Beware The Skimmers
This Santa Rosa Press- Democrat story gives good reason not to use a debit card to buy gasoline. Credit cards have some added protections debit cards don't have.
In this case some bad guys installed information skimmers inside gas pumps and surreptitiously recorded the credit card information as customers bought gas. I found that rather scary as I'd only heard of skimmers being placed on the outside of gas pumps (and ATMs). With a scam like this you'd be unlikely to know anything was wrong until you saw the charges show up on your account.
This made me realize using a restricted card for gas purchases, like the Renner Petroleum card I use, is a much better idea than using a Visa or Mastercard as they can only use my card at other Renner cardlock sites.
