Embodiment Construction

[0029] In the context of the aforementioned US patent 7898422, the NFC device becomes silent once the bottle has been opened. However, the user wishes to review the information again, for example, to share it with a friend, or to visit the manufacturer's website to order a new bottle.

[0030] Tags of the type described in US Patent Application 2005-0012616 do not differentiate between the sealed or open status of the container in the information returned by the tag. Indeed, the information returned is the same regardless of the sacrifice of the antenna, as long as the tag reader can present the tag in its antenna-less mode.

[0031] The type of dual tag described in the aforementioned US Patent Application 2007-0210173 requires two separate NFC circuits and two different steps for attaching the tag to an object for protection, which increases manufacturing costs. Also, each NFC circuit independently maintains its full functionality when interrogated by a tag reader.

Abstract

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.

Description

technical field [0001] The present invention relates to near-field magnetically coupled contactless identification devices, such as NFC, ISO 14443 or ISO 15693 devices, and more particularly to anti-counterfeit contactless devices for ensuring the authenticity of the contents of a bottle. Background technique [0002] US patent 7898422 describes an anti-counterfeit NFC device integrated in a wine bottle cork. The device was configured such that insertion of the corkscrew damaged the antenna or control microcircuitry. [0003] When the device is complete, it can be interrogated remotely via an NFC reader to retrieve the information on the product, and also confirm the authenticity of the information. When the cork has been removed, the NFC device is damaged, so the cork can no longer be used to authenticate the contents of a new bottle. [0004] For example, US Patent Application 2005-0012616 discloses an RFID tag with a sacrificial antenna designed to be destroyed upon ope...
