You can do the same thing in the US. The problem is that businesses can't easily do this without collecting bank routing information from customers, which is effectively "secret" because it allows anyone to debit money directly from their bank account, so they're reluctant to provide it.

What's needed is a low- or no-fee system for requesting payments from someone without collecting any secrets from them. The technology to do this is not hard -- use public key cryptography, or just require the customer to approve merchants before they can make debits. But the customer's bank has little incentive to implement this because the customer won't choose a different bank over it and meanwhile the banks own the credit processing networks charging the high fees.

Which is why people are looking for an external solution.

You seem to be talking about authorising businesses to take money from my account without needing further approval. A direct debit.

Parent is talking about transferring money to someone else's account, which is easy and requires no secrets or authorisation.

What problem needs to be solved?

This would be essentially solved with a standardized system for customers to give each merchant a separate bank account number which really refers to the same bank account but could be revoked individually if that one is compromised or you want to remove the merchant's access, but the banks don't have the incentive to provide this when they're the ones getting the credit card fees.

How does it work in the US?

But with the same information someone can also make a withdrawal, which is problematic.

Supposedly FedNow is the solution to this, but it will be a while before this functionality is exposed to end users.

That allows you to authenticate with the service you're doing business with, which is all that ever needs to happen because centralized identity systems are just an attack for correlating your activity across services and devices.

Soon it will impose savings limits, expiration dates to incentivise spending [0] all tied up to your digital identity.

When governments propose extremely unpopular policies on its people, it will be certainly used against their own people to quell and discourage protests much easily than before.

You will then realise that all these digital identity solutions such as eIDAS, digital euro and wallets are essentially no better than Worldcoin. Governments around the world would love to do exactly what Worldcoin is doing for onboarding to a future CBDC.

No thanks and absolutely no deal to both of that.

Here in CZ, the law was setup in a way that gives advantage to banks compared to other identity providers, these banks created one consortium, which is essentially monopolistic provider, with ~80 % market share, asking private services providers significant money for identity services.
