Instructions for using the TAC app in offline mode to share contact information:

1. Open the TAC app on your device.
2. Select the "Share" option found in the app's menu.
3. Choose the "QR Code Offline" option. This action will generate a QR code that can be scanned without an Internet connection.
4. Show the generated QR code to the person you wish to share your information with.
5. The person will need to scan your QR code using the camera on their device, allowing them to save your contact directly in their address book.

The generated QR code contains all the necessary information of your contact and can be scanned even without an active internet connection. This makes sharing contacts quick and practical, perfect for situations where connectivity is limited.
