Use cases
Supported data types in QR codes
This application supports such types of data as: plain text, email address, link, phone number, SMS message, contact(VCard, MeCard), geolocation, Wifi connection, and calendar event.
Pre-generated QR codes for testing are located in the test-qr-codes directory. A website was used to generate them https://qrcode.tec-it.com/ru/Raw/.
Main use cases
Scanning the code
Point the camera at the code and click the "Process" button. If there is data to process and a handler, the "Show" button will be active on the next page.
Qr Code Generation
To generate code, click the "plus" button in the header panel.
