New protection at the pump?

 I spent some time in eastern Pa. recently and noticed several times there that when I inserted my credit card at the pump for gasoline, I was asked to enter the ZIP code of the card's billing address..

This is new and I assume it is a way to detect stolen credit cards. Maybe the thinking is if someone is using a gas credit card away from home, it could be a purloined card. I don't know if pumps in my home ZIP code also ask.

But whatever, it is s small price to pay if it inceases security. Anyone else notice this?
