NFC DEVICE AND COMMUNICATION METHOD
First Claim
1. An NFC device for communicating with an NFC reader, the NFC device comprising an NFC integrated circuit, an antenna unit connected to said NFC integrated circuit, wherein the NFC device further comprises a detuning circuit, wherein the detuning circuit is arranged to cause a periodic detuning of the antenna unit to a detuned state, such that data transmission between the NFC device and the NFC reader may take place periodically while the NFC device and the NFC reader remain within communication range of each other.
