I heard ordinary QR codes can hold up to 3KB of data.

How much data can this one hold?

The simple answer is:

4-color (standard): 7500 bytes

8-color: 8750 bytes

monochrome: 5000 bytes

Those numbers are with the standard, fairly high ECC setting (~20% of the image) that I settled on for video-based transfer. If we want to be more aggressive and use half the error correction:

4-color (standard): 8400 bytes

8-color: 9800 bytes

monochrome: 5600 bytes
