From Techcrunch:
add “.qr” to the end of any shortened link, and Google will generate a QR code for it. For example, the link http://goo.gl/SJhz would become http://goo.gl/SJhz.qr. The new trick was tweeted about earlier today by Google’s chief spam fighter Matt Cutts.
Of course the shortened link has to be a goo.gl shortened link, but we think you get the point.
Google isn’t the only one trying to push QR codes. We know that when we do application reviews and roundups, like our own Kevin Krause’s introduction post, we have requests for QR codes so you can quickly gain access to download the apps we mention. Well, rest assured we have an automatic solution coming soon that we’re pretty darn sure will meet and exceed your expectations.
Until then… scan away!
