The ELAI Chip Bridge lets verifythecard.com, americafirst4us.com, and other ELAI ecosystem websites talk to the chip card in your USB smart-card reader — without opening a localhost network port.

WHAT IT DOES

The extension is a sandboxed Native Messaging bridge between web pages on a small allowlist of origins (verifythecard.com, americafirst4us.com, idregulators.com, idregulars.com, 4pdfs.com) and a local Python helper that talks to your reader via the operating system's PC/SC smart-card subsystem.

When a verifythecard.com page asks "is the chip card in the reader real?", the request flows through the Chrome Native Messaging pipe to the local helper, which runs an ISO 7816-4 SELECT + INTERNAL AUTHENTICATE exchange and returns the result. The chip's private key never leaves the secure element.

WHY USE THE EXTENSION INSTEAD OF A LOCALHOST HELPER?

Earlier ELAI tooling opened a localhost HTTP port to talk to the reader. That works, but it's an attack surface — any tab in any browser can probe it. The Native Messaging architecture eliminates that completely:
