The Biofire Smart Gun uses status indicators on the front sight and rear display to communicate operational state such as whether the Smart Gun is armed, disarmed, or authenticating. These indicators provide real-time visual feedback about the Smart Gun's current operational state.
Please refer to pages 34-37 of your Product Manual for more information on status indicators, warning states, and the rear display.

The Guardian Biometric Engine
The Guardian Biometric Engine powers the arming and disarming of the Smart Gun by sensing when it has been picked up or put down by a user, and verifying valid biometric data of an authorized user. The Guardian Biometric Engine includes:
- Presence sensors that actively detect when someone is gripping the Smart Gun
- Fingerprint identification and facial recognition systems that independently verify and authenticate an authorized user
- Electronic fire control system
The Smart Gun becomes armed only after the Guardian Biometric Engine is provided with biometrics of an authorized user.
Please refer to The Smart Gun Biometrics article for more information on the Guardian Biometric Engine.
