Barcodes helped create the first bridge between physical objects and digital systems. But industrial automation, Physical AI, authentication, and machine-readable environments now require more than printed data carriers. They require physical identity infrastructure that can resolve specific objects, connect them to trusted digital records, and support reliable action.

Machine-readable codes created connectivity between physical objects and digital systems, but connectivity alone does not create trust. As Physical AI expands into real-world environments, reliable identity infrastructure becomes essential for verifying authenticity, enabling secure interaction, and ensuring that physical systems can be trusted at scale.
