I have a MasterCard that takes a pin. I've been asked to enter the pin at several places, including WalMart. It is a credit card, not a debit card.

Frankly, I'm baffles by these claims that US cards don't work with chip and pin because so far, if I use the chip, I have been required to use the pin.

I also have a corporate amex with a pin set up, but I've never used it.
