Using the last four digits of the card number or checking account, the transaction ​amount and the invoice number, ​the system ​determines if a duplicate transaction has been submitted. The merchant can also set a specific period of time during which the system should check for duplicate transactions. In cases where the cart generates a new invoice number for each transaction,​ the module can be configured to ignore invoice number and check only the card number and amount. While this method of handling duplicates is straightforward and will prevent duplicates, it is not the most user friendly option, as demonstrated by the following example.
