# QR code content

What a QR code encodes is not always a web address. The **Chose content** list on the generator decides what the scanning phone is handed — a number to call, a message to send, an event to save, a network to join — and each one behaves differently once scanned. Opening a website is only the most familiar of them.

![The Chose content list open on the creation form, offering URL, phone call, email, SMS, location, event, Wi-Fi network, plain text, document, vCard, audio media and custom URL](https://www.unitag.io/documentation/images/qrcodes/en/qr-codes-content.webp)

> Static and dynamic content
>
> A static QR code carries its content inside the pattern: the scanning phone reads it without contacting anyone, it works offline, and nothing about it can change once the code is printed. A dynamic QR code carries a short URL instead — Unitag hosts the content and sends each scan to it, so your reader gets a page they can interact with and you can change what they see at any time. Most contents can be either; the chips under each heading say which resolutions it offers.

#### URL

Available as: Static, Dynamic, Dynamic Pro.

The scan opens a web address in the phone's browser. It is the most common content by far, and as a dynamic QR code it lets you change the destination later and collect scan statistics.

#### Phone call

Available as: Static, Dynamic, Dynamic Pro.

You supply a phone number. The scan opens the phone's dialler with that number filled in, ready to call.

#### SMS

Available as: Static, Dynamic, Dynamic Pro.

You supply a phone number and the body of a message. The scan opens the messaging app with both prepared, so the reader can send it as is or edit it first.

#### Email

Available as: Static, Dynamic, Dynamic Pro.

You supply a recipient, a subject and a body. The scan opens the mail app with the draft ready; the reader can still change it before sending.

#### Event

Available as: Static, Dynamic, Dynamic Pro.

You supply a date, a time and a place. The scan offers to save the event to the phone's calendar, reminder included.

#### Location

Available as: Static, Dynamic, Dynamic Pro.

You supply a latitude and a longitude. The scan drops that point into the phone's usual maps app.

#### Wi-Fi network

Available as: Static, Dynamic, Dynamic Pro.

You supply a network name and its password. The scan connects the phone to that network, without anyone having to read the password aloud.

#### Plain text

Available as: Static, Dynamic, Dynamic Pro.

The QR code carries raw text, shown on screen when scanned. Any message will do, but it cannot be formatted — no bold, no italics, no links.

#### Document

Available as: Dynamic, Dynamic Pro.

The QR code opens a PDF you upload to Unitag, which hosts the file and serves it to whoever scans. The document can be put behind a password, so it only opens for readers you have given it to — useful for a price list, a manual or a contract you would rather not leave open on the web. Because the file is hosted, this content is dynamic only: there is no static version, and you can swap in a new PDF long after the code is printed.

#### vCard classic

Available as: Static, Dynamic, Dynamic Pro.

A business card in a QR code: a name, a role, a company, a phone number and an email, which the scanning phone offers to save straight into its contacts. This is the classic vCard format — it remains here for codes that already depend on it, and it is the gentlest way into sharing a contact with Unitag.

> Beyond the classic vCard
>
> Unitag vCards are a richer version of the same idea: a hosted card you can restyle and edit after the code is printed, with links, buttons and statistics.

#### Audio media

Available as: Dynamic, Dynamic Pro.

The QR code plays an audio clip you upload — a spoken message, a commentary beside an exhibit, the correct pronunciation of a name. The reader hears it in their browser, with nothing to install. Like Document, it is hosted by Unitag and therefore dynamic only, so the clip can be replaced without touching the printed code.
