it is possible to connect the phone camera to take a picture or capture a bar code from d5…?

@Javier_Guerra I do not understand your question! Can you explain what you want to know?

I mean, d5 not have camera and I want to scan the bar code of whatsapp from my laptop …

Sorry but I still do not understand. You want read the barcode with a device that has not have camera? If you do not have camera it is not possible, at least directly, but you can read with a mobile phone and after reading and generate the link you can send or write the link on your watch.
