QR Codes - What are they, and how can you create your own?
By Joshua Smith

QR Codes, those small, square-shaped black-and-white patterns you often see on products, advertisements, and even websites, are a fascinating and practical innovation in data storage and retrieval. Here's a friendly guide to understanding QR Codes, and to creating your very own - for free:

A Brief History of QR Codes

QR Codes, short for Quick Response Codes, were invented in 1994 by a Japanese company named Denso Wave, a subsidiary of Toyota. The initial purpose was to track vehicles and parts during the manufacturing process. They needed a system that allowed high-speed component scanning, which traditional barcodes couldn't provide. While QR Codes were initially used in industrial settings, their ability to store more information than standard barcodes, and their ease of use, led to a wider adoption in various fields.

How They Became Popular

QR Codes gained popularity due to their ability to store a wide range of information, from URLs to contact details, and even Wi-Fi passwords. With the advent of smartphones equipped with cameras, QR Codes became even more accessible. People could now scan these codes using their phones to access information instantly. Before long, businesses started using QR Codes for marketing, providing quick access to their websites or promotions. And, as you no doubt recall, during the COVID-19 pandemic, QR Codes became a touchless way to check in to venues, to share menus in restaurants, to receive health information, and more. That's arguably the biggest factor in encouraging a rapid adoption of the technology, as many people were forced to use QR Codes for the first time during the pandemic.

What Information Can QR Codes Store?

Types of Data:
