New technology is going slow nowadays and what everyone is doing now is just copying others. Like Twitter copying Snapchat’s QR codes. Twitter added a new QR code feature to its apps that allows you to follow other users by scanning QR codes linked to their profiles.
It plainly works just like Snapchat. Just pull up the new in-app camera to scan another user’s code and it brings up a preview of their profile in which you can follow them there and then. For now it is somewhat hidden in both iOS and Android apps as you’ll have to navigate through the in-app settings to find your code.
But Twitter didn’t manage to copy everything from Snapchat as you can’t customize your QR code on Twitter, it just displays your profile picture.
The feature is a little bit buggy now. But for some, it’s a welcome feature to add to the app.
