Scan to add contacts in WhatsApp
Gone are the days when we had to manually add up a contact in WhatsApp which was a bit tiresome and not to mention but yes time-taking as well. WhatsApp has introduced a new feature which makes it a tonne easier to do that. You can scan the WhatsApp bar code of another person to add it up quickly to your contacts. You would see a scanner icon in your contact list as shown below.
Once you click it. It gives you two sections. One would contain your WhatsApp bar code and the other would be a scanner.
If you do not have these options yet, you might have to update it and get the latest version.
