Link, QR Code or Wallet Pass? The Best Way to Share Your Digital Business Card
| Technology | Lets Connect
One digital profile, several ways to share it. Compare the link, the QR code, email signatures, wallet passes and text messages — and learn when each works best.
A digital business card is a single online profile — and the point of it is that you can share that one profile in whichever way suits the moment: a direct link, a QR code, an email signature, a wallet pass, or a quick text or WhatsApp message. None of these is "the" technology; they're just different doors into the same room. This guide compares them so you know which to reach for.
If you want the short version, jump straight to our online business cards or the software-only digital business card — every profile supports all the sharing methods below.
The five ways to share your card
1. The direct link. Every profile has its own URL. Paste it into a message, a bio, a proposal or a signature and one click opens your full profile. 2. The QR code. Every profile automatically generates a QR code that points to the same link. Print it, add it to a poster, a stand, packaging or a slide deck, and anyone with a phone camera can scan it. 3. The email signature. Add your card link (or a small clickable badge) to your email footer so every message you send doubles as an introduction. 4. The wallet pass. Save your profile to Apple Wallet or Google Wallet so it's on your lock screen and ready to show, even offline. 5. Text or WhatsApp. Send the link directly in a message — the fastest option when you've just met someone and want to follow up before you've even left the room.Side-by-side comparison
Method | Best for | Needs an app? | Works at a distance?
Direct link | DMs, follow-up emails, bios | No | N/A
QR code | Posters, stands, packaging, slides | No (native camera) | Yes
Email signature | Every email you already send | No | N/A
Wallet pass | Lock-screen access, video calls | Apple/Google Wallet | No
Text/WhatsApp | Instant, in-the-moment follow-up | No | N/A
Speed and friction
A QR code scan takes a couple of seconds — mostly the camera focusing. A link sent by text is even faster if the other person already has their phone in hand. In practice, most people end up using two or three of these methods depending on context, and that's exactly how the profile is designed to be used.
Reach and compatibility
Every method above works on any modern smartphone with no app install required. QR codes need a camera (universal on phones made in the last decade); links work in any browser or messaging app; wallet passes need Apple Wallet or Google Wallet, both pre-installed on their respective platforms.
When to use each
- Networking events — QR code on a stand or lanyard, plus a quick text follow-up
- Sales meetings — link in your follow-up email or a wallet pass shown on your phone
- Social media bios — direct link
- Print materials, posters, packaging — QR code
- Every email you send — link in your signature
- Google review stands and review stickers — QR code, since it works at a glance without any interaction
For those exact situations we make dedicated QR review cards and stands built around the QR code method.
Security and privacy
Whichever method someone uses, they only ever reach the same public profile — your name, role, links and contact details. No sensitive data is ever exposed through a link, QR code, wallet pass or text message.

Frequently Asked Questions
Do I need different tools for the link, the QR code and the wallet pass?
No. They're all generated automatically from the same profile the moment you set it up — there's nothing extra to configure.
Which method should I lead with?
For in-person meetings, a QR code or a quick text works best. For anything remote, send the direct link.
Can I use all the sharing methods on the same card?
Yes, and it's the recommended setup. Every Online Business Cards profile includes a link, a QR code, wallet-pass support, and easy sharing by text or email from day one.
Is a link or QR code more secure?
Both are equally secure for sharing a public profile — the payload is always just a URL to your profile page, never sensitive data.
Do these methods work on older phones?
Yes. Links and QR codes work on virtually any smartphone with a camera and a browser, which covers the vast majority of devices in use today.
The bottom line
You don't have to choose one method. Use the link for messages and bios, the QR code for anything printed or displayed, the wallet pass for lock-screen access, and a quick text when you've just met someone. Start with an online business card — you'll get every sharing method on the same profile with one dashboard to manage it.
