Instagram's new 'profile card' turns social networking into a professional networking site for freelancers, content creators, and small business owners.

Instagram has introduced several major changes and updates during the last couple of months -- including new features and privacy protections.

Today, the social site announced profile cards: Users no longer need to type in handle names to find a mutual or new connection; now you can set up a profile card that makes you easily findable with a custom QR code.

The new feature is not unlike the way that digital payment apps, such as Venmo and Cash App, enable their users to share profiles. Instagram's version is a two-sided profile card with one side for the scannable QR code and the other side featuring your IG handle, profile picture, short bio, and a song of your choice.

Instagram compares the new update to the digital version of a business card that you can design to house contact links and showcase your bio "in one sleek digital package." It's a great way to network and "make new connections," Instagram added, and -- by adding a favorite song -- to attract new friends with similar interests.

This upgrade will be helpful for content creators, freelancers, and small businesses, but it's not so obvious how it can be helpful for users who use Instagram as just a social media platform -- other than further professionalizing casual interactions. Ultimately, this speaks to how many social media platforms are encouraging users to develop their personal brands.
