Or in other words, an ATM card reader installed by a criminal who wants access to your PIN number. When you insert your card, the data on the magnetic strip is copied, and a camera focused on the keypad captures you typing in the PIN. Everything seems like business as usual so you don’t even know that your identity was just stolen.
How to avoid it: The easiest solution is to use only ATMs inside official banks, and be discreet when you type your PIN number by covering your hand.
People are going to want to shortchange you. A lot. And even after you’ve meticulously counted out the amount you think covers the price of that sweet new hookah pipe you're buying, the vendor will say you’ve underpaid him or her.
How to avoid it: Know the currency well before you start shopping. Say each bill or coin aloud as you pay, to eliminate the possibility of the peddler claiming you’ve made an error in your calculation. And finally, don't just open up a handful of cash/coins, shrug your shoulders, and say, "I don't know, take whatever." But you know this.
