Fast-casual restaurant Dos Toros is one of the latest chains to go cash-free. Marketing manager Marcus Byrd said that the change saved the team time and that most customers didn’t even notice a difference. “We found that 85 percent of customers use cards already at Dos Toros,” he said in a Cheddar interview. “And of those 15 percent that use cash, we only found that one percent could not go to Dos Toros.” The company first went cashless in October and other chains such as Sweetgreen have made similar changes. One recent study finds that nearly two-thirds of smartphone users dole out cash sometimes, they prefer to use cards or mobile payments. Research firm eMarketer credits speed and convenience, safety, and rewards for the change. Still, going all digital does come with disadvantages. Power outages or WiFi issues mean payments can’t be processed. And the “unbanked” population -- the estimated 7 percent of U.S. households without a bank account are excluded. Byrd says that the company is focused on bringing in those consumers. “We’re actually going to come out with an app next year, and we hope that there’s a location that can accept cash and turn that into money on your app or on a gift card, so that everybody can enjoy Dos Toros,” he said.
