I read on the internet that:
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.
My friend told me that he checked at two ATM's but both of them first caught the card and they were unable to get out the cards from the machine. Then the IT department of the banks begin working on the machines.
Well I do not have card to check. If someone could share his knowledge or experience in this regard with me and other fellows, it would highly appreciated.
