Although exchanging phone numbers still has a certain charm, social networks are offering young people new ways to swap contact information.

In the latest example, Instagram just debuted Nametag -- a customizable I.D. card that will locate a user’s profile after being “scanned” by another users’ phone.

To scan someone else’s nametag, users can either swipe right into the camera, hover over the nametag and hold down their screens, or enter the camera by tapping “Scan a nametag” when viewing their own.

Nametags can also be shared through text message, and over other Facebook-owned apps like WhatsApp and Facebook itself.

With a focus on fun, Instagram is also encouraging young users personalize their nametags using a range of color and design options, as well as emojis, selfies, and stickers.

Trying to further enmesh itself in users’ college experience, Instagram has also begun testing a school communities feature in the United States.

With the feature, willing users can add a line to their profiles listing their university, class year, and any relevant groups such as major, sports team, and sorority.

Students who’ve added the same university can click to go to a directory listing all the people -- sorted by class year -- who have added that university. There, they can follow and message each other.

It's not exactly cutting-edge technology. Snap, Twitter, and Facebook’s flagship app already let users share accounts via QR codes.

Yet Instagram has demonstrated a knack for popularizing features and technology already offered by other platforms. For example, after taking inspiration from Snap’s Stories, Instagram’s own Stories feature has been a huge success.

More broadly, all eyes are on Instagram as the Facebook unit enters a critical transition period.

It was announced last week that Adam Mosseri will be taking the reins once Instagram cofounders Mike Krieger and Kevin Systrom exit in the near future.

Krieger and Systrom abruptly announced their plans to leave the company they created, the week prior.

Upon the news, analysts and industry watchers said the sudden loss of Instagram’s CEO and Chief Technical Officer was likely bad news for Facebook and its prized unit.

“It’s negative that they won’t be there, as it seems like many of the successes of Instagram in recent years are due to their presence,” Brian Wieser, senior research analyst at Pivotal Research Group, said recently.
