Generating a QR code is easy using Google's URL shortener and a simple URL hack.
- First, copy the URL of the website you'd like to generate a QR code for. Head over to goo.gl, and paste in the URL.
- You'll get a shortened URL that will redirect to the URL that you pasted, something that looks like this: http://goo.gl/4Yvle.
- Now, copy that short URL, and add ".qr" to the end, and enter that in your address bar: http://goo.gl/4Yvle.qr. That will give you an image that you can copy and paste into your poster.
You can also get statistics on how many people have scanned that QR code and visited your site by adding a "+" to the end of the shortened URL: http://goo.gl/4Yvle+.
