Abstract

A method is provided for interaction of a portable data carrier with an end device. The data carrier comprises a transducer arrangement having at least one or a set of capacitive transducer elements which are arranged on or in the data carrier at defined positions in relation to the geometry of the data carrier, at least one contactless interface, and a dedicated energy supply. The end device comprises a capacitive display screen having a touch-sensitive display, wherein the data carrier generates via the capacitive transducer elements signals which, when the data carrier is placed onto the display screen, are picked up by the display screen of the end device and evaluated as input signals through the end device.
