Abstract
Abstract A data carrier ( 1 ) having an electrical circuit ( 2 ) includes a receiving device ( 6 ) adapted to supply input data (ID) including option control commands (O 1 , O 2 , O 3 , O 4 ), and includes an option control command processing device ( 11 ) adapted to process at least one pair of mutually complementary option control commands (O 1 , O 2 ), (O 3 , O 4 ) and to generate at least one pair of mutually complementary port control commands (GA, GB), (GC, GD), and further includes port means ( 12 ) to which the port control commands (GA, GB, GC, GD) can be applied and which are adapted to be controlled reversibly as regards their port states in dependence on the two mutually complementary port control commands (GA, GB), (GC, GD), and further includes at least one option means ( 13, 14, 15, 16 ) which is optionally accessible with the aid of the port device ( 12 ).

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
187 words
A data carrier including an electrical circuit, which circuit has receiving means adapted to supply input data, which input data may include an option control command, and option control command processing means to which the option control command can be applied and which are adapted to generate a port control command in dependence on the option control command, and port means to which the port control command can be applied and which can be set from one port state into another port state, which is complementary to said one port state, in dependence on the port control command, and at least one option means which is optionally accessible to at least a command processing means with the aid of the port means in dependence on the port states, characterized in that the option control command processing means are adapted to process at least one pair of mutually complementary option control commands and to generate at least one pair of mutually complementary port control commands, and the port means can be controlled reversibly as regards their port states in dependence on the two mutually complementary port control commands.
Claim 2
Dependent Claim
187 words
A data carrier including an electrical circuit, which circuit has receiving means adapted to supply input data, which input data may include an option control command, and option control command processing means to which the option control command can be applied and which are adapted to generate a port control command in dependence on the option control command, and port means to which the port control command can be applied and which can be set from one port state into another port state, which is complementary to said one port state, in dependence on the port control command, and at least one option means which is optionally accessible to at least a command processing means with the aid of the port means in dependence on the port states, characterized in that the option control command processing means are adapted to process at least one pair of mutually complementary option control commands and to generate at least one pair of mutually complementary port control commands, and the port means can be controlled reversibly as regards their port states in dependence on the two mutually complementary port control commands.
Claim 3
Dependent Claim
107 words
A data carrier as claimed in claim 1 , characterized in that the option control command processing means are adapted to process and to supply a security code included in an option control command, and the port means include security code memory means which store at least one security code, and the port means include security code comparison means, which are connected to the option control command processing means and to the security code memory means and with the aid of which a security code supplied by the option control command processing means can be compared with a security code read from the security code memory means.
Claim 4
Dependent Claim
36 words
A data carrier as claimed in claim 2 , characterized in that the port means include a plurality of port stages, and there has been provided at least one option means corresponding to each port stage.
Claim 5
Dependent Claim
45 words
A data carrier as claimed in claim 2 , characterized in that option memory means adapted to optionally allow the storage of data have been provided as a first option means, and the option memory means are formed with the aid of a flash memory.
Claim 6
Dependent Claim
28 words
A data carrier as claimed in claim 2 , characterized in that option bus means adapted to provide optional communication have been provided as a second option means.
Claim 7
Dependent Claim
23 words
A data carrier as claimed in claim 5 , characterized in that the option bus means are formed by means of a USB.
Claim 8
Dependent Claim
23 words
A data carrier as claimed in claim 2 , characterized in that option computing means have been provided as a third option means.
Claim 9
Dependent Claim
186 words
A circuit for a data carrier, which circuit has receiving means adapted to supply input data, which input data may include an option control command, and option control command processing means to which the option control command can be applied and which are adapted to generate a port control command in dependence on the option control command, and port means to which the port control command can be applied and which can be set from one port state into another port state, which is complementary to said one port state, in dependence on the port control command, and at least one option means which is optionally accessible to at least a command processing means with the aid of the port means in dependence on the port states, characterized in that the option control command processing means are adapted to process at least one pair of mutually complementary option control commands and to generate at least one pair of mutually complementary port control commands, and the port means can be controlled reversibly as regards their port states in dependence on the two mutually complementary port control commands.
Claim 10
Dependent Claim
