If you want to connect with your friend on your favourite messaging app, what do you do? Invite via email, phone number, or handle? But what if you just met this person and don’t have this information? Or what if you don’t want to share your own contact info?

The answer is your own personal QR Code. When your new friend scans this with their phone, both of you get connected on the messaging app.

Don’t believe us? Almost all popular messaging apps are already using QR Codes as an authentication feature to add friends.

These QR Codes can be scanned easily with a smartphone. Also see: Integration of Google Lens into the stock camera app to allow QR Code scanning.
