>The next time you see a sign in a shop or restaurant window stating “No cash accepted,” you’re really looking at a business excluding many unbanked and underbanked people.
Speaking of the US, I would like to know how much overlap there is between businesses that don't accept cash and people who are unbanked or underbanked. My limited exposure to no-cash businesses suggests these establishments are not losing/excluding customers as these were not places that would be patronized by un/underbanked consumers. But I'm not confident where I live and where I have seen this practice is indicative of generalizations.
