I guess that's just a difference between Germany and the US (or at least Texas). Most of the tablets I've seen in stores and restaurants are actual iPad hardware, the virtual keyboard used when entering information is the iOS keyboard, and the Square app follows the Apple design guidelines. And the rare occasions when I encounter an Android tablet, I recognize it from the virtual keyboard. Case in point: the food hall I mentioned in my above post. When you buy something, it asks you if you'd like to enter your phone number so they can text you when your order's ready. When I chose to enter my number, I instantly recognized the keyboard for that as the Android 4.x keyboard.
