The product comes already assembled or it is a kit? If not, do you plan to sell it in kit form? For us that can't 3D print or build PCBs but want to tinker with it.

Apart from QR, it would also be nice to pay by scanning an NFC tag, which is sometimes much faster than scanning a QR code, but of course, the question now is how to get the tag to the user. It would be complex to set up a logistics system just for this.
In any case, I think it's a very good idea. I could see myself using it every time I go to the barber.
I also like the fee system and I think it can be useful for open source projects where they collect donations, as an alternative to Buy Me a Coffee, for example.
