Error correction level

Error correction capability allows to successfully scan a QR Code even if the symbol is dirty or damaged. Four levels are available to choose according to the operating environment.

Higher levels offer a better error resistance but reduce the symbol's capacity.

If the chances that the QR Code symbol may be corrupted are low (for example if it is showed through a monitor) is possible to safely use a low error level such as Low or Medium.

Possible levels are shown below:

Level Error resistance
L (Low) ~7%
M (Medium) ~15%
Q (Quartile) ~25%
H (High) ~30%

The percentage indicates the maximum amount of damaged surface after which the symbol becomes unreadable.
