If someone (thief) is forcing you to withdraw money from ATM using your card you just do one thing.... Enter your card and type your ATM pin number in reverse order... For example, if your pin is 1234, just type 4321... It will alert the nearest police station..... All the kind of ATM centers have this facility...
