ANTI-COUNTERFEITING TAG MAINTAINING A FUNCTIONALITY AFTER USE

摘要

The invention relates to an anti-counterfeiting tag with near-field magnetic coupling, including a control microcircuit (14) designed such as to implement a basic function and a cryptographic function (CCP); a sacrificial conductive track (12-1, 12-2) arranged across a sacrificial area (18) of the tag; and a circuit for detecting the continuity of the sacrificial track, interacting with the microcircuit such as to implement the basic function without implementing the cryptographic function when the sacrificial track is broken.
