From their site:
>It is not possible to send Wero payments to friends & family via a web browser or on a computer
https://support.wero-wallet.eu/hc/en-us/articles/25599074240...
So its pretty clear they have no plans to support plain browser access. Which is a very strange decision to me.
It's primarily an online payment system, not a money transfer system. It has worked since forever (20+ years, it's a rebranded Dutch system) from web browser. Still does.
The horse's mouth seems to contradict this. The subject is Wero, not Ideal.
