Where it works
One number, four jobs. The difference is the buttons on the profile, not the look.
Personal network
After a meeting the card taps the phone. Phone, Telegram, portfolio — instead of paper.
Sales
A shop or a salon: prices, a booking, a pay link. Stats show which button works.
A team
Company seats belong to the firm, not the person. Somebody leaves — the seat comes back.
An event
A card and a QR on the stand. Later the cabinet shows which day and which button started the conversation.
