16. A method for releasing a transaction between a portable data carrier and an end device, comprising the steps:
-
a) bringing the portable data carrier into an electromagnetic field generated by the end device and drawing power by the data carrier from the electromagnetic field for the power supply of the data carrier, b) exciting the portable data carrier by mechanical oscillation, c) capturing the mechanical oscillation in the portable data carrier by means of an acceleration sensor, d) evaluating an output signal of the acceleration sensor with regard to characteristic properties of the mechanical oscillation, e) releasing the transaction by the portable data carrier as soon as a characteristic property of the oscillation has been recognized through the evaluation of the output signal. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27)

28. A portable data carrier for transferring data with an end device, wherein the data carrier has a release apparatus, said release apparatus comprising:
-
an acceleration sensor arranged to enable mechanical oscillations of the data carrier to be ascertainable by the acceleration sensor and to generate acceleration sensor output signals, and an evaluation unit that evaluates the acceleration sensor output signals and ascertains the mechanical oscillations, a data transfer between portable data carrier and end device being releasable upon the evaluation unit generating a release signal by reason of a mechanical-oscillation characteristic required for the release.

29. A module for releasing a transaction with an end device, comprising:
-
an acceleration sensor for capturing a mechanical oscillation, an evaluation unit for evaluating the captured mechanical oscillation, wherein the mechanical oscillation is evaluated with regard to characteristic properties, a comparing unit for comparing the characteristic properties of the mechanical oscillation of the evaluation unit with a target value of the characteristic properties, wherein the comparing unit releases the transaction when the target value of the characteristic property is exceeded, and the comparing unit does not release the transaction when the target value of the characteristic property is undershot.
