NFC device and communication method |
| 摘要 |
According to an aspect of the invention, an NFC device for communicating with an NFC reader is conceived, the NFC device comprising an NFC integrated circuit, an antenna unit connected to said NFC integrated circuit, and 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. |

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; wherein the detuning circuit does not switch the antenna unit off during the periodic detuning; wherein the detuning circuit is arranged to receive a detuning signal from a processing unit, and wherein the detuning circuit is arranged to detune the antenna unit in response to receiving said detuning signal. |
