I was thinking about the possiblity to buy something with QR-Code using a Wallet (Bitcoin, Ethereum …). i.e. I may have Bitcoin and I want to buy a product (having a qr-code) using my wallet. How can I do that? is it possible? I have posted because I didnt find anything. May be my question may be incorrectly asked. I’m not trying to implement something yet (may be in the future? 
) I just wanted to know if someone could help me with this information. I have searched and found nothing about payment through scanning of the qr-code (the qr-code belongs to a product and via the scan the amount is deducted from my wallet!) That is what I’m talking about. Thks for your time.
