vCard

vCard is a standard format (RFC 6350) for describing contact information such as name, phone number, email address, and postal address in a structured way. When vCard data is stored in a QR code, compatible smartphones and apps can add the scanned contact.

It is used for QR codes printed on business cards and can reduce the effort of manual entry and input errors. A vCard can also include the company name, job title, website URL, social media accounts, and more.

One point to note when printing a vCard QR code on a business card is that if too much information is stored, the version of the QR code goes up and the printed size becomes larger. To fit it within the space of a business card, one approach is to limit it to the essential information (name, phone number, email address, URL) and to post the detailed information on the web page at the URL.
