Rigged ATM machines
Especially in areas where the ATM is not really well visible, you should always pay attention to ATM machines you use. Some of them are modified by thieves to clone your card and stole your pin. Always try to notice the place where you put the card and notice the top part of the machine to see if there is any camera or something odd. If you notice something odd just use another ATM. Always use on hand to cover the display when you digit the pin. If you get your card cloned you can lose hundreds of euros per day before you notice.
