It's nice that the EU is giving room to such innovation, but I wanted to point out that stuff like this is quite widespread in India: Every shop on the road nowadays has a QR code you scan to make a payment using any UPI[0] compatible app. Thus, the age old problem of a shop not having change is quite rare nowadays (if you're not a minor that is, because all UPI apps are 18+). UPI is centered around your phone number…
>if you're not a minor that is, because all UPI apps are 18+ I didn't know this, and neither do minors in India who use it for daily purchases.
Interesting, I haven't seen this in my city (Chennai).
I myself learned of this when I attempted to set up GPay, but was blocked from signing up because I'm not 18
