You're desperately in need of an ATM. You walk the streets until you find one outside a nearby bank. You run up to it, only to find a note attached, saying: "This machine is out of cash. The closest ATM is one block south."
You follow the instructions and walk to the one suggested, which is probably in an out of the way location like an alley. You go through with your transaction--but little did you know, this machine is a fake. It uses some combination of the devices described in the previous two scams to steal your banking information.
How to avoid: the interface on ATM machines will tell you when they are out of cash. A bank will never use a note to inform you of cash shortages. Remove the sign and try it for yourself.
