method for controlling the mobile terminal device, computer program product, software tool, carrier wave embedded data signal, mobile terminal device capable of performing wireless data transactions, wireless data transaction system, and, Smart card module. According to the present invention, a method for controlling the mobile terminal device is provided, wherein the device comprises a smart card module and a near field communication module. In the first operation, smart card operation on the mobile terminal device is started, which results in activation or switching of the smart card module. The smart card application can be user initiated or based on the mobile terminal device location. This is the case, for example, if the mobile terminal device is located in the area of a point of sale terminal, the smart card application will start automatically. In addition, the time-controlled start of certain applications is conceivable. then it can be determined whether the smart card application started is an application for performing data transactions with external entities and in the case of an affirmative determination, a connection between the smart card module and the nfc module will be activated.
