The "Tamper Loop" stickers are equipped with the new NXP NTAG 213 TT chip type. In case of an open detection wire, the NTAG 213 TT (Tamper Tag) permanently stores this event.  In the event of tampering, the data programmed within the Tag can be changed (redirected to a different URL or to different memory sheets).

These stickers are ideal in contexts where it is important to verify that a product or a machine has not been tampered. In fact, their particular structure is designed to change in case of removal or tampering.
