<p>A near field communication (NFC) device comprising: a front end unit adapted to communicate with an external reader/writer device, the front end unit including a first memory having a first size, the memory being adapted to store a first number of sets of parameters of an application, wherein each set of parameters includes a first identifier and a second identifier; a processing unit including a second memory having a second size which is larger than the first size, the second memory being adapted to store the application and a second number of said sets of parameters of the application, the second number being larger than the first number; wherein the front end unit is further adapted to receive a communication establishment request from the external reader/writer device, the communication establishment request including a certain first identifier; wherein the front end unit is further adapted to check, when a communication establishment request is received, whether the certain first identifier is stored in the first memory, and if yes to send a response to the reader/writer device, the response including a respective second identifier, the respective second identifier being part of the same set of parameters as the certain first identifier, wherein the front end unit is further adapted to generate response information, wherein the response information indicates whether when a communication establishment request is received the certain first identifier is stored in the first memory or not; wherein the front end unit is further adapted to send, each time when a communication establishment request is received, the response information to said processing unit; wherein the processing unit is further adapted to evaluate the response information and to control which sets of parameters are to be stored in the first memory, the control being dependent on the response information.</p> |
