In May this year, WhatsApp was spotted testing a QR Code shortcut in the app.
Now, another tweet from WhatsApp beta tester WABetaInfo pretty much confirms the feature and hints that it may roll out to end users very soon. This feature was spotted in Android 2.19.189 beta update.
The QR code feature, in typical BBM-style, will allow users to scan the code to add a contact or share their codes to share their own contact details with someone else. This reduces the entire process of jotting down the number and saving it.
Reportedly, users will have an option in the settings of the app to add or remove the shortcut to QR code to their chats. For security, WhatsApp will reportedly also give an option to users to revoke the QR Code at any time replacing it with a new one.
