In release 1611, the credit card number is masked so only the last 4 digits are shown,.

In July2017, this feature was removed. This is causing issues for my company. We use the credit card number as the Card ID, but do not want the entire number to show.

EXPENSE MANAGEMENT: CONFIGURATION RELATED TO EMPLOYEE’S CARD ID
In prior releases, the employee’s expense credit card ID was designed to only allow up to 10 characters and displayed the last 4 digits entered as the card ID. The ability to enter more characters was required for organizations that have an agreement with their credit card company to use another key to identify an employee’s credit card number without entering the credit card number. This key is often greater than 10 characters and is typically between 20 and 30 characters.

This feature has lengthened the Card ID field for the employee’s credit card setup (Human resources > Workers > Employees > Expense tab > Credit cards) and provides a parameter to validate whether a 15- or 16-character number is allowed as the card ID. The parameter, Enter employee credit card number, is found on the General tab of the Expense management parameters form (Expense management> Setup > General > Expense management parameters). By default, credit card numbers are not allowed as the expense credit card ID.
