Contact channels
Eleven 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. Tick, fill the field that appears, press "Update Kard", and the channel is live. Untick a chip and its field folds away again.
The eleven, by name: Phone, WhatsApp, Email, Instagram, Google Business, LinkedIn, 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 four network links must also be on their own network, because a visitor who taps the LinkedIn icon expects LinkedIn: LinkedIn on linkedin.com (or a lnkd.in short link), YouTube on youtube.com or youtu.be, Facebook on facebook.com, fb.com or fb.me, and Google Business on Google: a Google Maps link (maps.app.goo.gl, google.com/maps), your Business Profile's g.page link, or a g.co or share.google link. Anything else comes back with the field marked, saying where the link belongs. Website takes any address.
Google reviews
For a shop, salon, clinic or any business on Google Maps: the Google reviews panel, under Get paid, takes your Google review link, and your Kard shows "Review us on Google" in every layout, opening Google's review form for your business in one tap. It isn't your Google Business link (your Maps page): in your Google Business Profile, choose "Ask for reviews" (on business.google.com: Read reviews, then Get more reviews) and copy the link it gives you. It starts with https://g.page/r/ and ends in /review; a search.google.com/local/writereview link works too. A Maps page's link, a Google Maps share link (maps.app.goo.gl, which can open your Maps page instead of the review form), or a link to another site, comes back saying why. The same link prints as a review card for your counter: Print your card.
Email, and getting paid
Email takes the address you want visitors writing to — the inbox that truly gets read. Ways to get paid (UPI, PayPal, Venmo, Cash App, Pix, IBAN, Zelle) have their own panel under this one, Get paid: Get paid from your Kard covers it.
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 eleven. Four channels you actually answer beat eleven you don't — a chip ticked next month joins the card without disturbing the rest.
