A quick guide

Use the number with context

The answer is only useful when you know what it includes and what it leaves out.

How to use it

  1. Enter the contact name and any optional details.
  2. Review the escaped contact payload.
  3. Scan-test before downloading the QR or .vcf file.

Formula

vCard payload = escaped VERSION:3.0 contact fields

The QR and .vcf contain the fields shown in the preview; they do not publish the contact.

Make it concrete

Worked example

A name containing a comma is escaped so contact apps do not split it into another field.
