How to make QR codes that can be scanned by a mobile phone.

A QR code (Quick Response code) is a type of matrix barcode (or two-dimensional code) first designed for the automotive industry. More recently, the system has become popular outside of the industry due to its fast readability and large storage capacity compared to traditional UPC barcodes. The code consists of black modules arranged in a square pattern on a white background. The information encoded can be text, URL or other data - like in the pages of magazines, in advertisements and even on TV and Web sites, and is readable by dedicated QR barcode readers and camera phones. You can make a QR code to link to your website, your email address or something else.

QR code has been used and printed on Chinese train tickets since late 2009.

 It is quite easy to make the QR code and short url as well. Popular URL shortener Bit.ly automatically creates QR codes for every URL. In order to see QR code, simply add “.qr” at the end of your shortened URL. Another one is qr.net and I used it for my web site.

Google’s URL shortener, goo.gl, can also do the same and more – you can see the QR created for every URL and traffic sources in the statics page.

To scan the QR, you need QR app. If you have a smart phone, go to the App store and search for a QR code reader. You’ll find several free apps. Run the App and then hold your phone’s camera over a QR code to read it. For iPhone 4s, I use QR Reader from here. It is quite easy and effective.

Now, it is time to make QR code for your business.
