Abstract
An electronic seal including a housing, alarm circuitry which when actuated provides an alarm signal, a wire extending from the housing and in electrical communication with the alarm circuitry, a locking element which selectively lockingly engages the wire to the housing, and a switch external to the housing in electrical communication with the locking element which selectively unlocks the locking element to release the wire. There is also provided an electronic seal including a housing including alarm circuitry, the alarm circuitry when actuated providing an alarm signal, a wire extending from the housing and in electrical communication with the alarm circuitry, the wire being attached at a first point and at a second point thereof to the housing, a portion of the wire between the first and second points, called a tying portion, being suitable for tying an object, wherein tampering with the tying portion actuates the alarm circuitry, and an adjustment device for adjusting a length of the tying portion.
