I don't like this gas pump credit card thing at all.

I have read a few stories about how these card readers work. They transmit the info on a skimmed card by Bluetooth. Supposedly you can use the settings section on your phone to look for any other Bluetooth transmitting. If there is one you question, (how would we do that?), then skip that pump. Or pull on the pieces on the reader, if stuck on there with some good two sided tape, SOL. And the bank always holds my chip card until it clears, then I HAVE to remove card before it coughs up the cash.
