Nowadays, it is far more convenient to pay at gas stations with a 
speedpass, use Paypal for online purchases, and pay with plastic rather than holding wads of cash and pockets of loose change.
But instead of now worrying about being mugged for cash, there is a technique to defraud you of your money that is more anonymous, sophisticated, and dangerous — and all it takes is a device that can easily be purchased for $50 online.
This type of fraud is known as card skimming and it involves swiping your debit or credit card through a card reader that has been illegitimately set up to record information from your card’s magnetic stripe.
