How to Scan and Create a QR Code?

The conventional wisdom says, ‘be short and sweet’, but thanks to modern technological innovations, even if you have 7,089 numeric characters or 4,296 alphanumeric characters, or 2,953 binary characters long and can still relish the short and sweet status!!! Wonder how? QR Codes does it for you in style.

QR code stands for Quick Response codes and was developed by DENSO Corporation’s Industrial systems Product division (now known as DENSO WAVE) in 1994. Unlike the barcodes which are single dimensional, QR codes are two dimensional which enable it to encode more data in horizontal and vertical direction. While a barcode requires an external database to find out what is encoded in it, but a QR code can hold a whole lot of information in it like contact details, text messages, geo location, link to a webpage or video and it doesn’t require an external data base. Even though the makers of QR Codes, DENSO owns the patent for QR Codes, they are not exercising it, thus it is free of cost.

A Typical QR code would look like this: (There is a surprise hidden in the below code…try to unlock…)


 As you can see in the above figure a QR code consists in the arrangement of squares in order to encode the information. The scanner understands the orientation of the QR code with the help of the three larger squares in the corners. As the QR codes were initially meant for automobile factory use, where getting stained is obvious, it has superb error correction mechanism.  Even if a maximum of thirty per cent of the code is damaged, the data in the code can still be retrieved.

QR Code Applications

QR codes create an essential link between the physical and online world. Publishing a large advertisement in the front page of magazine or a newspaper would surely make a hole in your pocket. With QR codes, you need to give only a short advertisement, and all other details together with the link to your website can be encoded in the QR code. Same is the case with the business card and other advertisement mediums like flyers, where QR code lets you limit yourself to minimum space with maximum data.
