ABSTRACT:
A single use security padlock-style lock for sea containers, bonded warehouses, trailers and other storage areas where security is necessary. The lock has an electronic timepiece which displays the time and date in a tamper-resistant case. A shackle is extended through the hasp or closure of the area to be secured. When the shackle is engaged in the lock body, the timepiece display is interrupted providing an indication of the time the area was secured. Each case carries a unique identification number.
