Abstract
The invention relates to a near field magnetically coupled contactless tag, comprising a substrate comprising a rupture zone; a master microcircuit arranged on the substrate on one side of the rupture zone, and configured to be interrogated by a near-field reader; a slave microcircuit arranged on the substrate on the other side of the rupture zone; and a sacrificial link connecting the two microcircuits, wherein the two microcircuits are configured to negotiate mutual authentication through the sacrificial link.
