Credit cards are getting more secure

Credit cards in the US are getting more secure with the use of EMV (Europay, MasterCard and Visa). EMV cards (also called smart cards, chip cards or IC cards) store their data on integrated circuits rather than magnetic stripes. This technology reduces the vulnerability of fraudulent in-person transactions. 

The data on magnetic strips is static.  Once it is obtained by the criminals, it can be used over and over.  With the new chip technology, each time the EMV card is used for payment, the card chip creates a unique one-time transaction code.  This code can’t be used again and therefore makes it more secure.  The added safeguard of the chip being embedded on the card helps ensure the card being used is real and that it belongs to the person using it.
