Overview of How Credit Cards are Stored for Future Use
In coreFORCE and coreSTORE, credit card numbers are never stored. Instead, when a credit card is used, a token is created. Credit card tokenization is the process of de-identifying sensitive cardholder data by replacing it with a string of randomly generated values called a "token." A token is a randomly generated identifier which is used by the merchant gateway to look up the original card number. The only place the card number is stored is on the merchant gateway.
Account Maintenance in coreFORCE
For Account Maintenance in coreFORCE, the account number should always be XXXX-####.
For cards saved in coreFORCE, coreSTORE, or coreCLEAR, #### will be the last 4 digits of the card number.
- For saved payment accounts from coreSTORE prior to 2/28/2022, #### is the last 4 characters of the token, which is a mix of letters and numbers (e.g. XXXX-CY4J)
