QRtoCash

Free. Runs in your browser.

Someone wants to pay you, mistypes your handle, and the money goes to a stranger. A QR code fixes that: they scan it and land straight on your payment page.

Why I ask: I might reach out with a question about how to improve this tool, or to mention other cool tools I build. I will never give your email address to anyone else. You only have to do this once per browser.
