Are cashiers required to check a credit card for a signature in the U.S.?
Working retail myself, I do not accept an unsigned card without verification.  If I received one I would ask for ID and verify the photo with the Name. I would also let the buyer know it was unsigned and remind them that anyone finding it can sign it and use the card without issue. Putting on the back of the card "SEE ID" is the way buyers have protected themselves from thieves as long as people are actually looking at the cards.  How does this protect?  1- a lost card cant be signed by a complete stranger as there is already writing on the card.  2- It provides a photo identification for use. I know with today's technology that this is going away and fewer people are actually checking but shame on those companies who handle the cards and don't look. Obviously this process does not apply to self checks, but safety protocols there require a pin of some form that only the authorized user should know.
