It was first designed in 1994 by a Japanese company named Denso Wave with the intention of tracking vehicles during manufacturing. Since then, QR codes have become increasingly popular as a way to quickly and easily share information. In this article, we will explore the history of QR codes, how they work, and their various uses.

History of QR Codes

As mentioned earlier, QR codes were first created in 1994 by Denso Wave, a subsidiary of Toyota, as a way to track vehicles during manufacturing. The first QR code actually stands for Quick Response code, referring to its ability to be decoded at high speeds. However, QR codes did not gain widespread use until smartphones became popular in the late 2000s and early 2010s.

With the rise of smartphones, QR codes became an easily accessible way to share information, as users could simply scan a code with their smartphone camera to access a website or download an app. Today, QR codes can be found on advertisements, product packaging, business cards, and even in museums and art galleries.

How QR Codes Work

QR codes work by using a series of black and white squares arranged in a specific pattern. The information is stored in binary code, which can then be read by a QR code scanner. When a scanner reads a QR code, it aligns the squares with a grid and reads the pattern of the squares to decode the information.

To create a QR code, you can use a QR code generator, which will allow you to input the information you want to share and generate a code that can be printed or displayed digitally. There are also QR code scanners available as mobile apps that can be downloaded onto smartphones.

Uses of QR Codes

QR codes have a variety of uses, some of which include:

— Advertising — many companies use QR codes on advertisements or product packaging to provide consumers with additional information about their product or service.

— Event invitations — QR codes can be used on event invitations as a quick and easy way for guests to RSVP or access event details.

— Art and museums — many art galleries and museums use QR codes to provide visitors with additional information about the artwork or exhibits.

— Payment — QR codes can be used for payment through mobile wallets or peer-to-peer payment apps.

— Authentication — QR codes can be used for authentication purposes, such as logging into a website or verifying identity.


Overall, QR codes have become an important tool for sharing information in a quick and easy way. As technology continues to advance, we can expect QR codes to become even more prevalent in our daily lives. Whether you are using them for advertising, event invitations, or payment, it’s clear that QR codes are here to stay.
