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

With chip cards up here , when you setup your card, you can "tap". I had a similar problem, but I noticed the chip area on mine isnt level(edge is lifted) So my card was stuck. Had to use a folded up piece of paper to wedge in to get it out.
Had a atm at the bank eat my card....on a friday. Make sure flat n straight.
