In New Zealand every store checked to see my credit card signature without fail. Then they match it up with how I sign the receipt. Even a license is not good enough only signatures. Otherwise I never sign
Very often they're just going through the motions but not actually looking at it.
More than once I've used somebody else's CC, they asked for ID, I gave them my ID, they compared the two and accepted it --even though it was a completely different name.
I've seen a costco card accepted where the (bearded) guy using it looked nothing at all like the woman in the picture. (the cashier looked at the card, then looked at the guy as if comparing them and then checked us out.)
