Software decoding these QR codes could suggest to open them with dedicated software, depending on their URI scheme.

For instance, to open a webpage: https://www.example/

To send an email: mailto:contact@email.example

To share geographic coordinates: geo:48.867564,2.364057

Redundancy is the duplication of information in the QR code to correct errors during decoding. A higher rate will produce a bigger QR code, but will have a better chance of being decoded correctly.

Number of pixels in each white band around the QR code.
