Each person now carries their certifications on their phone. The wallet shows each one and when it runs out, so the card is there at the gate or in the cab.
A person's QR code opens their wallet in the app. It says "you" for your own, and links to the full record.
On the web, the Certifications screen shows how many people hold each one, how many are expiring and how many have run out.
