QR Code Types Explained: Static vs Dynamic, URL, vCard & More

QR codes are everywhere—restaurant menus, business cards, product packaging, event tickets, and marketing materials. But did you know there are different types of QR codes designed for specific purposes?

In this comprehensive guide, we'll explore the different QR code types, explain the crucial difference between static and dynamic codes, and help you choose the right type for your needs.

What is a QR Code?

A QR (Quick Response) code is a two-dimensional barcode that stores information in a pattern of black and white squares. Unlike traditional barcodes that store data horizontally, QR codes store data both horizontally and vertically, allowing them to hold significantly more information.

When scanned with a smartphone camera or QR reader app, the code is decoded and the embedded action is triggered—opening a website, displaying text, connecting to WiFi, or initiating other actions.

📊 QR Code Capacity

A single QR code can store up to: 7,089 numeric characters or 4,296 alphanumeric characters or 2,953 bytes of binary data. However, more data means a denser, harder-to-scan code.

Static vs Dynamic QR Codes

The most fundamental distinction in QR codes is between static and dynamic codes. Understanding this difference is crucial for choosing the right solution.

Feature	Static QR Code	Dynamic QR Code
Content	Fixed, cannot be changed	Can be updated anytime
Data Storage	Data encoded directly in code	Points to redirect URL
Code Size	Larger (more data = denser)	Smaller, consistent size
Analytics	No tracking available	Scan tracking & analytics
Cost	Free	Usually subscription-based
Best For	Permanent content	Marketing, campaigns

When to Use Static QR Codes

Personal use (sharing contact info, WiFi passwords)
Content that never changes (permanent URLs, fixed information)
One-time events or materials
When analytics aren't needed
Budget-conscious projects

When to Use Dynamic QR Codes

Marketing campaigns (need to track performance)
Printed materials where content might change
A/B testing different destinations
