The credit card field provides 4 options for saving a credit card number. One of these options is to save the entire credit card number, which is not recommended. Saving a credit card number to your database subjects you to PCI compliance. This means if you store credit card details in your WordPress database, the credit card numbers either have to be masked to display only the last 4 numbers of the CC as the default Formidable option does, or you need to encrypt the credit card number if you store the full credit card number.
