PHP Extension Requires Chilkat v11.7.0+

Create a vCard (Contact) QR Code

See more QR Code Examples

Demonstrates a QR code that adds a contact to a phone when scanned. The text is a vCard, the standard format for contact details: lines between BEGIN:VCARD and END:VCARD, each ending with CRLF. A vCard is fairly long, so the symbol is larger than one holding a web address. Leave out the fields that are not needed to keep it small. PHP Extension
