There are many projects within the Wikimedia and MediaWiki universe that include QR Codes. This page summarises these.

There are two broad types of use: projects that are about creating QR Codes regardless of what they're used for; and projects that are primarily about where the user ends up when using a code, for which the QR Code is just a convenient way to share a URL. Some cover both.
