Kimtag is run by a group of experienced techies who maintain the project for the fun of it. The Kimtag project now has tens of thousands of users from around the world and we try and make sure that it's as reliable and well maintained as possible !
Kimtag was launched in February 2011. It's designed to help people use QR Codes and NFC Tags by allowing them to share multiple connections (Twitter, Facebook, etc) quickly and easily.
You can set up and individual Kimtag and download a QR Code for free. Yep, free.
We used to sell a few products to help offset the costs but the running of the store cost more than the money made so we now run the project for free. We don't currently sell management licences although people who had purchased them in the past now have the luxury of being able to use them for free !
