WIA Stream — when one code isn't enough

A single WIA Code holds up to 1,450 bytes. When the payload is larger — a document, a book chapter, an audio clip — Stream splits it across many frames. A screen plays them in sequence, a camera collects them, and the scanner reassembles the file. No internet, no server. It already ships in the generator.

What matters here is not speed — it is whether the transfer finishes at all. Stream needs every frame. A frame that fails to read must wait for the next pass, and may fail again. So a per-frame reading gap does not average out; it multiplies into the completion time. In our degradation sweep at matched physical size (1064 vs 1088 px, n=17, QR read with ZBar), a high-version QR frame read 52.9% of the time while a WIA frame read 17 of 17. Feeding those rates into a cyclic-broadcast model, a 286-frame QR transfer needs about 8 passes to complete while a 155-frame WIA transfer needs about one.

Read this honestly: n = 17 is a small sample. By the rule of three, "17 of 17" should be read as ≥ 82% with 95% confidence, and the 52.9% figure carries a 29–77% interval. Taking the least favourable end of both, the completion-time gap is still about 2.4×. Screen-to-camera capture on real handsets and printed output have not been measured yet. And QR wins on blur resistance at equal frame size — we only pull ahead once capacity is matched.
