  • Electronic tag
    Patent number: 12170013
    Abstract: An electronic tag can be secured to a body of a person. The electronic tag has an antenna which transmits or receives an electromagnetic signal. An inductive proximity sensor determines a proximity of a metallic object to the electronic tag, based on electromagnetic coupling between the inductive proximity sensor and the metallic object. The inductive proximity sensor determines, based on the proximity being below a proximity threshold, that a metallic object is attenuating the electromagnetic signal transmitted or received by the antenna.
