Perhaps the fake PIN would only show a preset of money in the account (and still call the cops)? If the robber didn't know the victim, they might buy it.
Not sure the situation in other countries, but in the US you aren't liable for any money lost in an ATM robbery. So this would be helpful to the banks, but not the victim.
Just the knowledge of this would discourage ATM robberies from happening. If you knew that you'd only get x bucks, and that the police would be called as the transaction was happening, you'd be less likely to try this technique.
Well, I think you'd have fewer ATM robberies, but the ones you did have would be more violent, because now the victim is effectively armed with a crude weapon. So the robber is going to be more violent to intimidate the victim into NOT using that duress code.
Eh, I just have two bank accounts and only keep a few hundred in the one I use for debit card payments/withdrawals. If I need more, my smartphone app is right there.
Ah... this is a good benefit to having multiple accounts. I am always confused by those with only one bank account. My current account never goes above 2K, mostly sitting at around a few hundred. This gives me a perpetual feeling of not having very much money, so I don't spend too much.
If you've got some armed psychopath (or maybe more than 1) holding a weapon to you or threatening you on a dark night your probably not going to be thinking rationally.
All sorts of stuff is going through your head like "should I use the duress PIN?" , "can I remember the duress PIN?" , "will they know if I use it?" , "how could they know?" , "What if they somehow DO know, is it worth the risk?"
