About it
QR codes still scan when part of them is lost, because error correction can rebuild missing codewords: about 7, 15, 25 or 30 percent at levels L, M, Q and H.
Here you scratch a code or stick a label on it where you tap, draw on it with a marker, tear it from the corner or the edge nearest your tap, burn it from the nearest corner, smudge it, or do what only a code of splats allows: blur, shrink, grow, jitter or fade its splats, drift its color, curve it, tilt it or set it moving. After each change the meter reads the very picture on the stage and counts each block's lost codewords against what it can fix. Show all four levels side by side, or tap Heal it to watch Reed–Solomon decoding set each block right.
