<p>An antitheft electronic seal for tracking a container comprises: a casing (1), a locking cord (4), a locking cord connection receptacle (5) provided on the outer wall of the casing, a radio-frequency chip (2) and a radio-frequency antenna (3) provided within the casing, a locking cord jack (51) provided within the locking cord connection receptacle, and a metal insert (52) embedded in the locking cord connection receptacle and in contact with the locking cord. The radio-frequency antenna has two portions (31, 32), wherein two ends of the first portion (31) are connected to a first end (41) of the locking cord and the radio-frequency chip respectively, and the two ends of the second portion (32) are connected to the radio-frequency chip and the insert respectively. In the present invention, once the locking cord is broken, the information inside the radio-frequency chip becomes unreadable and the electronic seal becomes invalid, which facilitates the determination of the location of the cargo's theft and the prompt search for the cargo; and at the same time, the task of locking the object to be locked up can be accomplished by simply threading the locking cord therethrough, giving the invention a wide range of applications.</p> |
