Abstract

A method of conducting two-way communication between a first NFC enabled device and a second NFC enabled device. The method includes transmitting a write command from the first NFC enabled device to the second NFC enabled device. A silent mode of the second NFC enabled device, in which the presence of the second NFC enabled device is hidden from the first NFC enabled device, is then activated. While the silent mode is activated, the second NFC enabled device processes the write command and writes a response in a memory of the second NFC enabled device. The silent mode is then deactivated, which triggers the first NFC enabled device to read the response in the memory of the second NFC enabled device.

Dependent claims

A method of conducting two-way communication between a first NFC enabled device and a second NFC enabled device, the method comprising:

placing the first NFC enabled device and the second NFC enabled device in proximity;
transmitting a first message from the first NFC enabled device to the second NFC enabled device;
activating a silent mode of the second NFC enabled device after receipt of the first message;
using the second NFC enabled device to process the first message and write a second message in a memory of the second NFC enabled device;
deactivating the silent mode of the second NFC enabled device;
and
using the first NFC enabled device to read the second message in the memory of the second NFC enabled device;
wherein the presence of the second NFC enabled device is hidden from the first NFC enabled device when the second NFC enabled device is in the silent mode.
