QR Code Decoder

The black and white boxes that you have often seen in some magazines, newspapers, or websites are known as QR codes. It will be interesting understand how these QR codes are read, scanned, and decoded by your mobile phone. After these phases, the required and specified task is performed. These codes are very similar to barcodes and act as initiators of a pre-defined process. The QR code contains some decoded information that is unique to a product or service. These codes have a number of random boxes and lines that contain lots of information.

These days, QR codes are becoming very popular as an advertising tool. There are lots of companies that have these codes printed in magazines or other media to provide information on their products or services. People can scan these codes and decode the codes to access the information very easily. The decoding is done by the QR code decoder software which can be downloaded from the Internet or it may be made available by the smartphone manufacturer. The QR codes can also contain lots of customized information such as your business card with your contact details or a web page that has your resume.

Coding and Decoding

QR codes can be read by your smartphone if you have the right kind of software to read it. You need to have a reader that scans, reads, and decodes the QR code. In almost every smartphone which is available in the market today, the QR code decoder software is pre-installed. In the case where the software is not installed, you can easily get this from the Internet. When you are looking for a QR code decoder, you have to be very careful about the compatibility of the software. If you are using a decoder which is not compatible with your phone, there’s no way that you will be able to read the information in the QR code. The decoding software is different for Android and different for iPhones.

To scan these QR codes, you should be careful that your hands are as steady as possible. Sometimes, a little shake of the hand can lead to the misinterpretation of the pattern of the boxes, and hence you will get an error while scanning. When the scanning is complete, the decoding software will take a specific amount of time to decode it. The time taken by the software depends on the processing speed of the decoding software as well as the amount of data stored in the QR codes. This decoded information is then processed as per the required task. If the decoded information is in a word document, then it will open it in the word processing application and if it is a link to a website, then it will open the browser automatically. These QR codes are very easily processed and directed.


You can even develop your own personal QR code without any complication. A number of websites are available that have free QR code generating software. You just need to enter the desired information and the software will make your own QR code. Then, you can use this QR code as your business card in various formats or you can print it on your brochure or whatever purpose you may have in mind. You can also download the QR code in your PC so you can use it as per your requirement. The amount of data that can be stored on these QR codes varies from software to software. Obviously, superior software will store more data on the code with less error. When decoding, a better decoder will decode the QR code and it will retrieve the information with more efficiency and speed.


QR codes are generally composed using 8 bits. These coded forms are written by the Reed-Solomon Algorithm. This algorithm has been used to write coded signals for a long time. QR codes are basically of two major types which are divided on the basis of the amount of data they can store. The first type is the Micro type of QR code which has lower storage capacity. The Micro type is mostly deployed for personal use. Most of the websites on the Internet offer the Micro type of QR code. The other type of QR code is the Standard type QR code which has much greater storing capacity and it is less prone to misinterpretation errors.
