But what exactly is this QR technology? and how has it been proven beneficial for us?

Let’s begin,

What is a QR code?

The QR stands for “quick response.” it is a two-dimensional barcode that stores a large amount of information than a simple barcode.

It was first launched in 1990 by the Japanese firm ‘Denso Wave’. Earlier QR codes were mainly used in the automobile sector for production, tracking, and shipping. But with time other industries also adopted it.

How does QR Technology work?

The QR code comprises of patterns that feature binary codes which can be interpreted to discover the code’s data.

It works in the same way as the barcode at the general store. The QR code has a number of black codes and dots that display certain pieces of information. You just need to scan this code via your smartphone, and that unique pattern will convert that information into human-readable data.

Top benefits of using QR
