QR Codes

A QR Code is a two-dimensional barcode that can encode arbitrary binary data.

Stick one on a physical object encoding a link to a page that can be configured to 301 to arbitrary URLs (e.g. https://www.noisebridge.net/qr/07A72C23A7), and you get a system for hardlinking physical objects into cyberspace.
