MasterCard Masking

 

1. "MasterCard has introduced a new requirement regarding debit card numbers: dispute forms submitted to MasterCard must use specific masking format 123456XXXX1234 to be accepted and not fined.  When enabled in the RegE Affidavit Wizard, this setting displays the full debit card number while completing the affidavit, but masks the number when the affidavit is generated to ensure compliance with MasterCard's guidelines."
