[Tutorial] How To Create And Use QR Codes

The QR code (Quick Response) is a two dimensions bar code that can be quickly read and decoded by a barcode reader, mobile phone, smartphone, or a webcam. It has the advantage that it can store more information than conventional bar code, and especially data directly recognized by applications. QR codes can contain a web address, text, contact details or an event. Using the photo sensor of your mobile phone and a dedicated application, you can scan QR codes and read the information they contain. In the case of a Web address, you can visit the site linked to a card, you can add a person contact details, send a SMS message and many other things. In this tutorial I will show you how to create your own QR code and use it on your Android phone or iPhone.


There are many different web sites out there that can help you create your own QR code but in my case I will use the one I think is easiest to use. To get started follow steps below

Step 2: Now once you arrive on above suggested web site there are few things you need to provide in order to have your QR code ready for use. First step is to choose Data Type, whether you want to store inside QR code your web site address, YouTube Video, Map Location, Facebook or Twitter profile, Telephone Number and many other things.

Step 3: Now depending of data type you have choose in field 2 add content for your QR code. Since I will be adding a web site url I will add http://thetechjournal.com web site link inside Content field.

Step 4: Another not so important option is to choose a foreground color for your QR code. You can use a color pallet or if you know Hex String code for your color add it in below input field.

Step 5: On the right hand side of the website you can always see how the final results of your QR code will look like.
