External secure unit
First Claim
1. A method for operating an external secure unit,in which the external secure unit comprises at least the following:
- an antenna coil configured to operate at a first frequency;
amemory for storing data;
a chip module including a processor for processing the data, the chip module further including a second antenna coil configure to operate at a second, different frequency, wherein the chip module is electroconductively connected to the first antenna coil, and wherein the antenna coil and the second antenna coil are positioned orthogonally to each other, allowing the chip module to select which antenna coil has an optimal coupling position relative to a reader, and to implement the selected antennal coil to transmit or receive data; and
one or more interfaces disposed on the external secure unit for receiving data from a communication device or sending data thereto, wherein at least one of the one or more interfaces is not supported by the communication device, wherein the at least one interface not supported by the communication device allows the communication device to communicate through the interface not supported by the communication device to other communication devices that have the interface not supported by the communication device;
wherein the communication device comprises at least;
a memory for storing at least one application program;
a processor for processing and executing the application program;
at least a first interface for sending data to the external secure unit or receiving them therefrom; and
at least a second interface for sending data to a transmission network or receiving them therefrom;
wherein security-relevant data necessary for executing the application program in the communication device are stored in the external secure unit, and the communication device requests the security-relevant data from the external secure unit for executing the application program.
