What is a QR code how it works and ways you can create your own

Most of us have seen a square puzzle like image on most of the places that accept digital payments. That image in the square is called a QR code or quick response code. As the name suggests this code is used to access data or function quickly. Although we use this code often, not many of us know what it actually is and how it works. Here is everything you need to know about QR code.

What is QR code and how it works

QR codes fall in the similar category as the barcode

we see on products in a supermarket. It is an image that can be scanned to reach the data it stores. While barcodes have a limited usage, a QR code can be used for numerous purposes and it can also be scanned through a smartphone camera. Each QR code consists of a number of black dots and squares that store data. When these dots and squares are scanned together they deliver stored information that can be accessed by us. The QR code system was invented in 1994 by a Toyota subsidiary called Denso Wave.

An average QR code can store around 7,000 digits or about 4,000 characters. The data can also be a combination of both. This means it can be used to store URLs, phone numbers, e-mail address, Instagram username and several other things. The appearance of the QR code depends on the types and size of data it contains.

These days QR codes are used almost everywhere. Tickets, payments, business cards and many such things that are required to deliver information are stored in QR codes.
