Abstract

The invention relates to an electronic device (10) and a method for data communication with such an electronic device. The electronic device combines, on the one hand, a Near Field Communication (NFC) interface, including an antenna and a circuit for generating a modulated electromagnetic wave, and on the other hand a user interface including a touch-sensitive display configured to present an object relating to a communication action executable by means of the NFC interface. A control unit connected to the NFC interface and the user interface, is configured to trigger the NFC interface to execute the communication action responsive to simultaneous detection of the presented object being touched and the NFC interface being in communicative connection with a second NFC interface of a second device.

Claims
