A system for verifying that parts are properly assembled. A radio
frequency identification (RFID) tag is connected to one of the parts that
has an antenna loop. The antenna loop has two spaced contacts that may be
bridged by a shorting bar on the other one of the parts. When the parts
are properly assembled and the shorting bar bridges the contacts, the
RFID tag is enabled to communicate a coded signal to a receiver thereby
determining that the parts are assembled.
