The QR code it was already present on WhatsApp, but now the technicians have decided to update it and perform a simple redesign to make it more consistent with the stylistic lines of the application. The way it works, however, remains the same: if you need to get a friend into a group Whatsapp and you are an administrator, just let him scan the QR code and he will have direct access. To use the new QR code, you need to update the application to the latest beta version for Android, the number 126.96.36.199. If you are not yet a beta tester, you can become one by downloading WhatsApp Beta directly from the Google Play Store.
