The wallet ecosystem is still really varied at the moment. Our implementation is unlinkable. So an issuer cannot track where you use the attribute. And a verifier cannot see that you've used the same attribute multiple times with their system. This is great for privacy and tracking protection, but not so great for other things. For example, people sending their QR codes to other people with the correct attribute (like maybe an underage person sending an 18+ check to an adult), is hard to solve for because they are unlinkable.

Most systems right now have you load data in your phone. Then when a check happens, you scan a QR code. You then get a screen on your phone saying X wants to know Y and Z about you, do you want to share this information? Then you just choose yes or no.

For your social media example. You would just get a QR code on your pc, then pull out your phone, scan and verify, then start browsing social media on your pc.
