Part 1 – General

1.1 Summary
A. This section defines requirements for Person Readers, a class of intelligent, AI-driven edge devices providing identity recognition, access authorization, elevator dispatch, intercom communication, visitor processing, and telemetry.

B. Person Readers shall function as identity-centric computing platforms, not simple credential readers, and shall provide consistent behavior across doors, turnstiles, lobbies, elevator kiosks, and elevator cars.

C. Person Readers shall integrate natively with the Physical Security Management Platform and operate autonomously when required.

1.2 Purpose And Intent
A. Replace static card-reader models with multi-modal, high-assurance identity recognition.
B. Reduce friction while increasing security, auditability, and throughput.
C. Enable unified access, elevator dispatch, visitor management, and intercom functionality in a single device.
D. Future-proof buildings through AI-enabled, OTA-updatable edge computing.

1.3 Definitions
• Person Reader: Intelligent edge device performing identity recognition and access actions
