And derisking is illegal, so you have to provide a bank account and cards to anyone who wants. The high risk customers just need more follow-up on terms of AML.
Also, I wasn’t able to get a debit card until I was 12, but perhaps that has changed over the past few decades.
My kids got a card at around 5, but they are older now. Not with visa/mastercard of course :)
With respect to closing accounts, there are extremely few cases where people can be denied a basic account with the largest banks, but most smaller banks are not required to provide a basic account, and other account types can be denied at will, and most people have other accounts types (there are something like 7 million basic accounts).
However the homeless problem is virtually non existent in this country, same with the lack of id.
It's just so much more convenient to use digital payments that almost nobody use cash anymore.
Unbanked people is more concerning, as unbanked people include political enemies of the state. The centralisation of power that digital payments allow is concerning.
The other thing which isn't mentioned in this comment chain is that a reason credit is cheaper is that your transaction data is harvested.
Most banks here don't handle the actual payments themselves except the biggest ones.
The small "savings banks" like the one I work in doesn't have shareholders either, they are owned by the depositors. Almost every small town and community here has one.
It is much cheaper for the bank and customers to use cards, but where I live the banks own a payment network that does not involve visa and mastercard so the cost is much lower and there is no rent seeking so card use have no fees.
We also have an app for sending "cash" for free to friends, family and businesses that under the hood are just instant bank payments between the accounts.
