When you store a credit card on file the PN Reference associated to that card is stored for no longer than one year. Once a PN Reference is expired it can no longer be renewed.  Thus it is important to renew PN Reference numbers associated to credit cards on file before they expire.  To renew the PN Reference (so that credit cards do not begin failing) you will need to run the RQ6704212.  

It is important to note that unless excluded or removed, cards on file that failed to renew will continue to process each time you run this report. Depending on the number of cards on file this can significantly increase the number of transactions.  Therefore, we recommend keeping your cards on file "clean" by removing those that cannot renew (card is expired, account closed, etc) to prevent those attempts.
