What's in your wallet? If you're like many Americans, there probably isn't a lot of cash-if you carry a wallet at all. According to a survey by U.S. Bank, over half of Americans surveyed only carried cash half the times they went out-and when they did bring their greenbacks, half kept only $20 or less in their wallets. With the rise of fintechs like mobile payment apps and digital wallets, consumers are relying less on cash and more on digital payment options.
