When working a retail job I once (and only once) saw a credit card with a photo of the person it was issued to on the back. It was also about the only card I really bothered to check ownership on because signatures were useless.
Thankfully we've now got chip & pin, completely removing the need for minimum wage retail staff to verify ownership of credit cards.
Here it is, Planet Money Ep. 564: The Signature (16:20)
"Today on the show: the signature. It's supposed to say, "This is me." But where did the idea come from? And why are we still using it? We consult a rabbi, a lawyer and a credit card executive."
If you're not going to do chip and PIN (and you should), why not just chip and nothing?
