How Does a QR Code Work? The Technology Explained

Last year, an estimated 11 million households scanned a QR code in the United States alone. Even though this seems like a huge number, QR codes are used worldwide and produce even bigger results elsewhere.

Most people know how to use a QR code, but not many know the history behind it. As technology continues to grow, the QR has stayed very useful in a variety of industries.

How does a QR code work exactly? Keep reading through this guide to find out.

What Are QR Codes?

Before you can learn the answer to, “how does a QR code work?”, you need to understand what it is. Yes, it is an icon you can scan to pull up a website on your device. However, it’s much more than that.

A QR code, also known as a quick response code, is quickly readable by a cell phone. To create this, a combination of spacing is used as a type of Matrix Barcode.

When you scan a QR code, it conveys information that someone wants you to see. They have a wide range of uses for multiple industries and even schools.

How Does a QR Code Work?

In modern times, the QR code consists of seven different parts. Each part works together to create a pixel pattern that might look like a crossword puzzle to some.

One element is just as important as another because they convey certain information. Even the empty spaces help with the print direction, error tolerance, and timing. One QR code pattern is unlike another QR pattern.

QR software is different depending on the generator you use. This c# qr code generator can help with error correction and much more.

The Invention of QR Codes

QR technology wasn’t always around, but now it seems to be everywhere. At first, the POS system was created as the baby version of the barcode.

However, it wasn’t enough to keep up with the demands for technology. Barcodes can only store around 20 alphanumeric characters of information and have one direction of coding.

The QR code came along due to the DENSO WAVE whose lead developer was Masahiro Hara. First, supermarkets contacted them because they wanted to make barcodes more versatile and able to contain more information.

From there, the development of two directions of coding came about. The square shape allowed for both vertical and horizontal coded information.

The use of QR codes spread fast after this and DENSO WAVE went public without getting patent rights.

Using QR Codes for Business

Any business in any industry can make use of QR codes. The QR code technology was made for everyone to benefit from.

You now know the answer to, “how does a QR code work”, but what will you do with this information? If you use this technology wisely, you’ll benefit from free advertising and a streamline of services.
