Three years ago I wrote about how I was one step closer to not only going cashless -- I had pretty much already done that -- but also going walletless. (That's one of the things about writing a daily blog -- there's a public record.) I still carry a wallet in most cases, but I couldn't tell you the last time I paid for something using cash here in Toronto. It was probably at a Vietnamese restaurant.

I did, however, notice on my trip last month that Germany and Austria are still quite reliant on cash. Many places only accepted cash and many places wouldn't accept credit cards under a certain minimum spend. Fewer opportunities to just tap as well. I had forgotten how annoying it was to carry around lots of coins. You really need a change purse.

Still, a paradigm shift has taken place. And because of this shift, there's a growing movement in cities toward banning cash-free businesses. Philadelphia, Chicago, San Francisco, New York City, and Washington, DC are all working on policy. The concern is that not accepting cash discriminates against lower-income patrons.

According to the Federal Deposit Insurance Corporation (FIDC), approximately 8.4 million US households (6.5% of all households) were "unbanked" in 2017. This means that no one in the household had either a checking or savings account.

An additional 24.2 million US households (additional 18.7% of all households) are estimated to be "underbanked", meaning they have at least one account at an insured institution, but they also rely on outside financial products -- such as payday loans.

When surveyed, somewhere around half tend to cite "not having enough money" as one of the reasons for being "unbanked." But the good news is that the percentage of people without a bank account seems to be declining (see above chart).

This is important because we all know where things are headed. And banning cashless businesses isn't going to stop that march. There are deeper issues that need to be addressed. Here is an excerpt from a recent CityLab article on the topic:

“I certainly don’t think [this bill] is the right long-term solution,” said Rogoff. “The future does not lie in this direction. The future lies in giving people free debit cards and financial inclusion.” He cited the case of India. The country launched a program to decrease the number of unbanked and saw the percentage decrease from 47 percent of adults in 2014 to 20 percent unbanked in 2017 according to the World Bank Global Findex Report. “If India can manage to give people free debit cards, so can the U.S.” Rogoff said.
