By default, Packtic generates QR codes based on the Reed-Solomon M (Medium) error correction level - more information here.

There are different levels, depending on the level, with between 7% and 30% of the data bytes missing, the code can still be read correctly.

You can choose between the following 4 levels:

  • Low (L): 7% of data bytes can be restored.
  • Medium (M): 15% of data bytes can be restored.
  • Quartile (Q): 25% of data bytes can be restored.
  • High (H): 30% of data bytes can be restored.

Click on GS1 Digital Link > Generator in the left-hand menu, then on the settings button at the top right.

Choose the level of error correction you need.
