What happens when someone scans a vCard QR code?

Their phone shows a new-contact screen with your name, numbers, email, company, and address filled in. They tap save and you are in their address book — no app needed, and it works offline because everything lives inside the code.

Should I choose vCard 3.0 or 4.0?

Pick 3.0 unless you have a reason not to — it has the widest scanner support, including older Android phones. 4.0 is the newer standard but a few scanners still mishandle it.

Is my personal information uploaded anywhere?

No. The code is generated entirely in your browser, free with no signup. But remember the details are readable by anyone who scans the code — only include what you would put on a paper business card.

Why is my vCard code so dense?

Every field you fill adds bytes, and more bytes mean smaller squares. If you are printing small, skip optional fields like the full address — a name, number, email, and website scan beautifully.

Can I update my details after printing?

Not with a static code — the details are baked into the squares. If your details change often, encode a URL to a contact page instead, and update the page rather than the code.
