Abstract
An authorization code is entered into a chip card terminal from a chip card. The authorization code is first entered into a chip card and stored in a secret memory location. A state on the chip card is temporarily changed from a first state to a second state. When the chip card is inserted into a chip card terminal within a pre-defined period of time, the authorization code is transmitted to the chip card terminal and the state is reset from the second state to the first state.
Claims6
A method of entering an authorization code into a chip card terminal, the method comprising the steps of:
- entering the authorization code into a chip card;
- storing the authorization code in a memory location of the chip card;
- verifying the authorization code, and
- changing the state of the chip card from a first state to a second state to enable transmission of the authorization code from the memory location to the chip card terminal when the chip card is coupled to the chip card terminal within a pre-defined period of time only in the case of a successful verification of the authorization code and resetting the state from the second to the first state.
A method of entering an authorization code into a chip card terminal, the method comprising the steps of:
- entering the authorization code into a chip card;
- storing the authorization code in a memory location of the chip card;
- and
- changing a state of the chip card from a first state to a second state to enable transmission of the authorization code from the memory location to the chip card terminal when the chip card is coupled to the chip card terminal within a pre-defined period of time and resetting the state from the second to the first state;
- wherein an aural, visual or haptic signal is outputted when the state is changed from the first state to the second state.
A method of entering an authorization code into a chip card terminal, the method comprising the steps of:
- entering the authorization code into a chip card;
- storing the authorization code in a memory location of the chip card;
- changing a state of the chip card from a first state to a second state to enable transmission of the authorization code from the memory location to the chip card terminal when the chip card is coupled to the chip card terminal within a pre-defined period of time and resetting the state from the second to the first state;
- and
- maintaining the second state only if a user continuously performs a predetermined input action during the pre-defined period of time.
A method of entering an authorization code into a chip card terminal, the method comprising the steps of:
- entering the authorization code into a chip card;
- storing the authorization code in a memory location of the chip card;
- changing a state of the chip card from a first state to a second state to enable transmission of the authorization code from the memory location to the chip card terminal when the chip card is coupled to the chip card terminal within a pre-defined period of time and resetting the state from the second to the first state;
- entering an amount or a transaction code into the chip card;
- and
- transmitting the amount or the code to the terminal when the authorization code is transmitted to the terminal.
A method of entering an authorization code into a chip card terminal, the method comprising the steps of:
- entering the authorization code into a chip card;
- storing the authorization code in a memory location of the chip card;
- changing a state of the chip card from a first state to a second state to enable transmission of the authorization code from the memory location to the chip card terminal when the chip card is coupled to the chip card terminal within a pre-defined period of time and resetting the state from the second to the first state;
- and
- erasing the authorization code from the memory location if an unsecure situation is detected during the pre-defined period of time.
