Digital business card

A page with your name, what you do, your WhatsApp and your photos, on a link that fits in a bio and a QR code that fits on a sticker. Cadu makes it free in a conversation, and when your number or your service changes, you change it with a message.

What a digital card needs

  1. One tap to reach you on WhatsApp

    A paper visiting card gives the number; a digital one gives the button. Whoever opens your link taps once and is in a chat with you, with nothing to type. That is the one thing the card has to do well. Everything else is there to earn trust before the tap.

  2. What you do, in one line

    "Electrician, house wiring and repairs, covering Pune west." "Home tutor, maths and science, classes 6 to 10." One line a stranger understands in two seconds before deciding to tap. Your name on its own says nothing to someone who does not know you yet.

  3. Proof: photos, services, area

    Three photos of your work, the list of what you do with prices where you can, the areas you cover. That is what turns the card from "a contact" into "the contact". Nothing invented: only what you actually do.

  4. One link for everywhere

    The same address goes in your Instagram bio, your WhatsApp status, your email signature and the post in the neighbourhood group. Unlike a PDF or a picture of a card, it does not get lost, go stale, or need re-sending.

  5. A QR code for paper

    A sticker on the van, the toolbox, the counter, or the back of the paper cards you already carry. Ask Cadu for the QR code and it arrives as an image, ready to print. Whoever points a camera at it opens your card.

  6. New number? One message

    New phone, new service, new area: send it to Cadu and the card changes. The stickers and links already out there keep working, because the address stays the same.

What your customer wants to find

Wants to talk to you now

One tap opens WhatsApp. No copying a number, no saving a contact first.

Wants to know it is really you

Name, photo, what you do and where: enough to trust a stranger.

Wants to find you again

The link stays in the bio and the status. Whoever looked today finds you next week.
