Idea of ATM Icon
It's a rectangle with a cut-out image as if posted in the middle that allows you to click it and utilize it. You'd insert your card into a slot into this machine, and all around this video playing device(LED) you'd get the option to hit 6 buttons running alongside it. This is where you get to choose what or hot much money you'd take or put into the machine.
