"This whole "but you can do it on the black market for $20!" argument is, pardon the Latin, fucking ridiculous." Nice way to add 'black market' in there to try to dismiss a valid point. You can get card readers from legitimate businesses. They are valid peripherals used all the time. Do a search for 'usb credit card reader' on Google. All those results are not black market. As an aside, it's funny how you have a problem with GP saying 'Are you serious?' and thinking it implies your point is stupid but then take the exact same dismissive tone for your whole post. "I seriously can't believe there are people in this thread, who identify themselves as IT specialists, siding with Square because credit card processing is a lost cause. " The fact of the matter is that people hand their cards over all the time to pay for things and no one ever looks to see what kind of device it is. When you are paying for something in a shop, do you check out the credit card processing machine first to make sure it's secure? When you hand your card over to the waiter to take to the back and pay for your meal, do you follow him to make sure he isn't swiping it into another machine or writing the number down on paper? Nope. And the fact that the square reader is a plaintext device, like a lot of the readers on point-of-sale systems, really doesn't mean anything.
