Abstract: Near-field communications (NFC) with NFC reader devices are facilitated. In accordance with one or more embodiments, an apparatus includes a NFC circuit that wirelessly communicates with different types of local NFC readers using an NFC protocol, a host circuit having one or more modules that communicate with one of the types of local NFC readers via the NFC circuit, and second (e.g., secure) modules that respectively communicate with a specific one of the different types of local NFC readers, also via the NFC circuit, using secure data stored within the second module. A routing circuit is responsive to an NFC communication received from a specific one of the NFC readers, by identifying one of the first and second modules that communicates with the specific one of the NFC readers, and routing NFC communications between the specific one of the NFC readers and the identified one of the modules.

Abstract: A device includes a near field communication (NFC) circuit (114) that is configured and arranged to communicate data with external devices (102). An internal communication circuit (112) communicates data over a microprocessor bus (110). A secure memory circuit (118) stores an identifier that is unalterable in the secure memory circuit. Logic circuitry (116) performs a secure transaction protocol. The transaction protocol includes determining whether a communication, received by the NFC circuit, is addressed to the secure memory circuit; sending, in response to determining that the communication is addressed to the secure memory circuit, the communication to the memory circuit; sending, in response to determining that the communication is not addressed to the secure memory circuit, the communication to the microprocessor bus; and transmitting data, received from both the NFC circuit and the secure memory circuit, to the NFC circuit, the transmitted data including the identifier value and configured for communication with external devices using NFC.
