Rekkeh models security as a continuous control chain rather than a single gate check. Every entry is the result of a sequence that produces a verifiable, accountable decision. The chain has six links: 1. **Identity**: Rekkeh establishes who is requesting access using pre-registered visitor details, resident profiles, or kiosk-captured data. 2. **Verification**: The system checks whether the identity matches an active pass, a valid resident status, or an approved event invitation. 3. **Access Decision**: The Access Control Engine evaluates the pass type, expiration, flags, and site policies to produce an allow, deny, or escalate outcome. 4. **Monitoring**: Successful entries update live occupancy. Exits update the internal count. Security sees who is inside at any moment. 5. **Audit**: Every decision, including officer overrides and deny reasons, is written to tamper-resistant logs. 6. **Incident Response**: If an anomaly or emergency occurs, the same record chain feeds directly into incident and emergency workflows. Rekkeh works as an authorization layer on top of your existing infrastructure: boom gates, turnstiles, RFID readers, and cameras. The five product surfaces (Admin, Kiosk, Access Control Engine, Gate Ops, and Member App) each own one part of the chain, producing a single source of truth for physical security.
