What is the use of QR code for an Instagram account?
First, it allows you to speed up the process of searching the user, because you do not need to manually enter the nickname. You just need to scan the QR code and the user's page will open automatically.
Secondly, this feature is very convenient for store accounts, because it allows you to quickly open a product catalog.
Businesses can create a QR code and print it on products, signs, or menus, which increase customer engagement.
