The exchange
What visitors see when they save your contact — and how their details reach you.
Your card's real work happens in two standing actions on the public page — a save button and an exchange button. The Default look sets them in a bar at the bottom as "Save contact" and "Exchange"; every look words and places the pair its own way — "Save my card" and "Exchange cards" on Letterhead, plain "Save" and "Hand over your card" on Mohur. Between them they turn a scan into a two-way introduction, in the browser they scanned with, no app to install.
They save you first
The save button downloads your details as a vCard, a .vcf file that drops straight into their phone book: your name, number, email, tagline as the job title, photo and your card's link, spelled right, no typing.
Then the sheet appears
A moment after they save — or once they read to the bottom of your card, having been on it at least five seconds — a sheet titled "Exchange cards" slides up and offers to send their details back. It asks for little: "Name" and "Mobile number" are required, "E-mail" is optional, and an "Add a message" link reveals a "Message" box. The country code comes pre-selected for wherever they are. The button says "Send my details"; beneath it, a plain promise — "We don't sell your data."
What sending does
Three things, in order. Your vCard downloads again, so even a visitor who skipped the save leaves with your details. A prompt appears with one button — "Get your own eKard". And their details land on that card's Contacts tab with an email on its way to you; the course on your contacts takes it from there. A visitor who left an email address also gets a confirmation in their inbox, with your contact ready to download later.
Once per person, never for you
A visitor who has sent details once is not prompted again in that browser — the sheet returns only if they tap the exchange button themselves. And the sheet never opens on your own preview or owner view, so to watch it as visitors do, open your public link in a browser you haven't submitted from.
Rather not prompt anyone? A switch in Settings retires the popup and leaves a plain save button in its place — the course on Kard settings has the switch.
