Abstract
The present invention relates to a smart card and to a method of operating the smart card in which the smart card has input/output means enabling the smart card to receive and transmit data regarding individual financial transactions. The smart card has a microprocessor which incorporates a read only memory, a random access memory and input/output ports. The smart card is able to communicate through the ports when suitably positioned within a smart card reader. The internal operations of the smart card are controlled by the microprocessor as determined by program microinstructions that are stored in the read only memory. The microinstructions include a number of application programs enabling the smart card to conduct financial transactions, other related applications and transaction logging operations. The smart card has a secure area and an unsecured area within the random access memory. The microprocessor is programmed to store in the unsecured store area individual transactions which may be automated transactions using the smart card or manual transactions entered as updates into the smart card. The microprocessor is programmed to transfer transactions from the unsecured store a…
