If you should ever be forced by a robber to withdraw money from an ATM machine, you can notify the police by entering your Pin # in reverse.
For example if your pin number is 1234 then you would put in 4321. The ATM recognizes that your pin number is backwards from the ATM card you placed in the machine.
The machine will still give you the money you requested, but unknown to the robber, the police will be immediately dispatched to help you.
This information was recently broadcasted on FOX TV and it states that it is seldom used because people don’t know it exists.
Probably wouldn’t matter anyway. Once you enter the pin you’re gonna have the money in like 5 seconds anyway…At which point the robbers gonna take it and run. Unless a cop was literraly right there, they would never make it there in time to do anything anyway.
And, while you were standing around wating on the Police to show up, you’re signaling to the next robber that you got money in the bank and an atm card on you.
