Launch the Camera and point it towards any QR code. I tried to scan the same code using the ZXing Barcode Scanner, and it only works when I turn on "Use auto focus", "No continuous focus", "No exposure". On my Android Whatsapp, I'm able to get to the point where the scanner is active, and the green scan bar goes up and down, but it never manages to capture the QR code on my computer screen.

In addition to this, in the smart mobile version, each and every one of the gadgets connected to the account is listed, such as the date and time of the last session. You need a Webserver supporting Web sockets. Throughout development, the user must use the WhatsApp app with their account logged in. You need to know basics of WebSockets (JavaScript)Ģ).
