Square has millions of terminals out there, I'm pretty sure the problem is more about training than technology. The front line retail works need to be able to handle all the bitcoin lingo and qr codes and different ways payments can fail. How do you handle refunds? what happens if customer says payment went through but it doesn't show up on terminal? Anyway I'm sure it will happen eventually but it's still early days in bitcoin land.
