QRio: Bridge the air gap
I kept having to type long passwords by hand into work laptops that didn't have my password manager installed. The typos alone made it annoying enough to fix. QRio generates a QR code containing whatever sensitive information you need to move, with a timeout that destroys it after a set period. All processing stays on your device.
The question it started with was small and practical: can you bridge the air gap without relying on infrastructure you don't control?
