Scan

Point a camera at this. It carries the card, not a link to the card, so it works with the network off.

Most phone cameras read this without an app: open the camera, hold it steady, and the contact appears as a prompt. The code contains a vCard 4.0 record with the name, role, organisation, mobile number, email, website and city. Nothing is fetched, so nothing is logged and it works in a basement.

If the camera will not read it

How it is drawn

Encoded during the build and written into this page as vector paths. There is no image request, no generator service and no script: the reading path here ships zero bytes of JavaScript, and a QR code is one of the few things that can still be produced under that constraint without giving anything up.

Version 17, 85 by 85 modules, error correction level M. The white background is painted by the drawing rather than inherited from the page, in both colour schemes, because an inverted code is out of specification and older scanners return nothing when they meet one. The short address is mosthofaimran.com/scan.
