On Instagram, go to your profile and tap the menu icon, then select "QR Code." Customize the design if desired, then save or share the QR code directly from the app. This code allows others to quickly access and follow your Instagram account by scanning it.
Another way to do it, is use Digiphy to generate your QR codes. Then create a link in bio page using Digiphy, to share more links, videos, sign up forms and more! You can always update the QR code, the redirect URL and the digital experience after the scan in one system using Digiphy.
