Wow... clever bastards. I only wish I had thought that up!
Actually, I was wondering what keeps people from dressing up like delivery men, and dropping off a fake ATM in the mall or someplace public like that. It steals cars and PINs and just reports a "Sorry, communications error. Please try again later" message after you attempt a withdrawal. Those little ATMs that are chained down inside convience stores and the like are getting quite ubiquitous... and lots of people use them w/o thinking twice.
