Method and system of tracking and providing an audit trail of smart card transactions
First Claim
1. A method of tracking and providing an audit trail of transactions with a smart card, comprising:
- storing information representing a monetary transaction consisting at least in part of a transaction amount in a permanent memo on an application of a microprocessor chip of the smart card of at least a first cardholder;
reconciling a load value on the smart card by transmitting the stored transaction information from the permanent memo on the smart card application to an on-line host system;
deleting the permanent memo from the smart card application;
wherein storing information further comprises holding the transaction amount in escrow on the smart card application and excluding the escrowed transaction amount from the load value of the smart card until the permanent memo is deleted;
wherein the escrowed transaction amount represents one of a load transaction to the smart card and an unload transaction to the smart card, and deleting the permanent memo further comprises increasing the load value on the smart card by the escrowed transaction amount if the escrowed transaction amount represents a load transaction and decreasing the load value of the smart card by the escrowed transaction amount if the escrowed transaction amount represents an unload transaction; and
wherein the monetary transaction comprises an off-line transaction with the smart card.

Abstract
A method and system for tracking and providing an audit trail for off-line smart card transactions includes storing information representing a monetary transaction in a permanent memo on an smart card microprocessor and holding the transaction amount in escrow until the stored information is transmitted from the smart card, for example, at an on-line terminal, to a host on-line system for logging to a tracking system. The monetary transaction includes a transaction with an off-line device, such as another smart card. The escrowed transaction amount represents, for example, a load transaction to one of the smart cards and an unload transaction to other smart card. Once the memo is deleted from the respective smart cards, the load values of the respective smart cards are incremented or decremented by the transaction amount. Alternatively, the smart cards may be provided with a card-to-card key, in which case, a permanent memo is stored only on the receiving smart card.

39. A system for tracking and providing an audit trail of transactions with a smart card, comprising:
-
means for storing information representing a monetary transaction consisting at least in part of a transaction amount in a permanent memo on an application of a microprocessor chip of the smart card of at least a first cardholder;
means associated with the smart card for reconciling a load value on the smart card by transmitting the stored transaction information from the permanent memo on the smart card application to an on-line host system; and
means associated with the smart card for deleting the permanent memo from the smart card;
wherein the means for storing the information is adapted for holding the transaction amount in escrow on the smart card application and excluding the escrowed transaction amount from the load value of the smart card until the permanent memo is deleted;
wherein the escrowed transaction amount represents one of a load transaction to the smart card and an unload transaction to the smart card, and the deleting means is adapted for increasing the load value on the smart card by the escrowed transaction amount if the escrowed transaction amount represents a load transaction and decreasing the load value of the smart card by the escrowed transaction amount if the escrowed transaction amount represents an unload transaction; and
wherein the monetary transaction comprises an off-line transaction with the smart card. - View Dependent Claims (40, 41, 42)

43. A method of tracking and providing an audit trail of transactions with a smart card, comprising:
-
posting information representing an off-line monetary transaction between a smart card of a cardholder and an off-line device consisting at least in part of an amount for the transaction in one of a permanent load memo and a permanent unload memo on an application of a microprocessor chip of the smart card;
holding the amount of said one of the permanent load memo and the permanent unload memo in escrow on the smart card application upon completion of the off-line transaction between the smart card and the off-line device and prior to a reconciliation with an on-line host system;
if the transaction information is posted in the permanent load memo on the application of the microprocessor chip of the smart card, allowing the cardholder to view the amount of the permanent load memo without allowing the cardholder access to the amount of the permanent load memo prior to the reconciliation with the on-line host system;
if the transaction information is posted in the permanent unload memo on the application of the microprocessor chip of the smart card, allowing the cardholder to view the amount of the permanent unload memo while reducing a load balance on the smart card by the amount of the permanent unload memo prior to the reconciliation with the on-line host system;
on an occasion subsequent to completion of the off-line transaction between the smart card and the off-line device, allowing the cardholder to make a connection between the smart card application and the on-line host system to reconcile the smart card load balance by transmitting the information in said one of the permanent load and unload memo to the on-line host system;
if the information in said one of the permanent load and unload memo is transmitted to the on-line host system to reconcile the load balance on the smart card, deleting said one of the permanent load memo and the permanent unload memo from the smart card application; and
if the information transmitted to the on-line host system is from the permanent load memo, incrementing the load balance on the smart card by the amount of the permanent load memo.
