FAQ

About QRCode ErrorLevel

The ErrorLevel means that the QR code can be scanned normally after being blocked, and the maximum area that can be blocked is the error correction rate.

Generally, the QR code is divided into 4 error correction levels: Level L can correct about 7% errors, Level M can correct about 15% errors, Level Q can correct about 25% errors, and Level H can correct about 30% errors. When the content encoding of the QR code carries less information, in other words, when the value link is short, set different error correction levels, and the generated image will not change.
