Turn your contact details into a scan-to-save QR code. Anyone who scans it gets your name, phone, email, and company added to their contacts in one tap. Download a PNG or .vcf file — no login, no limits, nothing stored.
Point a phone camera at the code to add the contact.
A vCard drops your number and email into someone's phone — but it can't show you're online or let them message you right now. Pair it with a free Knocket contact page: put your page URL in the website field, and one scan opens live chat, WhatsApp, and a booking button too. Grab your free page →
A vCard (.vcf) is the standard digital business card that every phone understands. Wrap it in a QR code and swapping details becomes instant: no typing a number wrong, no "text me so I have your number", no paper card that ends up in a drawer. One scan and you're saved correctly, first time.
.vcf file to share directly.The code encodes a vCard 3.0 — the format built into iPhone and Android contacts. Phone cameras recognize it automatically and offer "Add to Contacts", no special app required. Everything is generated in your browser, so your details are never uploaded anywhere.
A vCard QR code is great for the one thing it does — saving your details. But be clear about its limits:
If you want a card that can change and lets people actually reach you, put a free Knocket page URL in the website field — update it any time, and turn a saved contact into a live conversation.
Yes — completely free, no login, no limits. Your details are turned into a vCard and QR code entirely in your browser and are never sent to or stored on any server.
On most modern phones, just open the camera and point it at the code — a banner appears offering to add the contact. No special QR app is needed on recent iPhones or Android phones.
A vCard is the universal digital business-card format (file extension .vcf). Both iPhone and Android read it natively, so importing a contact from one is one tap.
You can regenerate a new code any time here, but a code that's already printed is fixed — its data is baked in. If your details change often, encode a Knocket page URL instead and edit the page.
Yes. Everything happens locally in your browser — nothing you type is uploaded, logged, or shared. Close the tab and it's gone.
Usually it's too much data printed too small. Keep fields concise, print the code large enough with a clear margin, and test with a couple of phones before printing in bulk.
Put a free Knocket page behind your card — one link with live chat, WhatsApp, email, and booking that you can update any time.
