Digital Business Cards: What to Include and What to Leave Out

A digital business card solves the one problem paper cards can't: the contact lands straight in the other person's phone. The moment someone scans your QR code and the 'Save contact' prompt appears, you've skipped the 'let me type your email later' step where most paper cards die. But a digital card only works if the data behind it is structured and complete.

The must-haves

• Name and job title — what you do, not just who you are.
• Company and a one-line description — context for the conversation.
• Phone, email, and website — the three fields everyone actually uses.
• Location (city is enough) — it matters more than you'd think for trust and follow-ups.
• A vCard (.vcf) export — the format Apple Contacts, Google Contacts, and Outlook all import natively.
• A QR code pointing at the card — so the card is shareable in person, on a screen, or on a printed version.

The nice-to-haves

• Social links that matter for your role — LinkedIn for almost everyone; portfolio or GitHub for designers and developers; a booking link if you take meetings.
• Action buttons — call, email, WhatsApp, or 'book a meeting'. Each button removes a step.
• A photo — people remember faces. Keep it a clean headshot, not a crop from a group photo.

What to leave out

• Every social platform — ten icons of platforms you never post on reads as noise. Keep the ones you'd actually want a client to follow.
• Personal details — home address, personal number, and birthday have no place on a business card.
• Huge bios — the card's job is to start the conversation, not to replace it. One line, not a paragraph.
• Low-contrast or tiny text — a QR code that fails to scan, or a name in 8px gray, defeats the entire purpose.

Why vCard version is worth checking

vCard comes in a few versions, and 3.0 and 4.0 aren't fully interchangeable — 4.0 added newer fields and changed some encoding rules, but not every contacts app on every phone parses 4.0 correctly, particularly on older devices or less common Android contact apps. A card that imports perfectly on a recent iPhone can drop fields or fail to import at all on an older Android phone if it's exported strictly as 4.0. Exporting as vCard 3.0 sacrifices a handful of newer fields but is the safer default when you don't know what device the other person is using, which in a networking context is almost always the case.

QR error correction is a size trade-off, not just a technical setting

A QR code carries built-in redundancy so it can still scan even if part of it is damaged, obscured, or poorly printed — but higher error correction achieves that by encoding the same data less efficiently, producing a visually denser code. On a physical business card, printed small, that density matters directly: a high-correction code that's genuinely scan-resistant to smudging and wear needs more physical size to stay reliably scannable than a low-correction code carrying the same data. If the card itself is compact, that's a real design trade-off between how much abuse the code needs to survive and how small it can be printed and still work.

Give people a way in that isn't a scan

Not everyone will scan a QR code in the moment — a camera app that's slow to open, a code that doesn't focus well in bad lighting, or simply someone who'd rather type a short link than fumble with a scanner. A card that only works via QR loses those people entirely. Printing a short, memorable URL as plain text alongside the code — something typeable in a few seconds rather than a long generated slug — covers the case the scan doesn't, and costs nothing to include.
