QR Code vs. Aztec Code: Which is Best for Mobile Tickets?
Ever noticed the square barcode on your airline boarding pass? It's probably not a QR Code. Here's why.
For most digital use cases, the QR Code is king. But in the world of mobile ticketing—from airline passes to train tickets—the **Aztec Code** often reigns supreme. They look similar, but the Aztec Code has several technical advantages that make it ideal for this specific job.
QR Code: The People's Choice
**QR Codes** are ubiquitous. They are great for marketing and linking to websites. Their main disadvantage in a ticketing scenario is their finder pattern—the three large squares in the corners. These take up significant space and make the code larger.
Aztec Code: The Transportation Standard
The **Aztec Code** was designed for efficiency and reliability in challenging conditions. Its key feature is the central "bullseye" finder pattern.
- More Space-Efficient: With no corner patterns, Aztec codes can store more data in a smaller area than a QR code.
- Higher Error Correction: They have a more efficient error correction system, making them readable even if significantly damaged or displayed on a low-quality screen.
- Faster Scanning: The central bullseye allows scanners to locate the code's center instantly, making it faster to read, especially at an angle or when in motion.
These advantages are why many airlines, railways, and ticketing systems rely on Aztec codes for their digital passes.
The Verdict
While a QR Code will work for a simple event ticket, **the Aztec Code is technically superior for high-volume, mission-critical mobile ticketing.**
- If you're creating a ticket for a small event and linking to a webpage, a **QR Code** is fine.
- If you're building a professional ticketing system where scan speed and reliability are paramount (like for public transport), the **Aztec Code** is the better choice.
