Cards printed once, details edited after
A hosted profile per person with a code on the card. Change the phone number, the job title or the photograph and every card already in somebody's wallet is up to date.
What the person scanning gets
A page with the name, role, photo, phone, email, address and links, and a button that saves it straight to their contacts as a vCard — which is the part that matters, because a card that stays in a browser tab is a card that gets closed.
One per person, managed centrally
On a team plan each person gets a card, and an admin can edit any of them. When somebody leaves, their card is edited or retired in one place rather than being a page nobody remembers owning.
What you learn
How many times each person's card was scanned and where — useful after a conference, and the only honest way to find out whether the cards were worth printing.
