ELECTRICAL DEVICES

摘要

The invention relates to an electrical device for the authentication of a physical object in combination with a first electrical part and a device with NFC capability. The electrical device comprises a second electrical part. The first electrical part can be coupled (can be adhered) to the physical object. The first electrical part and the electrical device are separate elements configured to be disposed in relation to one another and in relation to the NFC device in such a way that, when in use, the first electrical part and the second electrical part are electrically coupled in order to form a resonant circuit having an inductive electrical element and a capacitive electrical element. This resonant circuit is formed such that an inductive coupling occurrs between the NFC device and the inductive electrical element. This inductive coupling occurs in such a way that an NFC communication is brought about between the inductive electrical element and the NFC device.
