SAN FRANCISCO (AP) — San Francisco is about to require brick-and-mortar retailers to take cash as payment, joining Philadelphia and New Jersey. Critics say the divisive paperless practice discriminates against low-income people who may not have access to credit cards. Cashless retailers say it’s safer and more efficient not to handle cash. The legislation is likely to pass Tuesday. It comes as San Francisco officials are striving to make life more equitable in a city with an enormous wealth gap.
