I would be great to have a QR code on geocoins and travel bugs that will bring you to the geocaching site to log the item. Imagine at the event, just scan the item, click log as discovered or what ever and done. No more writing down all codes. TBs already have some fake bar code or something on it. Why not QR codes.

I guess the guy who blurred the code didn't know QR codes support error correction when part of the code is destroyed, LOL.
