Joe and I were wondering something today: why do so many ecommerce sites ask you for your “Card Type” (Visa, MasterCard, whatever) during the checkout process?
Isn’t the card type always derivable from the number? (e.g. — MasterCard starts with five, Visa with four, Discover with six, Amex with three, etc)?
We can’t figure out why so many sites ask for this. What are we not getting?
