In these times where you can be waylaid by unsavory characters, it pays to exercise some presence of mind.
I received this from a classmate, where she claimed that if one were forced by a robber to withdraw money from an ATM machine, one can notify the police by entering one’s PIN in reverse.
So if your PIN is 1234, you should enter the digits 4321.
The ATM recognizes that the PIN you typed in is the reverse of the original.
The machine will still give you the money you requested, but unknown to the robber, the police will be immediately dispatched to help you.
I don't know how much time the police will take to reach you, but it sure looks like a step in the right direction.
This information was recently broadcast on TV, and stated that it is seldom used because people don't know it exists.
