Fill in the name, phone, email, company and address fields — the .vcf preview and QR code update as you type. Then download the .vcf file for emailing or the PNG QR code for printing.
Yes. The file is written as vCard 3.0 with CRLF line endings and properly escaped commas, semicolons and line breaks, which is the format every mainstream contacts app accepts. Download it and open it, or attach it to an email and let the recipient tap it.
No. The QR code encodes your contact details directly inside the pattern — there is no short link, no redirect service and no analytics in the middle. It keeps working forever and nobody logs the scans, which is not true of most 'dynamic' QR services.
Yes, that is the most common use. Download the PNG at a large size and place it at roughly 2 cm square or bigger on the card; because the code is generated at high resolution it stays sharp at print DPI and scans reliably from a phone camera.
