The QR code doesn't work

When a QR code cannot be scanned in 4planning, there can be several causes. Below are the most common problems and solutions.

The QR code is hard to see

A QR code has to be clearly visible to scan properly.

• Avoid reflections or bright sunlight.

A damaged or blurry screen

A damaged screen or a low resolution can make scanning difficult.
