ELAI Chip Bridge
Privacy Policy
What this extension collects, what it sends, and what it persists. Short answer: nothing.
Last updated · June 6, 2026 · Effective from extension v1.0.0
1. Who we are
The ELAI Chip Bridge extension is published by AmericaFirst4Us Inc., the same entity that operates verifythecard.com, americafirst4us.com, idregulators.com, idregulars.com, and 4pdfs.com. Contact: jjloflin@americafirst4us.com.
2. What data the extension handles
The extension handles three message types between web pages and the local Native Messaging host:
ping— liveness check. No card data involved.health— returns the connected chip-card reader's name, its ATR (a public, non-secret identifier), and whether a card is currently inserted.chip-event— runs an ISO 7816-4 SELECT-by-AID + INTERNAL AUTHENTICATE protocol exchange. Returns the raw exchange (AID, ATR, status words, and any card-emitted public response data).
None of this data is your private key, your card number (PAN), or your name. Chip cards refuse to release those over INTERNAL AUTHENTICATE outside a full payment transaction — the chip itself protects them, not us.
3. What we collect and store
Nothing. The extension does not write to chrome.storage, does not use cookies, does not maintain any database, and does not send any data to any remote server (including ours).
Communication happens entirely between:
- Web pages on the allowed origin list (americafirst4us.com, verifythecard.com, idregulators.com, idregulars.com, 4pdfs.com, plus localhost for development)
- The local Native Messaging host (
elai-chip-helper-host.py) that you installed yourself
Both ends of that pipe are local to your computer. The extension has no outbound network access of its own.
4. What we send to third parties
Nothing. No analytics. No telemetry. No crash reporters. No advertising. No remote logging.
5. Permissions and why we need them
nativeMessaging
Required to spawn the local Python host (elai-chip-helper-host.py) that talks to your chip-card reader via the OS PC/SC subsystem. Without this permission, the extension cannot perform its single function.
host_permissions and content_scripts (5 ELAI origins + localhost)
Required so the extension can be reached by web pages on those origins via the externally_connectable API. The allowlist is hard-coded and limited to AmericaFirst4Us Inc.-operated domains.
6. The chip reader and your card data
When you use a website that calls chrome.runtime.sendMessage(..., {type: 'chip-event'}) via this extension, the following information flows briefly through the extension and back to the calling page:
- The card's ATR (a public hardware identifier the card emits when powered)
- The matched AID (e.g.
A0000000031010for Visa Credit/Debit) - The card's SELECT response (a public application identifier block)
- The status word the card returned for INTERNAL AUTHENTICATE
- If the card is a federal credential (PIV/CAC) that signs the challenge, the resulting cryptographic signature over a fresh random challenge
The chip's private key never leaves the secure element. Your PAN, your name, and your magstripe data are not exposed by the ISO 7816-4 commands this extension uses.
7. Children's data
This extension is not directed at children under 13 and we do not knowingly collect data from any user, of any age. (See section 3.)
8. Changes to this policy
If we update this policy, we'll update the "Last updated" date at the top. Material changes will be announced via the Chrome Web Store listing description prior to a new version going live.
9. Your rights
Because we don't collect data, there's nothing for us to delete, correct, or hand back to you. You can verify this by:
- Reading the extension source — it's distributed unminified and the entire codebase is under 500 lines
- Watching outbound network traffic with
lsof -i, Little Snitch, or your firewall of choice — you will see zero traffic from the extension - Uninstalling at any time at
chrome://extensions/; nothing is left behind beyond the local Native Messaging host you installed yourself (which has its own uninstall script)
