The POS terminals I talk about usually support at least MasterCard, Visa, Maestro, Vpay, and the German scheme Girocard (which in reality are multiple networks in its own). Some even more and they are still much faster than either using the same card in the US or using a US-issued card in the US. I'm honestly quite baffled as to why. I haven't tried a US card in a German terminal yet and neither looked closely at ATM speeds.
