<p>A method for carrying out an application with the help of a portable data carrier, wherein the data carrier includes two separated communication interfaces. According to the method, a user transmits via a first terminal specified input data for processing by the application to a server via a first data connection between the first terminal and the server. Then, authentication data for authenticating the application based on the input data of the server are transmitted via a second data connection between the server and the data carrier which is connected via the first communication interface with the first terminal. The authentication data are then transmitted from the data carrier via a third data connection to the second terminal. The third data connection is realized by means of the second communication interface. Finally, upon confirmation of the authentication data by the user via the first or second terminal confirmation data to the server are transmitted via at least the first or second data connection, whereupon the server executes the application.</p> |
