QR codes can be used to encode lots of different kinds of data viz.
- URLs
- Free text
- Contact
- App
- Phone
- SMS
I've tried constructing a free text QR code, and it's pretty cool - my phone reads it and displays the text, making it available to copy and read.
Might be interesting to do something with these...
I used https://www.the-qrcode-generator.com/ which requires a sign-in for Dynamic QR codes (presumably ones that use their site as the repository of the info, and a level of indirection through it).
