What, why would you need Wero for that? That would just be an EPC-QR-Code using SEPA. Wero is just some cancer in between to sniff off user emails and phone numbers in my eyes.
The European Central Bank is working on regulation regarding the "Digital Euro" which is a bit in a marketing hype loop using block chain and other terms as a hype, while fundamentally trying to come up with a Euro-Zone-Wide approach to create a mostly anonymous digital currency, with some offline capability. If they come up with a final working concept paper, this would become legally mandated with low charges.
Wero is a product by banks, trying to be faster. Trying to have an established platform under their control, which is well established before ECB is ready with D€.
