The Ultimate Guide to QR Codes: Uses and How to Generate Them
QR codes are everywhere — from restaurant menus to product packaging, business cards, posters, and even payment systems. But what exactly are QR codes, why are they important, and how can you create one in seconds? Let's break it down in this simple guide.
Did You Know?
QR codes were first created in 1994 by a Japanese automotive company to track vehicles during manufacturing. Today, they're used by millions of people worldwide and saw a 750% increase in usage during the COVID-19 pandemic.
What Are QR Codes?
QR stands for Quick Response. A QR code is a type of two-dimensional barcode that stores data in a square grid of black and white squares (called modules). When scanned with a smartphone camera or QR scanner app, it instantly directs users to the stored information.
Advantages Over Traditional Barcodes
- Higher data capacity - QR codes can hold up to 4,296 alphanumeric characters compared to just 20 digits in standard barcodes
- Omnidirectional scanning - Can be scanned from any angle or direction
- Error correction - Can still function if up to 30% of the code is damaged or obscured
- Versatile data types - Can store URLs, text, contact info, Wi-Fi credentials, and more
- Smaller footprint - Store more data in less space
