## What is Invisible Witness?

Invisible Witness turns an authorized user's phone into a secure key for Invisible Witness gate hardware. Using the same encrypted HMAC challenge-and-response as our Bluetooth key fob, the app lets authorized personnel open over Bluetooth LE—no separate fob to carry, lose, or replace.

Built for property owners, contractors, security teams, adventure groups, and site staff who need reliable, accountable access to gated locations.

WHAT YOU CAN DO
• Open nearby gates — Scan for in-range Invisible Witness gates and open the ones you're approved for.
• See your access at a glance — Your approved gates, your access permissions, and registration status on one screen.
• Stay informed — Read system advisories and safety notices from the gate owner.

SECURITY
• A cryptographic HMAC challenge/response runs on every open

ACCESS IS RESTRICTED
Invisible Witness is a closed registration, invitation-based system. Opening a gate requires:
• An approved membership with your organization, 
• Registration code (contact the gate owner), and
• Bluetooth proximity to physical Invisible Witness gate hardware installed at owner sites.
Without approval and nearby hardware, the app still shows your profile and advisories, but won't find or open gates.

PRIVACY
The app does not collect, store, or share your location. See our privacy policy for details.

Invisible Witness gate hardware and an approved account are required. Contact your organization's administrator for access.
