OXI Credit Card Vault Handling
The Credit Card Vault functionality can only be activated by the IFC>Credit Card Vault application function which is hidden. Please contact your regional office to get this application function activated and to find out more details.
In OXI, new functionality has been added to store the Unique ID of the Credit Card Vault functionality as well as the last 4 digits of the credit card number (to be used for identification) and an expiration date for the Unique ID.

Subsequently all transactions related to that customer's charge will communicate using this Unique ID. See Credit Card Vault for further details on the Opera Functionality of this feature.
Note: The last four digits of the credit card number and the expiration date are used in Opera for identification purposes only and remain visible on screens throughout the Opera application.

When the Credit Card Vault functionality is disabled, plain credit card information would be present in the original message as is current functionality.
