A near field communication, NFC, device comprising: a front end unit adapted to communicate with an external reader/writer device through an NFC communication protocol including communication establishment requests, the front end unit including a first memory having a first size, the first 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, the first identifier identifying an application or an application family; 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; wherein the front end unit is further adapted to check, when a communication establishment request is received, whether a first identifier included in the received communication establishment request is one of the first identifiers 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 first identifier included in the received communication establishment request, wherein the front end unit is further adapted to generate response information, wherein the response information includes information on whether when a communication establishment request is received the first identifier included in the received communication establishment request is one of the first identifiers 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, wherein, in case the response information includes information that the first identifier included in the received communication establishment request is not one of the first identifiers stored in the first memory, to retrieve a further set of parameters from the second memory, wherein the further set of parameters includes the first identifier included in the received communication establishment request, and to transmit the further set of parameters to the front end unit. a front end unit adapted to communicate with an external reader/writer device through an NFC communication protocol including communication establishment requests, the front end unit including a first memory having a first size, the first 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, the first identifier identifying an application or an application family;
