Abstract
The IC card processor comprises an MPU (51) for access control on an IC (22) for holding card side security code and card information, a keyboard (58A) for input of apparatus side security code used in collation with card side security code, and a nonvolatile memory (59) for storing the apparatus side security code. The MPU (51) reads out the apparatus side security code from the nonvolatile memory (59) when referring to the card information, and issues it to the IC (22). The IC (22) collates the entered apparatus side security code and the held card side security code, and when matched, being set in accessible state from the MPU (51), the MPU (51) accesses and reads the card information, and processes it as specified.
Claims9
An IC card processor for processing card information in an IC card mounting an IC for controlling access from an external apparatus on the basis of the result of collation between a first security code entered from an external apparatus and a preliminarily held second security code, the IC card processor comprising:
- a nonvolatile memory;
- a writing unit which reads the second security code from the IC when the IC card is connected and the first security code is not written in the nonvolatile memory, and writes it as the first security code in the nonvolatile memory;
- a reading unit which reads the first security code from the nonvolatile memory when the IC card is connected, and reads out the card information from the IC after issuing it to the IC;
- and
- a control unit which processes the card information being read out by the reading unit as specified.
An IC card processor for processing card information in an IC card mounting an IC for controlling access from an external apparatus on the basis of the result of collation between a first security code entered from an external apparatus and a preliminarily held second security code, the IC card processor comprising:
- a nonvolatile memory;
- an inputting unit which enters the first security code;
- a writing unit which writes the first security code entered by the inputting unit into the nonvolatile memory;
- a reading unit which reads the first security code from the nonvolatile memory when the IC card is connected, and reads out the card information from the IC after issuing it to the IC;
- and
- a control unit which processes the card information being read out by the reading unit as specified.
An IC card processor loaded with an IC card mounting an IC of which electric state is controlled depending on state control information entered from an external apparatus, the IC card processor comprising:
- a nonvolatile memory which stores the state control information;
- an operator manipulated by the user when controlling the IC state;
- and
- a state control unit which controls the IC state, when the operator is manipulated, by issuing the state control information stored in the nonvolatile memory to the IC.
An IC card processor loaded with an IC card mounting an IC of which electric state is controlled to a first state depending on first state control information entered from an external apparatus, and electric state is controlled in a second state depending on second state control information entered from the external apparatus, the IC card processor comprising:
- a nonvolatile memory which stores the first and second state control information;
- a first operator manipulated by the user when controlling the IC state in the first state;
- a second operator manipulated by the user when controlling the IC state in the second state;
- and
- a control unit which controls the IC state in the first state, when the first operator is manipulated, by issuing the first state control information stored in the nonvolatile memory to the IC, and controls the IC state in the second state, when the second operator is manipulated, by issuing the second state control information stored in the nonvolatile memory to the IC.
An IC card processor loaded with an IC card mounting an IC of which electric state is controlled to a first state depending on first state control information entered from an external apparatus, and electric state is controlled in a second state depending on second state control information entered from the external apparatus, the IC card processor comprising:
- a nonvolatile memory which stores the first and second state control information;
- an operator manipulated by the user when controlling the IC state in the first or second state;
- and
- a state control unit which controls the IC state in the first or second state, every time the operator is manipulated, by issuing the first state control information and second state control information alternately to the IC.
