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
