The precursor to this system (iDEAL) has been running in The Netherlands for 21 years. Pretty much all transactions of Dutch webshops and even a lot of foreign webshops (thanks to Stripe support) by Dutch buyers go through iDEAL, as well as most digital P2P payments in Europe.

Many other EU countries have had similar systems for years, but Wero is standardizing it between a bunch of countries.
