Quick Response Code

Introduction

 
For the past decades, we humans have become accustomed to the representation of data digitally. In the past, we would represent data using lines ("||||" represents 4 and when we cross it to represent 5).
 
After it had been introduced that instead of using lines, we started using bars in which a thick bar represents different data and a lean one represents another and white space represents 0.
 
As time passed, we all know that there are no limits to inventions.
