This SHOULDN'T be so hard! When you use the business debit card as a credit card online, you need to enter the 16 digit account number, expiratio date, and 3 digit code on the back. The problem is that there's NOT number on the front, NO expiration date on the card, and NO 3 digit code on the back. SO, how do you use this darn card online as a Mastercard?????
