QR codes are those little square patterns you scan with your phone to pay for coffee, visit a website, or check in at an event.

They're super handy, but did you know there's more than one type? Each QR code has its own strengths, making it perfect for specific jobs.

We'll break down the types of QR codes in a way anyone can understand. Plus, we'll show you how to make your own using our free QR code generator.

How QR Codes Are Grouped

QR codes can be sorted in three main ways: how they're built, what they hold, and how they're used. Here's the rundown:  

1. By Design (Encoding Structure)

This is about how the code is made.  

Stacked Barcodes: Imagine stacking several regular barcodes (like the ones on grocery items) into one.

That's a stacked barcode, like PDF417. They hold more info than a single barcode but less than other QR types. You'll see them on IDs or tickets.  

Matrix Barcodes: These are the square codes with tiny black and white boxes, like QR Code or Data Matrix.

They pack in tons of info and can still work if scratched, making them the most popular choice today.

2. By Content (Static vs. Dynamic)

This is about whether the info can change.  

Static QR Codes: What you see is what you get. Once made, the info, like a website link, is fixed forever. Great for things that won't change, like a business card URL.  

Dynamic QR Codes: These are magic! They link to a short URL you can update anytime.

Change a menu, swap a webpage, whatever you want, without reprinting the code. Perfect for ads or promotions.

3. By Use (Active vs. Passive Scanning)

This is about who scans them.  

Active Scanning: You scan these with your phone, like paying at a store or getting event details. It's all about you taking action.  

Passive Scanning: Machines do the work here, like in factories where QR codes track parts on an assembly line. No human needed!

2D Barcode Types You Should Know

Here are the big players and what they're good at:  

● QR Code: The king of QR codes! It holds lots of data (numbers, text, even emojis) and works even if damaged. Used for payments, websites, and more.  

● Data Matrix: Tiny but mighty. Perfect for small items like electronics or medicine bottles where space is tight.  

● PDF417: A stacked barcode that's a data hog, great for driver's licenses or boarding passes.  

● Aztec Code: Built for speed, often found on train tickets or plane passes.
