Where QR Code Is Used
Product labels linking to your website
Customers scan the label to see product details, reviews, or your store.
Wi-Fi credential labels
Encode Wi-Fi SSID and password — guests scan and connect automatically.
Business cards and vCards
Encode full contact information (name, phone, email, company) in one scannable code.
Restaurant and event menus
Link to a PDF or web menu — no printed menus needed.
Payment links
Link to a payment page or PayPal.me URL for easy in-person payments.
App download links
Link directly to your app on the App Store or Google Play.
When to Use QR Code
- ✓ You need to store a URL, website address, or long string
- ✓ You want customers to scan a label with their phone
- ✓ You're encoding Wi-Fi credentials, a vCard, or payment link
- ✓ Your label is large enough for a 2D code (at least 2cm × 2cm)
When NOT to Use QR Code
- ✗ Logistics and shipping barcodes — warehouse scanners use Code 128, not QR
- ✗ Retail POS systems — use EAN-13 or UPC-A for checkout scanning
- ✗ Very tiny labels — DataMatrix is more space-efficient at small sizes
- ✗ Amazon FBA labels — FNSKU requires Code 128 specifically
