Embodiment Construction

[0050] Within the scope of this description, the terms "connected", "connected" and "coupled" are used to describe both direct connection and indirect connection, direct or indirect connection and direct or indirect coupling. Identical or similar elements are provided with the same reference symbols in the figures, as far as this is expedient.

[0051] The chip card may be a smart card or an integrated circuit card (ICC) in different embodiments. The chip card can be manipulated and / or read out, for example, by means of a card reader and / or terminal. Chip cards are suitable, for example, for initiating and / or carrying out authorization processes, e.g. for releasing information and / or for releasing access to closed areas, and / or for initiating and / or carrying out payment processes, e.g. on the ATM.

[0052] figure 1 A chip card 10 is shown. The smart card 10 has a card body 12 . The card body 12 can comprise plastic, for example. For example, card body 12 may have one, tw...

Abstract

The card (10) has an electronic circuit (14), and a coupling element (18) moved in mechanical manner with respect to an antenna (16). Electromagnetic coupling of the electronic circuit with the antenna depends on position of the coupling element. The electronic circuit comprises a reel, and the electromagnetic coupling of the electronic circuit with the antenna is managed through the reel. The coupling element is placed in order to be moved, so that a zone of the coupling element is placed outside the reel and the antenna in a position of the coupling element. Independent claims are also included for the following: (1) a method for utilizing a smart card (2) a method for manufacturing a smart card.

Description

technical field [0001] The invention relates, for example, to a chip card for the contactless execution of authorization and / or payment processes, a method for operating a chip card and a method for producing a chip card. Background technique [0002] Currently, contactless chip cards are frequently used for contactless authorization, authentication, authentication or payment processes. In this contactless approach, for example, a trade-off can be made between safety and comfort. Especially if no additional security functions are used (PIN input, fingerprint, etc.) and / or no so-called "intention announcements (Willensbekundung)" are issued, the use can be very comfortable. For example, the process can be designed in such a way that a chip card, for example in a wallet, does not have to be removed once from a pocket, for example a purse, trouser pocket and / or wallet. However, simple attacks can be carried out in order to steal from the holder of the chip card electronically...
