An electronic circuit senses and transmits a tamper condition of a bolt seal locked with a locking device external the module on a side of the module opposite the bolt head. The module is reusable intact when the bolt/locking device, which is conventional, is opened. In various embodiments, a tang type metal/plastic or plastic tamper indicative seal may be attached through a hole in the bolt tip region that has a narrowed diameter tip or attached in a one way clutch action on the tip, or which mates in a bolt groove at the bolt tip region and/or a conventional tamper evident seal is attached to the surface of the bolt shank at the bolt tip region in a clutch action. Different bolt embodiments comprise non-electrically conductive or electrically conductive plastic or steel shanks with juxtaposed electrical conductors along the shank connected to external conductors formed by coatings or axially spaced cylindrical sleeves forming contact regions which engage the circuitry contacts inside the module.
