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). Then, the signal generating unit (422) generates a third signal based on the first and the second signal, which third signal is to be used in the NFC reader (200) to generate a collision sequence. A signal generating unit (422) for generating a signal to be used in an NFC reader (200) and an NFC device (400) comprising a signal generating unit (422) is also provided.

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.
