Embodiment Construction

[0020] FIG. 1 shows an exemplary embodiment of a smart card 1 embodied according to the invention in a schematic sectional illustration. The illustration is not strictly limited to a section, but also shows relatively offset components of the smart card 1 . Hence no hatching is used. Not shown to scale for clarity. A plan view of the associated smart card 1 is shown in FIG. 2 , which also shows the components arranged in the smart card 1 .

[0021] The smart card 1 has a card body 2 in which a chip module 11 is embedded and electrically conductively connected to an electrical connection element 12 . The chip module 11 contains a microcontroller 13 in which, for example, the application software of the chip card 1 is implemented. With regard to its dimensions, the card body 2 is preferably designed according to the ISO / IEC 7810 standard and is made of five plastic foils 15 in the exemplary embodiment shown. As a material for the plastic film 15, PVC is suitable, for example...

Abstract

The invention relates to a portable data carrier (1) comprising an electronic circuit (13) for storing and / or processing data and an oscillating circuit (29, 30, 31) for contactless communication and / or power transmission. The inventive portable data carrier (1) is characterized in that an actuator (30, 31) which can be influenced externally is provided for changing the resonant frequency (fres) of the oscillating circuit (29, 30, 31) between a first frequency range and a second frequency range.

Description

technical field [0001] The invention relates to a portable data carrier and a method for operating the portable data carrier. Background technique [0002] It is known in portable data carriers such as chip cards to disable or enable contactless communication between the portable data carrier and eg a corresponding reading device depending on the state of a mechanical switch. For this purpose, the mechanical switch breaks the electrical connection or establishes such an electrical connection. However, such mechanical switches are relatively difficult to manufacture and are also subject to wear and tear. [0003] As an alternative, it is known to select the operating mode of the chip card as a function of the detected state. Thus, if the smart card receives an external voltage via the contact surfaces of the chip module, contactless communication is inhibited, for example, by an internal control mechanism. Contents of the invention [0004] The technical problem to be so...
