No need to...
This is how the scam works:
1. You introduce your debit/credit card in the automatic teller.
2. You enter your pin and proceed with your transaction.
3. When you want to withdraw your card it gets stuck within (by means of double sided tape or some sticky gum).
4. The robbers are nearby (no sense in living your card overnight) and they had (sometimes) placed the sign saying you should report your card the next day or in 24 hours.
5. You leave your card inside the teller (if you were so gullible) like an open book for thieves as you never got the chance to log off.
6. The thieves take money from your account till they get to the limit allowed per day.
7. Then they withdraw you card and go shopping with it. For payment with credit or debit cards there is no need for pins, just signature and most times the signatures are not even checked to see if they are a close match.
Best remedy?
* Withdraw money in the tellers placed in the banks; the thieves are less likely to mess up with the teller in front of the bank's camera.
* Should you card get stuck, use the telephone that most banks have next to the teller or get a telephone fast and immediately notify your bank.
Now, another word of advice: Carry another card, I have found cards unreliable as a few times mine did get caught inside the machine. Some times I was sure it wasn't a scam, just a problem with the bank. I once couldn't withdraw any money because due to a problem with my bank it emptied my account and it took 23 days to clear the mess. So, always have a Plan B, you know, "money is like toilet paper, when you need it you need it NOW".
