ABSTRACT:
An inventory control system uses an electronic tag that keeps an unalterable log of each step in the handling of a controlled item, which may be a flight safety critical aircraft replacement part. The tag is electrically powered via an inductive coupling to a computer with which it communicates, and comprises a non-volatile computer memory element configured so that data may be written into unused portions of it, but so that no existing data can be overwritten or erased. Each tag contains an unalterable secret identification record that is only accessible to a user who has a valid password. As a countermeasure against sophisticated theft attempts involving communicating with the "smart tag" to defeat the security system by learning the password and thereafter altering identification records, etc., the tag permits only a limited number of attempts to read out the secret identification number.
