Your link and your name
How share links work, what a name link is, and what changing one does to what you've shared.
The moment a Kard is created, eKard assigns it a link — five random characters, letters and digits, something like ekard.app/k3fp9. It costs nothing, it never expires, and it is already live: anyone who opens it sees your card.
You will find it on the Share tab — the tab you land on when you open a Kard from Kards — in the read-only "Share link" field with its "Copy" button. The QR code on the same tab encodes the same address, so the link and the code always agree. Print it, put it in an email signature, paint it on the shop wall: a random link is a perfectly good permanent address.
A name of your own
Random works; a name is better. A name link — ekard.app/yourname — comes with every paid plan, and you choose it yourself. The course on plans and billing covers what each costs.
Open the Kard, then Settings: Your link is at the top. Type the name you want after ekard.app/, and it's checked as you type — "ekard.app/priya_sharma is free", or why not, in plain words. Save my link puts it live at once, and the page says so. A Kard's link can change 3 times a day: each change draws its QR codes again.
Names are first come, first served — each has exactly one owner. They are 4 to 100 characters of lowercase letters, numbers, dots and underscores, with no spaces or hyphens; capitals fold to lowercase, so ekard.app/Priya and ekard.app/priya are the same address. A few words are kept for eKard's own pages (ekard.app/university, for one), and a team's address or another Kard's old link can't become yours: someone's printed QR codes lead there.
On the free plan, Your link shows the link you have and what a name link would look like, with the way to get one.
A team Kard's link starts as the team's address and its holder's first name: ekard.app/acme/priya. With a team plan, the team's admins choose each team Kard's link in its Settings the same way; its holder sees who to ask. The team's main Kard is the team's address itself, changed in the team's settings.
What a link change touches
A link change — including the day your name replaces the random link you started with — takes effect at once. The old address doesn't die: it sends visitors on to the new one, with whatever followed it (/whatsapp, a document under /files/), so links you've shared and QRs you've printed keep working. Nobody else can take the old link, so that holds for good; the Your link panel lists the old links still leading to your Kard.
eKard handles the digital side on its own: the card's QR image regenerates with the new address, and so does the QR of every document the card carries and the picture chat apps show for your link. The course on your QR code covers when and why QRs regenerate.
A printed QR leans on that redirect from then on. After a link change, download the new QR and use it in your next print run — cards, signage, packaging. Choose your name early, before the print run, and the question never arises.
