CEO & Co Founder of 𝙝𝙖𝙥𝙥𝙮𝙖𝙥𝙥 solutions My latest partnership is DoorVi™ - A World 1st QR Code Based Door Video Calling which is replacing your doorbells / Intercom with just a QR Code. Any Visitor standing outside your home or business just needs to scan your QR code with their phone to connect with the house owner over a video call. ( they do not need to download the app ) The house owner can see and speak with the visitors from anywhere in the world on their smartphone, for just a small one off lifetime subscription it’s a no brainier.
