RFID cargo/storage container tamper seal
First Claim
1. An RFID cargo/storage container tamper seal applicable to Customs safety cargo container inspection systems equipped with RFID readers, comprising:
- a main insulating body;
a helix-shaped antenna installed in the main insulating body and comprising a probe;
a metal ring accommodated in the main insulating body and having a C-shaped ring inlaid around its inner surface;
a locking rod comprised of a hollow metal pillar, wherein a first portion of the locking rod is in a cone shape and is encapsulated by an insulating material and a second portion thereof uncovered by the insulating material has a ring-shaped groove disposed around its peripheral surfaces; and
a circuit module comprised of an RFID chip, an impedance module, a conductive elastic piece and a probe sheath, the circuit module being packaged in the hollow portion of the locking rod, one end of the RFID chip being connected with the conductive elastic piece while the other end of the RFID chip is electrically connected to one end of the impedance module, and the other end of the impedance module being electrically connected to the probe sheath via the conductive material plated on the circuit module.

Abstract
An RFID cargo/storage container tamper seal consisting of a main insulating body, a locking rod and a circuit module is disclosed. The main insulating body has a helix-shaped antenna and a ring-shaped metal ring, wherein the inner surface of the metal ring has a C-shaped ring inlaid therein, and the antenna has an antenna probe extending and protruding from the metal ring. A first portion of the locking rod is cone-shaped and encapsulated by an insulating material, and a second portion thereof exposed from the insulating material has a ring-shaped groove disposed around its peripheral surfaces. The circuit module has an RFID chip embedded therein and is packaged inside the rod portion, thereby allowing an RFID reader to read electromagnetic waves/signals containing identification codes transmitted from the RFID chip of the RFID tamper seal via the antenna.
