Abstract

Near field communication (NFC) device including a processor and a front end unit (FEU) to communicate with an external reader/writer device. The FEU stores, by first memory, a first number of sets of application parameters, each set including first and second identifiers. The processor stores, by second memory, the application and a second number of the sets. The FEU receives a communication request from the external device, including a certain first identifier. The FEU checks, when the request is received, whether the certain first identifier is stored in the first memory. If yes, a response is sent to the external device, including a respective second identifier, which is in the same set of parameters as the certain first identifier. The FEU sends, each time a request is received, a response to the processor. The processor controls which sets of parameters are stored in the first memory based on the response.
