A QR code can open a restaurant menu, connect to WiFi, display a vCard, download a PDF or redirect to any URL. Each use case has its own guide.
27 use cases with step-by-step guides
A QR code turns any printed surface into a digital access point. A smartphone camera scans it in under a second and opens a URL, shows a contact, connects to WiFi or downloads a PDF: no typing required.
Businesses use them on menus, storefronts, packaging and posters. Professionals add them to business cards and presentations. Creators put them on social media to group all their links. Any photographable surface can become an access point.

What types of content can a QR code contain?
A QR can hold a URL, plain text, vCard, WiFi credentials, WhatsApp number, email, SMS, PDF or any link. The content type determines what happens when it is scanned.
A QR code does not have to contain a URL. It can hold plain text (an order number, an instruction), WiFi credentials (the phone connects automatically when scanned), a full vCard with name, phone and email, or a WhatsApp prefill with a pre-written message. The type of QR you choose in the generator determines what happens to the user when they scan it.
Can a QR code change its destination after printing?
With a dynamic QR yes: you edit the destination URL from the dashboard and the already-printed QR points to the new link immediately.
Static QR codes have the content baked into the image. If you change the URL, you need to reprint the QR. Dynamic QR codes work like a URL shortener: the QR points to an intermediary that redirects to the real destination. Change the destination from the dashboard and all printed or published QR codes update instantly. They are the right choice for menus, catalogs or any material that changes frequently.
What is the minimum size for a QR code to be scannable?
The recommended minimum size is 2.5 x 2.5 cm for print and 150 x 150 px for screens. Below that, less powerful cameras may fail.
The minimum size depends on the scanning distance and the amount of data encoded. For a business card (scanning distance 15-20 cm), 2.5 x 2.5 cm is enough. For a facade poster (scanning distance 1-2 metres), the QR should be at least 10 x 10 cm. The more data a QR encodes, the denser its image and the more size it needs to be reliable. Using a dynamic QR encodes only a short URL, which produces a more readable QR at a smaller size.
