Data modules are small square-shaped elements across the QR Code. They store the information you encode in the QR Code. These modules can be customized by changing their patterns or adding a color to them.

If you add a logo to your QR Code, some data modules near the center will be removed. It is done so to accommodate the logo image.

This removal of data modules introduces an error in the QR Code. So, to ensure QR Code’s high scannability, you need to have an appropriate level of error correction. Error correction ensures that the QR Code can scan well even after the addition of a logo. Here are the different error-correction levels:

  • L (7%)
  • M (15%)

  • H (30%)

For example, if the color of the QR Code is black, the background must be white in color and vice-versa.

6. Poster
