EU bureaucrats have nothing to do with this. They are pushing the Digital Euro instead.

Wero is an initiative from a group of European banks united in EPI (European Payment Initiative). The tech is partially based on the Dutch iDEAL (which EPI acquired a few years ago).

iDEAL has been around in The Netherlands for 20 years and is used for most Dutch online payments (also supported by Shopify and Stripe) and P2P payments through Tikkie/betaalverzoek. The whole system is really nice and smooth and definitely much nicer than PayPal in many ways. Almost no online stores use Paypal here because iDEAL works so well.

Given this history and the iDEAL people working there, I'm sure Wero will be fine after a few iterations.

EPI are still EU bureaucrats ;) They are supported by the ECB and EU Commission and the ECB also pushes for the digital euro.

That's good to know that Wero for online shops is "just" iDEAL rebranded, that was news to me. There is an info page here: https://sowieso.wero-wallet.eu/nl-en/consumer
