Inserting debit and credit cards into machines at the store could soon be old technology.
Big credit card companies like Visa, American Express, and Capital One now issue "contact-less cards."
That means instead of swiping or dipping, users tap their card instead. It's supposed to be much faster, but not enough stores are ready for the transition yet.
About 30 percent of major stores in the country still need the correct equipment. That includes Walmart.
Banks are hoping that the change comes fast -- especially because more public transportation systems are using "tap to pay" cards.
