Abstract: Communication device (T1) comprising—An antenna (A1) and physical circuitry (PHY) for receiving a poll command (PC) from a second communication device (T2).—A plurality of entities (D1, D2, D3 . . . Dn) emulating NFC devices,—An arrangement for deciding, for each entity of said plurality of entities, if a response should be sent and if so sending a response (LF1, LF2, LF3 . . . LFn) to said second communication device (T2), containing information related to the respective NFC device.

Abstract: A method in a signal generating unit, SGU, generates a signal to be used in a Near-Field Communication, NFC, reader. The SGU is configured to communicate with an NFC controller unit, NFC-CU, and with an NFC-Wired Interface unit, NFC-WIU. The NFC-CU and the SGU are included in an NFC device, and the NFC-WIU is connected to the NFC device. The SGU receives a first signal that includes data encoding information indicating a first unique identifier supported by the NFC-CU, from the NFC-CU, and a second signal that includes data encoding information indicating a second unique identifier supported by the NFC-WIU, from the NFC-WIU. The SGU generates a third signal to be used in the NFC reader to generate a collision sequence, based on the first signal and the second signal. An SGU configured to perform the method, and a NFC device that includes the SGU are also provided.

Abstract: The invention concerns a security chip of a communication device, comprising: a near field communication interface (37), a first processing unit (42), a first non volatile storage capability (45), adapted to store first information related to near field communication, and connected to be accessed, from outside the security chip, through said near field communication interface (37), under the control of said first processing unit (42), wherein it also comprises a second non volatile storage capability (48), adapted to store second information related to near field communication different from said first information, and connected to be accessed, from outside the security chip, independently from said first processing unit (42).

Abstract: A method in a signal generating unit (422) for generating a signal to be used in a Near-Field Communication, NFC, reader (200) is provided. The signal generating unit (422) is comprised in an NFC device (400) and configured to communicate with an NFC controller unit (421) and an NFC-Wired Interface unit (300), The NFC controller unit (421) is comprised in the NFC device (400). The NFC-Wired interface unit (300) is connected to the NFC device (400). The signal generating unit (422) receives a first signal from the NFC controller unit (421), which first signal comprises data encoding information indicating a first unique identifier that is supported by the NFC controller unit (421). Also, the signal generating unit (422) receives a second signal from the NFC-Wired Interface unit (300), which second signal comprises data encoding information indicating a second unique identifier that is supported by the NFC-Wired Interface unit (300).
