FORT WORTH (CBSDFW.COM) – Nearly two thirds of all paper currency is made in Fort Worth. Literally billions of bills roll off the presser every year at the U.S. Bureau of Engraving and Printing. But in most everyday transactions, however, cash is no longer the preferred currency. Replaced by credit cards, PayPal and debit cards — cash is somewhat passé.

“When you go to certain places in the world, people just walk around with big wads of American dollars. That’s how they’re doing their buying and selling,” said Mike Davis with the SMU Cox School of Business.

Conversely, many Americans still keep their savings in cash. It’s one reason a $100 bill is now almost as popular as the $1 bill.
