QR codes are everywhere—from product packaging and restaurant menus to business cards and marketing campaigns. But how many of us actually know how they work? As technology becomes more integrated with our daily lives, understanding the tools we use matters more than ever. In this post, we’re diving into the science and evolution of QR codes, and why they’re essential in the modern digital marketing toolbox, especially when paired with platforms like Fierce Links.

What is a QR Code? A Quick Response (QR) code is a type of matrix barcode that can store a massive amount of data compared to a traditional barcode. It was invented in 1994 by Masahiro Hara from the Japanese company Denso Wave to track automotive parts. Unlike regular barcodes, QR codes can store data both horizontally and vertically, allowing for quicker scans and more information.
How Does It Work? QR codes are made up of black squares arranged on a white background. Each QR code has:
- Finder patterns that help scanners identify and align the code
- Alignment patterns for accurate decoding even when distorted
- Timing patterns for consistent data interpretation
- Data and error correction areas, ensuring functionality even if damaged
When scanned by a device with a QR reader, the code is translated into text, a URL, or other data instructions.
Why Are QR Codes Relevant Today? In the era of contactless transactions and mobile-first users, QR codes bridge the gap between physical and digital experiences. They’re fast, secure, and incredibly versatile.
Use cases include:
- Instant access to websites or product details
- Streamlining check-ins or RSVPs
- Fast redirection to payment portals or donation pages
