The QR Block plugin provides a few blocks:
- QR: A block that generates the QR code based on its content. Generic purposes.
- Wi-Fi Network Connection: Connect to a Wi-Fi Network via a QR Code.
- QR Post: Share your post with a QR Code.
Also, it renders the QR code of the current post in the Post sidebar. A simple but functional way o load the post on mobile, for instance.
