QR codes come in different versions, depending on their intended use and the type of data stored. A basic distinction is made between static and dynamic QR codes.
1. Static QR codes
With a static QR code, the data is stored directly in the code and cannot be changed later. This type of QR code is suitable for:
- Business cards
- Wi-Fi access data
- Contact details (vCard)
- Text messages or simple URLs
2. Dynamic QR Codes
Dynamic QR Codes link to a URL via which the stored information can be subsequently modified. This makes them particularly flexible. They are often used for the following purposes:
- Marketing campaigns (changing content without a new code)
- Event registrations
- Digital menus
- Tracking and analyzing scanning behavior
3. Special QR Code Types
Depending on the application, there are other specialized QR codes:
- URL QR Code: Links directly to a website.
- Wi-Fi QR Code: Allows automatic connection to a Wi-Fi network.
- vCard QR Code: Contains contact information for quick storage.
- Bitcoin QR Code: Facilitates crypto transactions by displaying a wallet address.
- PDF QR Code: Links to a PDF document, e.g. B. an instruction manual.
- Social Media QR Code: Leads directly to a social media profile or company page.
