An electronic locking device secures a shipping container and includes a housing, two arms, a sensing circuit, and electronics. The pair of arms extend from the housing and couple to the hasp. The arms transition between locked and unlocked configurations relative to the hasp, with one or both of the arms pivoting relative to the other. A bolt seal locks the arms in the locked configuration. The sensing circuit, which includes sensing contacts, is in a “closed” state or “open” state depending on whether the arms are in the locked or unlocked configuration. The electronics record and report the state of the sensing circuit, thereby indicating whether the arms are locked or unlocked. |
