It sounds a bit like the Dutch Tikkie with the QR codes and instant transfer. Of course, in the EU most bank wires are already free when using SEPA, and often nearly instant as well. This Tikkie thing is a way to easily create a payment request for people who can't be arsed to simply carry cash (and raise the country's resilience to system failure in the process).

Brazilian living in NL, experienced in both. I think biggest difference is Tikkie doesn't give you an easy identifier. Great for privacy, but being able to send money to your email/phone number makes a difference for some real time use cases. QR code helps, but it is not the same.
