I know this is a long shot but I was wondering if there is anyway to block a specific credit card number. There is an individual who frequents our establishment on busy days and walks away with the signed copy of his receipt. About a month later we get the challenge and inevitably loose because we have no signed copy. He uses the same card every time, so I was hoping to block just that card. We are using PC Charge to process the charges. Thanks in advance!
