WhatsApp will soon let users add new contacts just by scanning a QR code

WhatsApp will soon let you add new contacts just by scanning a QR code. The Snapchat and Instagram like feature is already available in the latest beta versions for both the Android and iOS platforms. Once available, it will allow users to display their own contact QR code as well as scan other people’s code. The QR code scan feature could also complement WhatsApp Pay.
