The movement towards credit-only transactions appears to be driven by efficiency and the problems associated with accepting and handling cash.
Now comes government. San Francisco is about to require brick-and-mortar retailers to accept cash as payment. Philadelphia and New Jersey have already banned the growing paperless practice that critics say discriminate against low-income people who may not have access to credit cards.
Investors should take note. Some business models, such as cashless Amazon Go stores use a combination of apps and credit cards to speed the shopping experience and reduce labor costs. In low margin businesses, such as retailing, productivity gains are crucial.
Incidentally, Warren Buffett carries cash and a credit card.
