QR Code Error Correction

Currently there is no rule on which QR code error correction level to use, venues are free to pick their error correction levels depending on their own situation.

Level Correction Percentage
L (Low) 7%
M (Medium) 15%
Q (Quartile) 25%
H (High) 30%

If there is no preference then level M is recommended.
