Are cashiers required to check a credit card for a signature in the U.S.?
The signature actually harks back to the days before every business checked every transaction online. When charge cards were introduced modems didn't exist. Nowadays, stolen credit cards are usually reported within 24 hours and the card won't work. Businesses that face low fraud rates don't bother checking. They probably figure that a certain percentage of charges get charged back because the cardholder claims that they didn't make them, and the credit card company usually just passes the cost on to the merchant, so it's really the merchant who should be worried about fraud since he or she is going to pay for it.  The real question for the merchant is whether checking signatures actually reduces charge backs.  If the credit card is stolen, how hard would it be for thieves to practice the signature on the card a few times until they can reproduce it well enough to fool someone? Businesses that face high fraud rates are often more careful. In New York City, try buying some Nikes on 34th Street, and you'll get your signature checked, your driver's license checked, and they'll call up your 5th grade social studies teacher.
