摘要： A device (5; 16; 26) that processes a Near Field Communication type application which device (5; 16; 26) comprises: a host controller circuit (3; 27) that processes device applications, that use the Near Field Communication type application, and that processes a host driver (7; 28) that communicates based on a first interface protocol (NCI; EMV); a NFC controller circuit (4; 33) that processes a Near Field Communication type contactless interface (6; 35) and a controller driver (11; 32) that interfaces with the host controller circuit (3; 27), wherein the host controller circuit (3; 27) processes a first transmission module (9; 30) that interfaces with the host driver (7; 28) based on the first interface protocol (NCI; EMV) and with the controller driver (11; 32) based on a second interface protocol, which first transmission module (9; 30) furthermore processes substantially all none-time critical and/or memory consuming tasks of the Near Field Communication type application and wherein the NFC controller circuit (4; 33) comprises a second transmission module (12, 34) that processes all time critical tasks for the Near Field Communication type application towards the Near Field Communication type contactless interface (6; 35).
