Might want to be careful with this: encouraging people to hastily scan QR codes can be as bad as encouraging them to click unknown links in emails!

True. Never thought of it like this. I do like the idea though. Suppose it would be safer to paste the LNURL to receive instead of a qr code ? 🧡
Might suffice just to add a warning: a QR code is probably safe if people are only scanning from a wallet (not a QR code reader) and also checking that it's not an invoice - but in a rush I don't know if everyone will do that.
