Can I Use My Android Phone To Process Credit Payments?

Yeah, there are a couple services. I know people who've used the Square for a couple years for CD sales, and theyb were enthusiastic, I checked last summer and it seemed like a good deal, but never followed thru and actually used it. And some one of the biggies announced a service in the last couple months--Google or Amazon or PayPal, but I don't remember who. I think the Square is squareup.com, but google them to make sure.
