PHILADELPHIA (CBS) — Everywhere you go, you need to be careful of scams or hacks. That’s even true at the gas pump.

Visa issued a security alert, warning that hackers have found a way to steal credit card numbers when your card is swiped at the pump. Visa says it’s much more sophisticated than credit card skimmers.

The company recommends keeping a close eye on your credit card bill to make sure there aren’t any unusual charges.
