<p>A safety sealing device includes a support. An electronic safety circuit is glued to one face of the support. The electronic safety circuit includes a winding of fine wire connected to an electronic component. The electronic component is activated and interrogated by outside checking means via the winding, which acts as an antenna. The electronic component may be coded so that it responds to the interrogation with its code. The safety sealing device may further comprise differentiated gluing means. When attempting to tamper with the support to which the safety circuit has been glued in order to unseal a receiving article, the attempt at ungluing or a tearing causes a break in the continuity of the electronic circuit. As a result, the electronic component no longer responds to an interrogation with its code, thus assuredly indicating that the safety sealing device has been tampered with.</p> |
