Just before the holidays, retail giant Target became one itself for hackers, who successfully stole millions of customers' personal credit card numbers.
Just weeks later, there is a renewed call by both security experts and customers for new, safer ways to pay for merchandise with something known as chip-and-PIN, or smart, cards.
While chip and pins are already being used readily in Europe and Africa, banks and merchants in the United States have been resistant to making the switch because of the billions in costs to upgrade terminals and issue new cards. And consumers would have to adopt a new behavior.
The head of at least one major credit card security firm says these new chip-and-PIN cards will be widely used in the United States by 2020.
