What is a QR Code?

QR Code, short for Quick Response Code, is a two-dimensional barcode that one can read using a smartphone camera. You can encode more than 4000 characters in a 2D QR Code. The commonly used codes are static in nature and they contain fixed information like address, URL, phone number, email address, or any other text content. 

This matrix barcode (2D barcode) was first designed for the Japanese automotive industry in 1994. The black and white look was inspired by the famous board game Go. Back then, QR code was used to scan auto components at a fast pace and track their movement. 

As per a survey conducted by Adobe Systems in 2014 about 25-30% of people in developed countries used QR codes. Fast forward to 2020, Statista has intimated that about 11 million people in the US alone are using QR codes. It’s also estimated that by 2022, about 5.3 billion coupon codes will be redeemed using a tiny QR code.


Can a QR code store image or sound?

Yes, you can store sound or image in a QR code. However, the size of data should be 3KB or less. This size can also vary depending on different versions of the QR code.


Can QR codes be colorful?

Yes, it’s possible to use a certain combination of colors in QR code. You shouldn’t use a color combination that makes it difficult for a QR scanner to capture the image of your code. For example: avoid a combination of a green background and blue QR Code.


What are Dynamic QR Codes?

Just like the name suggests, a dynamic QR code contains information that can change with time. It also means that you can edit such code after completion and change the destination address without the need to print code again and again.
