Online and Offline QR Codes

QR codes (Quick Response Codes) are two-dimensional barcodes that can contain various information, from text messages to web page links. Depending on whether an internet connection is required for the QR code to work, they can be divided into offline and online QR codes. Offline QR codes can operate without the internet, while online QR codes require an internet connection. These points should be considered if you want to create a digital business card with a QR code.

Basics of QR Code Operation in Offline and Online Modes

Offline QR Codes

Offline QR codes include text, numbers, and Wi-Fi settings. The content is encoded in the QR code during its creation, allowing access to the information without an internet connection. This makes offline QR codes convenient in situations where network access is limited or unavailable.

Examples of Offline QR Codes

  • Text (static). Allows you to display plain text consisting of words, numbers, and special characters. It is one of the most basic types of QR codes.
  • Number (static). This type of QR code allows you to create codes with serial numbers. When scanning a specific QR code, the unique number is displayed on the smartphone without an internet connection.
  • Wi-Fi (static). Allows users to connect to a Wi-Fi network without entering a password. This simplifies the process of connecting to a wireless network for guests and clients.

Online QR Codes

Online QR codes require an internet connection to access the embedded information. They can be either static or dynamic, allowing you to edit the embedded information and track scan statistics.

Examples of Online QR Codes

  • URL QR code (static and dynamic). Converts a website or landing page into a QR code. Dynamic URL codes allow you to edit the link and track scans.
  • Business card (dynamic). A digital alternative to the traditional business card, allowing you to share contact information, including social networks, email, and addresses.
  • File (dynamic). Allows you to create QR codes for various file types, such as MP4, PDF, PNG, and JPEG. When scanned, the file is displayed on the smartphone and can be saved immediately.
  • Social media (dynamic). Contains all your social media platforms in one QR code. Users can access your social media profiles by scanning a single code.
  • H5 editor (dynamic). Allows you to create web pages without paying for a domain.
  • App store QR code (dynamic). Allows scanners to install your app by redirecting them to Google Play Store, Amazon App Store, or Apple App Store.

QR codes provide numerous opportunities for information sharing and audience interaction. Offline QR codes are useful in situations without internet access, while online QR codes offer extended editing and tracking capabilities. The choice of QR code type depends on your needs and usage conditions. Integrating QR codes into your marketing strategy can significantly enhance customer interaction and simplify access to necessary information.
