What is a QR Code?
QR stands for Quick Response. Unlike a barcode that stores data in one dimension, a QR code uses a grid pattern to pack in far more information. Any smartphone camera can read one instantly.
📊 Barcode
Reads left to right only. Holds up to ~20 digits. Used on retail products.
⬛ QR Code
Reads in two directions. Stores URLs, text, contacts — thousands of characters.

Step 3 — Download

Tips for Better QR Codes
Error Correction Level
QR codes can recover from partial damage thanks to built-in error correction.
| Level | Recovery | Best for |
|---|---|---|
| L (Low) | 7% | Digital use only |
| M (Medium) | 15% | General use |
| Q | 25% | Light logo overlay |
| H (High) | 30% | Logo in center, outdoor printing |
If you plan to put a logo in the middle, choose Level H so the hidden area can still be decoded.
Color Rules
- Light background + dark QR = standard, most reliable
- Inverted (dark background + light QR) works, but some older readers struggle
- Low contrast between foreground and background is the most common cause of scan failures
