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
Cards are accepted by far more merchants,
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.
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 only superior aspect of Visa/Mastercard payments is that they are more widely accepted, and that's something that can be changed.
There are huge countries (China, India, Brazil, ...) where people moved from cash to mobile payments.
Europe has always been in the forefront of this space, Swish exists since 2012, it's about time we get a pan-European solution.
