Q: I need your help in either proving me wrong or dispelling an urban legend that said as a "safety tip" if you are ever robbed at an ATM to enter your pin in reverse order. This, supposedly, will still dispense the cash but will also automatically phone the nearest police department and have officers rushed to the scene. I wrote the person that sent the forward to say that I suspected this was not factual. My thoughts were that an ATM only knows your correct pin, any other series of numbers is just wrong, not an emergency warning. I also said I doubted that every ATM (or any for that matter)in the world was wired into the 911 emergency system. The individual responded that "someone" who sent it to her had already checked this with the police and that it was true, although, they were a little vague on the specifics. My thoughts were that if this isn't true (and I suspect it isn't) that it could put anyone trying into a dangerous situation. Anyway, can you give me an authoritative response to this question? Thanks foryour help.

A: You are correct on this as an urban legend. Snopes.com is considered the best buster of urban legends and this ATM PIN one is there as well. This legend isfalse, but there is some fact to the origin of it. You can read it all here.
