QR code for digital business card: how to create a vCard that saves itself to the address book

The vCard format (.vcf extension) is the universal standard for exchanging contact data between systems: iOS, Android, Outlook, Gmail and any address book understand it. When you encode a vCard in a QR, the phone recognises the format on scanning and directly launches the 'Save contact' dialogue.

This is different from a QR that points to a URL. A URL QR takes the user to a website where they can see the contact data, but saving it to the address book requires a manual step. With a vCard QR, the process is: 1. The contact opens the phone camera 2. Points it at the QR 3. The phone shows: Save contact: First Last? 4. The contact taps Accept 5. The contact is saved in the address book with all the data

No typing, no copying, no going through any website.

In the vCard QR generator at codigo-qr.es you can create the QR with all standard fields: name, company, title, phone, email, website and address.

The vCard format accepts dozens of fields, but on a business card you need to choose those the contact actually uses when saving a number.

Required fields:
• First name and surname
• Phone (mobile preferred, with international prefix: +44 for UK, +1 for US)
• Email

Recommended fields:
• Company or organisation
• Title or role
• Personal or company website URL

Optional fields depending on context:
• Postal address: useful for shops, offices, clinics. Less relevant for freelancers or sales reps who travel.
• Second phone (office landline)
• Social networks: LinkedIn, Twitter. Not all vCard readers display them correctly, but modern iOS and Android do process them.
• Profile photo: the vCard format accepts a base64 image. It adds weight to the QR, so only use it if the QR is large enough (minimum 3.5 x 3.5 cm on a card).

Format tip: phone in E.164 format (+44712345678, no spaces or hyphens) guarantees the phone recognises it correctly in any country.

This difference defines when to use each option.

Static vCard QR: The contact data is encoded directly inside the QR. When the user scans it, the phone reads the vCard without needing an internet connection. Works on the Underground, on a plane, anywhere without signal.

The problem: if you change your phone number, company or email, you have to generate a new QR and reprint the card. All old card stock will have outdated data.

Dynamic vCard landing page: The QR points to a URL that loads a page with your contact profile and a .vcf download button. The user taps the button and the phone saves the contact. If you update the data in the dashboard, the next scan downloads the new data.

Requires an internet connection to work. And the process has one more step: the user arrives at the page, taps the download button, saves the .vcf. Not as direct as the static vCard, but editable.

Which to choose?
• If your data is unlikely to change soon (established freelancer, stable company), the static vCard is more direct and works without internet.
• If you change company, number or website frequently, the dynamic landing page avoids reprinting cards every time.

The vCard QR does not have to live only on the paper card. There are four media where it works well.

Physical card: The back of the card is the standard location. Minimum size: 2 x 2 cm for reading at 15-20 cm. Add a short text below the QR: 'Save my contact' or 'Add to your address book'. Without that text, many contacts do not realise they can scan it.

Email signature: You can embed the QR as an image in your email signature. Not all email clients show images by default, but when they do, the contact can scan the QR from their computer screen with their phone. Minimum size for screen: 150 x 150 pixels.

LinkedIn profile: LinkedIn lets you add an image in the 'Featured' section or in articles. You can put the vCard QR in that section with the text 'Save my direct contact'. Works especially well for contacts who reach your profile but do not formally connect with you.

Presentations and speaking materials: If you give talks or presentations, a final slide with a large QR (8 x 8 cm or more on screen) lets the audience save your contact while you finish the session. More effective than asking them to note down a URL.
