Contact channels
Twelve channels, toggled with chips. Tick one and its field appears.
The Social links panel of the Kard editor — Kards → Edit Kard — holds the row of chips, and every chip you tick becomes something a visitor can tap: a call, a chat, a follow, a payment. Tick, fill the field that appears, press "Update Kard", and the channel is live. Untick a chip and its field folds away again.
The twelve, by name: Phone, WhatsApp, Email, Instagram, Google Business, LinkedIn, UPI, Website, Telegram, YouTube, Facebook, Twitter. Every one is optional. What a field expects depends on its kind.
Numbers
Phone and WhatsApp use an international phone input with your country already picked, detected from your location. The two are independent — a card can carry WhatsApp without a phone line, or the other way round. Phone is forgiving: any possible number passes. WhatsApp checks harder — it must be a fully valid number before the form will save it.
Fill WhatsApp or Google Business and your Share tab gains "Quick links" — one-tap shortcuts covered in Share your card.
Handles
Instagram, Telegram and Twitter want the bare username — letters, digits, dots and underscores, nothing else. The field already wears the @, and a leading @ you type anyway is stripped automatically. No profile links here; the username alone is the whole entry, and the card turns it into the right link on its own.
Full addresses
Website, LinkedIn, YouTube, Facebook and Google Business are the opposite: each wants the complete web address, https:// (or http://) included. A bare example.com is rejected before the card saves — copy the address out of your browser's address bar and the scheme comes along on its own. Custom links elsewhere on the card follow the same rule; see Custom links.
The other two
Email takes the address you want visitors writing to — the inbox that truly gets read. UPI takes the ID you get paid at and puts a pay link on your public card; amounts, layouts and the visitor's side of it are covered in the course on taking payments with UPI.
Unticking a chip does more than hide its field — the next save permanently clears that value. Untick to hide is also untick to erase. To reword or correct a value, leave the chip ticked and edit the field instead.
On the public page, each layout arranges the same channels its own way — an icon row on one look, ledger rows or machined keys on another. The data is yours; the arrangement belongs to whichever look you pick in Choose a layout.
And there is no need to fill all twelve. Four channels you actually answer beat twelve you don't — a chip ticked next month joins the card without disturbing the rest.
