Near field communication device and method for near field communication

A method for near field communication, comprising:

• storing, in a first memory of a front end unit, the first memory having a first size, a first number of sets of parameters of an application, wherein each set of parameters includes a first identifier and a second identifier;
• storing, in a second memory of a processing unit, the second memory having second size which is larger than the first size, the application and a second number of said sets of parameters of the application, the second number being larger than the first number;
• receiving, at the front end unit, a communication establishment request from an external reader/writer device, the communication establishment request including a certain first identifier;
• checking, each time when a communication establishment request is received, whether the certain first identifier is stored in the first memory, and if yes sending 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,
• generating, at the front end unit, 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;
• sending, each time when a communication establishment request is received, the response information to said processing unit;
• evaluating, at the processing unit, the response information and controlling which sets of parameters are to be stored in the first memory, the control being dependent on the response information.

A non-transitory computer-readable storage medium storing computer-readable instructions that, when executed by a computer, cause the computer to perform a method comprising:

• storing, in a first memory of a front end unit, the first memory having a first size, a first number of sets of parameters of an application, wherein each set of parameters includes a first identifier and a second identifier;
• storing, in a second memory of a processing unit, the second memory having second size which is larger than the first size, the application and a second number of said sets of parameters of the application, the second number being larger than the first number;
• receiving, at the front end unit, a communication establishment request from an external reader/writer device, the communication establishment request including a certain first identifier;
• checking, each time when a communication establishment request is received, whether the certain first identifier is stored in the first memory, and if yes sending 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, generating, at the front end unit, 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;
• sending, each time when a communication establishment request is received, the response information to said processing unit;
• evaluating, at the processing unit, the response information and controlling which sets of parameters are to be stored in the first memory, the control being dependent on the response information.

A near field communication system comprising:

• an external reader/writer device;
• a near field communication device including 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 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;
• 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.
