WhatsApp Tests New Feature That Lets You Add Contacts Via QR Codes
The feature, which is available in beta on both iOS and Android, can be found in the app’s settings menu, where there are options to display your own code, as well as to scan other people’s. A QR code can also be revoked if it gets shared with someone who you don’t want to have your number.
Once you share your QR code with a new friend, they will be able to scan the code from within WhatsApp and add you easily. Needless to say, when you share your QR code, your phone number will also be shared. To address privacy concerns, WhatsApp gives you the option to reset a QR code an unlimited number of times.
It’s a minor feature, but adding contacts on WhatsApp can be a pain. At the moment, the service relies on you adding a new contact to your phone’s address book, which creates an annoying extra step when you just want to be able to message someone in WhatsApp itself. QR codes are a much more convenient way of adding someone if you’re with them in person, although it won’t make the process too much easier if you’re doing it online.
