clamp

If they try to rob you while getting money from an ATM, do not resist. just dial your pin backwards. for example, instead of 1234, dial 4321. As a result, the machine will secretly notify the police and push out money, but it will be tightly clamped by the dispensing device, as if it were stuck. This function is available in all ATMs, but not everyone knows about it. tell your friends, someone might find it useful.
