This user property is used with the Display Mask Char user property to display only the last 4 digits of a credit card number or account number, such as xxxxxxxxxxxx9999. This user property is set on a separate calculated field that is displayed in the UI instead of the field containing the entire credit card number or account number.
For example, in the Quote business component, the Credit Card Number field is the encrypted field that stores the credit card number. The Credit Card Number - Display field is a calculated field on which the following user properties are set:
- Display Mask Char with a value of x
- Encrypt Source Field with a value of Credit Card Number
The applet field that displays the masked credit card number should reference the Credit Card Number - Display field.
