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

Decimen Optical Transfer: fountain-coded QR file transfer.

A developer has created a proof-of-concept data transfer system that shuns any dedicated app requirement and neatly sidesteps mandatory networking, pairing, or giving permissions beyond camera access. Instead, the method transmits information between devices by streaming data via rapidly updating QR codes at up to 60 FPS via the browser your smartphone already has. The test info shared by developer bashalarmistalt on GitHub backs claims that these transfers can run at up to 190 KB/s. This low-friction two-device screen-to-camera data transmission technique is dubbed Decimen Optical Transfer: fountain-coded QR file transfer.

Had an idea for air gapped file transfer, able to get 120 KB/s from r/vibecoding
