  • Integrated circuit card with means for performing risk management
    Patent number: 6016963
    Abstract: A microprocessor-based device having a memory unit and a processing unit operatively coupled to the memory unit. The memory unit has one or more risk parameters stored therein, and the processing unit is capable of performing real-time risk management analysis of transactions performed by the IC card using the risk parameters. Preferably, the microprocessor-based device is an IC card.

  • Transaction recovery in a value transfer system
    Patent number: 5982293
    Abstract: A value transfer system for transferring value in transactions between electronic purses as electronic cash has a transaction failure recovery procedure whereby a pending log stores transaction messages after they are sent. On detection of an error an interface device (IFD) can issue a payment resume command to re-send the last transaction message and resume the transaction.

  • Electronic toll payment
    Patent number: 5857152
    Abstract: A system for toll payment by electronic cash identifies an electronic purse and effects value transfer over a communication system without stopping the mobile (vehicle or person). Mobile identity MID is temporarily correlated with purse identity PID and one or another identity is erased on satisfactory or non-satisfactory completion of the transaction thereby allowing non-payers to be pursued while preserving the principle of anonymity.

  • Value transfer system
    Patent number: 5778067
    Abstract: A value transfer system which allows value to be transferred between electronic purses comprises computer which controls the loading of purses with value and the redemption of value from purses, a special bulk purse or purses and a value meter securely linked thereto which registers the total net value issued to the bulk purse or purses. Draw-down of value and redemption of value transactions are effected with the bulk purses.

  • Tamper proof security measure in data writing to non-volatile memory
    Patent number: 5715431
    Abstract: A method of writing data to non-volatile memory such as electrically erasable programmable read only memory (EEPROM) in a smart card provides a write status region of EEPROM which is examined on each reset of the card. If the preceding write operation was unsuccessful, perhaps because of deliberate manipulation of the card, a recovery procedure is implemented. If recovery is successful, the card operation can be run. Otherwise the card is unusable.
