Installation-free chip card reader for secure online banking
In order to use a mobile smartcard reader that can address commercial smartcards conforming to the EMV standard in a simple manner, the invention provides a method for controlling a chip card reader ( 3 ) by a computer system ( 4 ) connectable to smartcard reader ( 3 ), comprising the connection of chip card reader ( 3 ) to computer system ( 4 ) via an interface ( 8 ) designed for data communication on the basis of a protocol provided on a standard basis in operating system ( 11 ) of computer system ( 4 ); the provision of a control program ( 7 a, 7 b ) for controlling the functions of chip card reader ( 3 ), wherein control program ( 7 a, 7 b ) is provided as a plug-in; and the controlling of chip card reader ( 3 ) by executing control program ( 7 b ) on computer system ( 4 ). The invention further provides a chip card reader ( 3 ) as well as a control program ( 7 a, 7 b ) for performing the method.
1. A method for controlling a chip card reader ( 3 ) by a computer system ( 4 ) connectable to the chip card reader ( 3 ), comprising:
connecting the chip card reader ( 3 ) to the computer system ( 4 ) via an interface ( 8 ), which is designed for data communication on the basis of a standard USB-HID protocol provided in an operating system ( 11 ) of the computer system ( 4 );
providing a control program ( 7 a , 7 b ) for controlling the functions of the chip card reader ( 3 ), wherein the control program ( 7 a , 7 b ) is provided as a plug-in; and
controlling the chip card reader ( 3 ) by running the control program ( 7 b ) on computer system ( 4 ), wherein executing the control program ( 7 b ) performs at least one of the following tasks: (i) user authentication, (ii) authorization of a transaction, and (iii) data encryption.
2. The method according to claim 1 , further comprising:
providing the control program ( 7 a ) on a server ( 1 ),
setting up a communication connection ( 10 ) between the server ( 1 ) and the computer system ( 4 ), and
transmitting the control program ( 7 a , 7 b ) from the server ( 1 ) to the computer system ( 4 ).
3. The method according to claim 2 , further comprising:
calling up the control program ( 7 a , 7 b ) by the computer system ( 4 ) from the server ( 1 ); and
transmitting a control command from the chip card reader ( 3 ) to the computer system ( 4 ), effecting the calling of control program ( 7 a ).
4. The method according to claim 1 , further comprising:
providing the control program ( 7 b ) in a memory ( 12 ) of the chip card reader ( 3 ); and
transmitting the control program ( 7 b ) from the chip card reader ( 3 ) to the computer system ( 4 ).
5. The method according to claim 4 , wherein the transmission of the control program ( 7 b ) from the chip card reader ( 3 ) to the computer system ( 4 ) is automatically initiated upon connection of the chip card reader ( 3 ) to the computer system ( 4 ).
6. A chip card reader ( 3 ) for connection to a computer system ( 4 ), comprising:
a port unit ( 9 ) for the connection of a chip card ( 2 ); and
an interface ( 8 ) for connection to the computer system ( 4 ) constructed for data communication on the basis of a USB-HID protocol, wherein the chip card reader ( 3 ) is constructed for control by means of a control program ( 7 b ) that is provided as a plug-in, wherein executing the control program ( 7 b ) performs at least one of the following tasks: (i) user authentication, (ii) authorization of a transaction, and (iii) data encryption.
7. The chip card reader ( 3 ) according to claim 6 , further comprising a memory ( 12 ) in which the control program ( 7 b ) is stored.
8. A control program ( 7 b ) for running on a computer system ( 4 ) for controlling the functions of a chip card reader ( 3 ) connectable to the computer system ( 4 ) via interface ( 8 ), characterized in that the control program ( 7 b ) is constructed as a plug-in, whereon executing the control program ( 7 b ) performs at least one of the following tasks: (i) user authentication, (ii) authorization of a transaction, and (iii) data encryption, and wherein the interface ( 8 ) is designed for data communication on the basis of a standard USB-HID protocol provided in an operating system ( 11 ) of the computer system ( 4 ).
