A vCard QR Code is a two-dimensional barcode that encodes contact information in the standardized vCard (electronic business card) format. When someone scans the QR code with their smartphone camera, their device automatically recognizes the vCard data and prompts them to save the contact directly to their address book — no typing required. It's the fastest way to share your professional or personal contact details in person, on business cards, email signatures, or marketing materials.

Our generator works entirely in your browser. You fill in your contact details — name, phone, email, company, website, and address — and the tool instantly constructs a valid vCard 3.0 formatted string. This string is then encoded into a QR code using client-side technology. The QR code updates in real-time as you type. You can download the QR code as a PNG image for printing or embedding. No data is ever sent to any server; your contact information stays private on your device.

You can include a wide range of contact fields: first and last name, phone number, email address, company name, job title, website URL, full street address (street, city, state, ZIP, country), and a personal note. The vCard 3.0 standard supports many additional fields like multiple phone numbers, social profiles, and photos. Our tool focuses on the most commonly used fields for quick and effective contact sharing. All fields except the name are optional — you control exactly what gets shared.

Yes. Modern iOS devices (iPhone running iOS 11+) and Android devices (Android 8+) can natively scan QR codes using the built-in camera app and automatically recognize vCard data. When scanned, the phone displays a "Add to Contacts" prompt. For older devices, free QR scanner apps are available. The vCard 3.0 format we use is universally supported across all major contact management systems including Apple Contacts, Google Contacts, Microsoft Outlook, and more.

Absolutely. vCard QR Codes are widely used in professional settings: printed on business cards, added to email signatures, displayed at conference booths, included in marketing brochures, and even on product packaging. They eliminate the friction of manual contact entry and reduce errors. Many professionals report higher contact retention rates when using QR codes at networking events. You can also customize the QR code size and error correction level to ensure reliable scanning in various conditions.

Scanning is simple: iPhone: Open the Camera app and point it at the QR code. A yellow notification banner appears — tap it to preview and save the contact. Android: Open the Camera app (or Google Lens) and point at the QR code. Tap the pop-up to save the contact. Tip: Ensure good lighting and hold the phone steady for best results. The QR code should fill about 50-70% of the camera frame for optimal scanning distance.

vCard 3.0 (also known as vCard v3) is the most widely supported version today. Compared to vCard 2.1, it offers better international character support through UTF-8 encoding, improved handling of multi-line fields, and a more robust structured format. vCard 2.1 is older and uses quoted-printable encoding which can cause issues with non-ASCII characters. Our generator uses vCard 3.0 by default for maximum compatibility across all modern devices and contact applications.

QR codes themselves do not expire. The vCard data is permanently encoded into the QR code's pattern. As long as the QR code image remains intact and scannable (not physically damaged beyond the error correction threshold), it will work indefinitely. However, the contact information it contains may become outdated — so if your phone number or email changes, you'll need to generate a new QR code. For printed materials like business cards, consider generating a new QR code whenever your contact details change.

Yes, completely. Our vCard QR Code Generator runs entirely on your device (client-side). The contact information you enter never leaves your browser — it is not uploaded to any server, not stored in any database, and not transmitted over the internet. The QR code is generated locally using JavaScript. The only data that gets "exposed" is what someone scans from the QR code itself, which is exactly the information you choose to include. You have full control over which fields to share.

No, QR codes are static — once generated, the encoded data cannot be changed. If you need to update the contact information, you must regenerate the QR code with the new details. This is why we recommend using our tool's "Load Sample" feature to test different configurations before finalizing. For dynamic QR codes (which can be updated after printing), you would need a third-party service that hosts a redirect URL, but those typically require subscriptions and raise privacy concerns.
