A bunch:

- internetwork payments

- interbank payments

- fraud prevention and insurance layer

- retail consumer debt underwriting

- payments infrastructure and endpoint standards, security, and deployment

CBDCs do take away a fair amount of responsibility from existing private EFT, and I personally think can be a net positive, but they're a piece of the puzzle.

"a world where CBDCs will exist" could also be phrased as "a world where CBDCs do not yet exist".

Do you mean insofar as people will be able to pay without carrying cash or using a credit card?

I assume reasons will be similar to why many prefer credit cards to debit cards: cash flow issues, extra fraud protections, creating a credit history for future loans, rewards points, etc.

The value of debit cards will be significantly diminished, though.

For context, CBDC stands for central bank digital currency, e.g. https://www.dnb.nl/en/innovations-in-payments-and-banking/di...

How do CBDCs handle payment disputes? Aside from credit, that's a big value of a card.

Maybe smaller. Maybe larger. But that's a big assumption that CBDCs will exist on a broad basis anytime soon (or ever).

Credit? It's the (non central)bank accounts what lose meaning, imo

There is value in stable asset management. I don’t foresee a future where credit-based systems are superseded by something else.

Dude do you not have a credit or debit card?

Seriously asking

Tech is never the hard part in payments.

Begging the question a bit aren't we with the assumption that CBDCs will exist?
