When we give gifts via stationary cards, I print a QR code sticker to place in the card that fires a notification when scanned, which lets us know to Zelle the gift because the card has been read. Could be productized for sure.
Why not just put cash in with the card? It seems much easier and more convenient.
In my experience, that risk is very, very low (at least in the US). But yes, if we're talking large amounts of money, I wouldn't put it in a card. That said, I included $500 in cash in a package last month, so my risk tolerance is likely unusually high for this sort of thing.

Ah, that's a bit different (do those services charge a fee, though?). In my social circle, there are only two people (that I know of) who already uses such apps. Everyone else would be pretty annoyed, and probably wouldn't bother to scan the QR code.
It's interesting how much social norms can vary from group to group.
