There's two functions of Wero: peer-to-peer and consumer-to-business transactions. TFA is about consumer-to-business.

If you look at the video for how Wero online payments work (https://www.youtube.com/watch?v=Bu5_X3oSgHM), you'll see that an EPC QR code could just as well be used (with a banking app installed instead of Wero).

With Wero you probably also get automatic processing of the incoming payment, without having to connect the financial transaction to a purchase yourself. But payment through bank transfers is also available through the payment service providers and costs less than Wero (at least it costs less when using Mollie; the Stripe fee is the same for Wero and bank transfer, and Adyen apparently hasn't published the Wero fee yet). So you'd still get the same service for less money.
