<p>A credit card system (100) is provided which has the added feature of providing additional limited-use credit card numbers (126) and/or cards. These numbers and/or cards can be used for a single transaction, thereby reducing the potential for fraudulent reuse of these numbers and/or cards. The credit card system finds application to 'card remote' transactions such as by phone or Internet (112). Additionally, when a single use credit card is used for 'card present' transactions, so called 'skimming' fraud is eliminated. Various other features enhance the credit card system which will allow secure trade with the use of elaborate encryption techniques.</p> |
