Move keys, contracts and notes between machines that are not on the same network, and never will be. Your payload is split into standard QR frames that play on this screen; a second device reads them back through its camera and checks the result against a CRC32 before showing you anything.

Optical Camera Receptor
Point this device's camera at the transmitting screen. Frames are reassembled in memory by sequence number and verified against a checksum, nothing is written to disk and nothing leaves this tab.
The loopback self-test does not use the camera. It renders the frames and reads them straight back through the same decoder, which confirms the codec works on this machine but is not a test of the optical hop.
