Auto manufactures are among the leading users of RFID technology today. Most cars have an RFID reader in the steering column and a transponder in the key. If the ID in the key doesn’t match the number the reader is looking for, the car won’t stop. This system has greatly reduced auto theft. Auto companies also use RFID to track work-in-process, perfect just-in-time manufacturing, improve shipping accuracy, and manage inventory and warrantee information.
