QR Code Ideas: WiFi, Menus, Business Cards, and More

A QR code doesn't "know" what it contains — it's just a way of encoding text so a camera can read it instantly. Whether that text is a URL, a WiFi password, or a contact card is entirely up to what you put in. Here's the exact format for the use cases people actually search for.

WiFi sharing

Instead of a link, encode the network credentials directly using the standard format:

WIFI:T:WPA;S:NetworkName;P:Password;;

Scanning it joins the network immediately on most phones — no typing, no reading a password off a sticky note. Swap in your own network name and password and keep the punctuation exactly as shown.

Restaurant table menus

Just the URL of your digital menu page. Generate it at a larger size (400px+) for table tents or window stickers, since it needs to scan reliably from a short distance in variable lighting.

Business cards

A plain profile link (LinkedIn, portfolio) works, but a vCard link lets the person scanning it save your contact details straight to their phone in one tap, rather than just opening a webpage.

Print ads and packaging

Any landing page URL — but link to something built for the moment someone's already holding a phone (a discount code, a product manual, a signup form), not just your homepage.

One thing to check before printing

Test the code on an actual phone camera before it goes to print — screen previews don't reveal a common failure: too little white space ("quiet zone") around the code makes it unreadable once it's shrunk down for a real product.
