People often assume a QR code always opens a website. In reality the square is a container, and what it holds depends entirely on the payload you put inside it. Understanding the main content types helps you pick the right one for the job and avoid the awkward situation where a scan just shows a wall of raw text.
Text, URLs and Email
These three cover most everyday uses:
- Plain text — a short note, a serial number or a coupon code. It needs no internet, so it always resolves;
- URL — the classic choice, opening a browser to a page, form or store;
- Email — pre-fills a "to", subject and body so a scan starts a ready-written message;
- SMS — opens a text message with the number and text already filled in.
Wi-Fi and Network Sharing
A Wi-Fi code stores the network name, password and encryption type. Guests scan it and their phone joins the network automatically — no typing, no spelling mistakes. Keep the password short-ish and rotate the code when you change it.
vCard Business Cards
A vCard holds a person's name, phone, email, company and website in a standard format. Scanning offers to save the contact straight into the address book. It is the cleanest way to hand over details at a conference, and they never expire.
Phone, Location and Payment
For action-oriented uses, the reader can dial or navigate directly:
- Phone — a scan opens the keypad with the number ready to call;
- Location — opens a map pin so people can navigate to a shop or venue;
- Payment — launches a wallet or payment link, covered in our payment QR guide.
Choosing the Right Type
Ask what you want the person to do. If they should look at something, use a URL. If they should message you, use Email or SMS. If they should save or join something, use vCard or Wi-Fi. Matching the type to the action is what makes a scan feel instant instead of confusing. When you are ready, create a QR code free with QR StarCode and switch between all eleven types in one place.
