How is that better than a card payment? Cards are accepted by far more merchants, have dispute rights, are inexpensive (in Europe) to process, supported by Apple & Google Pay, superior checkout experience, etc.

I've never used their dispute system, and I don't think that holds much value in Europe. At least in Germany a contract is a contract, if I claw back the payment the other party will just start the collections process. A process that has teeth and generally will recover the money from me, worst case by garnishing wages.

On the other hand Visa and MasterCard are not neutral actors. They have used their market power in the past to pressure merchants to change according to American moral values. And with the current administration I have little faith that this will stay at moral values

1. Credit cards are not that common. People usually have debit cards. Those can sometimes be used online but they're not widely accepted. My debit card is Maestro, which is not accepted in many places.

2. Even with my Mastercard credit card, the process is still inconvenient. For small purchases, it's fine. But for larger ones, there is an annoying second factor authentication, I have to enter a special password, and the wait to receive an SMS.

3. Visa and Mastercard fees. Most of the time these are paid by the merchant. But sometimes the customer has to pay more if the payment method is credit card. Some places don't accept these at all.

In general iDEAL is simple, secure and convenient. Not only to pay online, but also for example for splitting a bill with friends. I'm very happy to see this being adopted more widely in Europe.

The whole flow is so much better than card purchases, where you have to enter all the data (or see your password manager's autofill fail) and then you have to go to your credit card provider's app to acknowledge the transaction.

The vast majority of Dutch online transactions are done because pretty much every Dutch online shop supports it. Also many international shops through Shopify and Stripe. Many Dutch online shops do not support credit card payments. So iDEAL is the far lower friction option here. And there is no American company in between (at least for most national payments). It's great to see this system, that served us two decades by now finally get rolled out across Europe. They tried it before in the early 2010s, but the non-Dutch banks were fighting turf wars.

Cards are reliant on US companies -> Visa / Mastercard. The European Payment Initiative wants to remove reliance on the US. Perhaps there can be a ECB payment rail/network that would support cardlike payments too.
