ELECTRONIC DEVICE, CONTROLLER AND CONTROL METHOD FOR NFC

An electronic device for near field communication (NFC) includes a processor including one or more applications and a controller controlling NFC communication between a reader/writer device and the processor. The controller includes a communication unit that exchanges communication between the external reader/writer device and the processor. A parser parses communication exchanged between the reader/writer device and the processor. The parser is configured to detect a predetermined setting of a response code within an authentication response sent by the processor in response to an authentication request received from the reader/writer device, the predetermined setting indicating that an application of the processing unit is in an authenticated state. A further controller controls the communication unit not to respond to an anti-collision request received from the reader/writer device and/or not to forward an anti-collision request to the processor if the anti-collision request is directed to an application in an authenticated state.
