Abstract
An electronics circuit first portion is entirely within an electronics module housing, sensing and transmitting a tamper condition of a normally locked bolt. The bolt comprises a second portion of the electronics circuit. The seal electronics circuit first portion comprises a seal monitoring, tracking and communications system. The bolt passes through the module housing and is secured with a locking device external the module such that the module is reusable when the bolt is severed. The bolt and module housing include a cooperative contamination sealing arrangement for sealing the bolt to the housing. The electronics circuit first portion includes RFID tamper detection circuitry, GPS, Wi Fi and cell phone communication and tracking technologies. The cell phone technology tracks the seal using cell phone towers and Wi Fi access points and communicates the seal tracked position and seal status data to a cell phone communications center.
