QRT Codes

QRT Codes is a reader for artworks whose code is entirely contained within the data stored inside a QR code.

Scanning a data QR code with a normal camera usually will not open the data website. QRT Codes scans the QR, reads the embedded data, and opens it locally.

Supported format:

data:text/html,<percent-encoded html>

Also supported:

data:text/html;base64,<base64 html>

To make one: write a tiny standalone HTML file, encode the HTML as percent-encoded text or base64, prefix it with one of the formats above, then put the full string into a QR code.

The HTML should not depend on external files. The artwork is meant to live entirely inside the QR.
