Streaming QR codes at 60 FPS achieves nearly 190 KB/s data rate in phone-to-phone tests — browser-based method requires no app, no networking, no pairing, and no permissions beyond camera access

Developer bashalarmistalt released Decimen Optical Transfer, a browser-based proof of concept that uses camera-scanned QR codes to move files between phones.

It works with just a web browser and camera access, without an app, network connection, pairing, or extra permissions.

The system uses fountain coding and self-describing QR frames so transfers can survive missed scans.

Tests reached about 190 KB/s under ideal conditions, with still-strong speeds in handheld use.

It points to a low-friction option for offline or air-gapped device-to-device file sharing.
