Hi,
The credit card solution / CCI (credit card interface) was designed to be PCI compliant / allow PCI compliance). If we choose to store credit card numbers, that data is encrypted such that a user would not have access to the stored value. The credit card number is presented as XXXX456. The CCI also offers the ability to use tokens, where the credit card number is not within IFS. If holding of a credit card number as encrypted data is a concern, the option to use tokens is certainly available.
Best regards,
Thomas
