Mozilla Firefox has a Great plug-in (One amongst many) called Mobile Barcoder 0.2.0.
Its basically the solution for that moment when you find an article you want to read, but want to read it on your mobile instead of your laptop. But dont want to type that long URL. Simple solution.. Make a QR code out if it 😉
Simple mouse over thingy, generates a QR on the go; scan it & walk away 🙂
Im looking to get some of that functionality on my blog, mouse over style. I might ‘ve found the right plugin, but have yet to test it..
