News alert for the weekend: Visa and Mastercard aren’t the same thing.
Ok, yes, this is obvious, but please keep it in mind while you’re out in the trenches: Just because a technique fails with a Visa doesn’t automatically mean it’ll fail with a Mastercard. Seriously, many fall into the trap of never trying a Mastercard after a Visa doesn’t work. The difference in behavior is true of payment processors, merchant coding, cash advances, and debit card processors to name a few. It’s also true when dealing with both prepaid cards and with credit cards.
Another hint: Mastercard debit cards open more doors than Visa debit cards unless you’re at Walmart money centers.
