1. Choose details that are useful and public
Start with your name and add a work phone, email, company or website where useful. An address and note are optional. Do not put private details in a code intended for public distribution.
Data is inside the image and is not encrypted. A person can keep a copy even if an optional saved project later becomes unavailable.
2. Generate the contact code
Open the free vCard QR generator, enter the fields and inspect the preview. Shorter data generally produces a less dense symbol, so avoid adding a long biography to the note.
The current generator encodes vCard 3.0 and exports QR artwork as PNG or SVG. If your task specifically requires a .vcf file to import into a contact application, do not mistake the image download for that file format.
3. Test what the phone will save
Scan the downloaded artwork on iPhone and Android using compatible readers. Inspect the proposed name, telephone number and email before saving a test contact. Different camera and contacts apps can display different prompts.
Check international phone formatting, accents, non-Latin names and line breaks in your actual data. A QR that decodes as text may still be handled differently by a particular contacts app.
4. Put it on a visiting card
Use the QR image in your own design or open the printable business card tool. Preserve a light clear margin and print a sample at the intended size.
The stored contact fields do not update after printing. When details change, make a new code. A hosted, editable digital profile is a different product capability from this static vCard tool.
