I thought about this but I don't think it's any worse than the status quo. A scammer can today get hold of a fake taxi badge, pass a skimmer back to the passenger saying it's going to take payment and achieve the same end. Presumably the argument against square would be that it will desensitise consumers to the risks associated with this and they'll drop their guard. I think this might make sense if consumers had any guard in the first place. However since I'm sure the average person would hand their credit card to a taxi driver to skim today it's hard to see that Square changes anything. At the end of the day this will come down to people being careful about who they hand their card to - just as they are (aren't) on the internet.
