A digital business card shares your professional profile through a link, QR code, wallet pass, or text message. No app needed, updates in real time, and works on every phone.

You've probably shared a link before and watched a page open instantly on someone else's phone. That's essentially how a digital business card works — except instead of a random webpage, it's your entire professional profile.

What Is a Digital Business Card?

A digital business card is an online profile that lives at a link you control — no plastic, no printing, nothing to run out of. You share that link however suits the moment: a QR code, a text message, a WhatsApp chat, an email signature, or a wallet pass on someone's phone. Whichever way it arrives, the recipient's browser opens your profile immediately.

Quick answer: Your digital business card is a secure, hosted profile page. You share the link to it — by QR code, message, or wallet pass — and it opens instantly in any browser, on any device, with no app required.

How Sharing Actually Works

  1. You share your link — by displaying a QR code, sending a message, adding it to your email signature, or saving it to Apple Wallet or Google Wallet
  2. The recipient scans or opens the link — a QR code opens the camera-recognised link, a message link opens with one click
  3. Your profile loads in their browser — no app to download, no account to create
  4. They save your details — saved to their contacts in a couple of taps on their screen

The whole exchange takes just a few seconds.

Which Devices Does It Work On?

Every method works on any modern smartphone:

  • QR code: scanned by the native camera app on iPhone and Android — no extra app needed
  • Shared link: opens in any mobile or desktop browser
  • Wallet pass: adds to Apple Wallet or Google Wallet for quick access from the lock screen
  • Email signature: one click from any inbox

Because everything runs through a standard web link, there's no compatibility issue to worry about — old phone or new, iPhone or Android, it just opens.

What Information Can You Share?

Your digital business card profile can include:

  • Full name, job title, and company
  • Click-to-call, email, and WhatsApp buttons
  • Social media profiles — LinkedIn, Instagram, TikTok, and more
  • Portfolio, testimonials, and case studies
  • Booking links (Calendly, HubSpot)
  • Products and services

The best part? You can update any of this information anytime — instantly, and everyone who already has your link or QR code sees the change straight away.

FAQs — How Digital Business Cards Work

How do digital business cards work?

Your profile lives at a link you control. Share it as a QR code, a text or WhatsApp message, an email signature, or a wallet pass — the recipient opens it instantly in their browser, no app needed.

Do I need an app to use a digital business card?

No. Everything works through a standard web browser on any modern smartphone. The recipient just taps or scans and views.

Can I update my card after sharing it?

Yes. Your profile is stored online and can be edited anytime — new job title, new links, new branding — and everyone with your existing link or QR code instantly sees the update.

What if someone doesn't want to scan a QR code?

No problem — every profile also works as a plain shareable link, so you can send it by text, WhatsApp, email, or AirDrop instead.

Is sharing a digital business card safe?
