A vCard QR code isn't a link to a database somewhere that looks up your details — it's the details themselves, encoded directly into the pattern. Understanding that distinction explains why it works offline, why it updates instantly as you type, and why it can only hold so much information.
What's Actually Encoded Inside the QR Code
Underneath the visual pattern, a vCard QR code contains plain text written in the standard vCard format — a block starting with BEGIN:VCARD, followed by lines like N: (name), FN: (formatted full name), ORG: (company), TEL: (phone), EMAIL:, and URL:, and ending with END:VCARD. That entire block of text is what gets encoded into the QR pattern — there's no server involved, and no lookup happens when it's scanned. Whatever you type into the form is exactly what ends up baked into the code.
What Happens the Instant Your Phone Scans It
Modern camera apps recognize the vCard text format the moment they decode a QR code's contents, without needing a dedicated scanner app. Recognizing the BEGIN:VCARD structure triggers the phone's native "Add Contact" screen, already pre-filled with whatever fields were included — ready to save to your address book with a single tap, the same as if you'd typed the details in by hand.
Which Fields Are Required (and Why So Few)
Only a name is required to generate a working vCard QR code — everything else, including phone, email, company, and website, is optional and only appears in the encoded data if you actually fill it in. Keeping unused fields out of the vCard also keeps the QR code itself simpler and denser with less data, which in practice tends to make it easier for a camera to scan reliably.
Where a vCard QR Code Is Actually Useful
Because the whole point is letting someone save your details without typing anything, a vCard QR code works well anywhere a person only has a moment to capture your contact info — printed on a physical business card, embedded in an email signature, or displayed on a conference badge. In every case, the appeal is the same: one scan replaces manually typing a name, number, and email into a new contact entry.

FAQ
What happens when someone scans this? This QR code encodes your details in the standard vCard format that phones recognize automatically — scanning it prompts an "Add Contact" screen pre-filled with your name, phone, email, and other details, ready to save with one tap.
Which fields are required? Only a name is required — everything else (phone, email, company, website, address) is optional and only included in the QR code if you fill it in.
Is my information sent anywhere when I generate this? No — the QR code is generated entirely in your browser, so nothing you enter is ever sent to a server.
Will this work with any phone's camera? Most modern iPhone and Android camera apps recognize vCard QR codes directly. Older devices may need a separate QR scanner app instead of the native camera.
