. The tag could also remain with the item for later use by field personnel during installation and maintenance.
