Long lingering on the sidelines, QR codes, those barcodes that allow for content to be accessed online through the camera on one's smartphone, are currently enjoying a new boost in popularity. One of the latest examples is found on Instagram, which now allows users to generate a QR code that will allow another person to easily access their profile, simply by scanning it with another smartphone.
To access one's own QR code and share it with a contact, you simply need to go to your profile menu and select QR Code. Then all you have to do is show it to a contact who can scan it with their device's camera and thereby discover your account – and, hopefully, become a follower. It's also worth noting that the background of the QR code can even be customised with emojis.
