A vCard is the standard file format for an electronic contact card. It is saved with a .vcf extension, travels as plain text under the MIME type text/vcard, and holds one person’s name, phone numbers, email addresses, employer, job title, postal address, website, and optionally a photo — every line wrapped between BEGIN:VCARD and END:VCARD. Because every phone, mail client, and CRM on the market can read one, a .vcf is what almost every “save to contacts” button actually hands over, including the one behind a QR-code business card.

This guide is about that file — not the trading card game that shares the name. What is inside a .vcf, how the three living versions of the format differ, why a contact sometimes arrives without the photo or the job title, and what a QR code can and cannot carry.

To add your digital business card to your email signature, copy your card’s permanent link and paste it into your mail client’s signature editor: in Gmail, Settings → See all settings → Signature; in new Outlook and Outlook on the web, Settings → Accounts → Signatures; in Apple Mail, Mail → Settings → Signatures. Add the link as a short line of text (“View my digital business card”), attach it to a button-style image, or place a small QR code next to it — then save and send yourself a test email. The person who receives it needs no app: your card opens in any browser. To send the card without a signature, paste the same link into the body of any email.

That one-time setup turns your busiest channel into a card rack. An estimated 376 billion emails were sent and received daily in 2025, projected to reach 424 billion by 2028, according to Statista — and a long-standing Radicati Group estimate, cited by Campaign Monitor, puts the average business user at about 121 of them every day. You’re already sending the emails. The signature just makes every one of them carry your card.

To create a digital business card on Android, install a card platform’s app from Google Play — or open the platform in Chrome, which builds the same card on the same account. Enter your name, role, photo, and the ways to reach you, and the card publishes to a permanent link with its own QR code. Drop the card into Google Wallet so the QR waits one swipe away, then pass it on by QR scan, by link, or through the Android share sheet. Whoever receives it installs nothing and signs up for nothing — any phone with a browser can open it.

Android gives you more company than any other platform on earth: 68.36% of the worldwide mobile-OS market runs Android as of July 2026, and even in the iPhone-leaning United States it still powers 40.39% of phones. Yet almost every card-app how-to is written next to an App Store screenshot. This one isn’t: it covers the Google Play install, the Google Wallet pass, and the Android share sheet, in that order.

To create a digital business card on your iPhone, download a card platform’s app from the App Store (or open the platform in Safari), add your name, job title, photo, and contact details — your card goes live at a permanent link with a QR code. Add that card to Apple Wallet so it sits a side-button double-click from your lock screen, then share it with a QR scan, an AirDrop, or the share sheet. The person receiving it needs no app, no account, and no iPhone.

If you’re doing this on an iPhone, you’re in good company: iOS holds 58.35% of the US mobile-OS market as of June 2026, so for most American professionals the iPhone isn’t just where the card gets shared — it’s where the whole card gets made.
