Kind of pointless to use once you are already on the site. 😉
Basically I was thinking at some point I want to make a page for my pets, make a QR code for it and then put the code on their tags. Â The idea being that if lost and someone finds them, they scan the code and get all the info they need and then some to ensure the critter makes their way home.
Now to turn on my non-evil anus URL, make a page and ensure hosting is paid up for the next 10 years now that I got the simple basic QR code idea down.
