+# Phase 8: Visitor Management & Access Control
+
+## 1. Overview
+
+A comprehensive system to track visitors, contractors, and inspectors. Replaces paper logs with a digital kiosk, digital badges, and an admin "Panopticon" for real-time facility oversight.
+
+## 2. Core Features (Sprint 1)
+
+### 2.1 Digital Kiosk
+
+- **Self-Service Check-in:** Tablet-friendly UI for visitors to input details.
+- **Data Capture:** Name, Company, Purpose, Host (Employee), Photo (Webcam), NDA Signature.
+- **Badge Generation:** Instant creation of a visit record.
+
+### 2.2 Digital Badge (No Printer Required)
+
+- **Workflow:**
+    1. Visitor completes check-in.
+    2. Kiosk displays a unique QR code.
+    3. Visitor scans QR code with their own phone.
+    4. Phone opens `https://app.domain/badge/:visitId` (Public/Tokenized URL).
+- **Badge UI:**
+  - Visitor Photo & Name (Large)
+  - "Valid" Status (Pulsing Green Animation)
+  - Host Name
+  - Zone Access Level
+  - Expiry Time (Countdown)
+  - **Dynamic State:** If admin revokes access, the phone screen updates to "INVALID" (Red) via polling/socket.
+
+### 2.3 Host Notification
+
+- Employee receives an alert (In-app/Email) when their visitor checks in.
+
+## 3. "Panopticon" Admin View (Sprint 2)
+
+### 3.1 Real-Time Dashboard
+
+- **Active Visitors:** List of all currently checked-in guests.
+- **Visual Status:** Time on site, host, assigned zone.
+- **Actions:**
+  - **Force Checkout:** Clock them out remotely.
+  - **Revoke Badge:** Instantly turn their digital badge RED.
+
+### 3.2 Badge Confirmation Suite
+
+- **Verification Scan:** Security guards can scan the Visitor's phone screen to verify authenticity (prevents screenshots).
+- **Audit Log:** Track every check-in, check-out, and access revocation.
+
+## 4. Data Model
+
+```prisma
+model Visitor {
+  id          String   @id @default(uuid())
+  name        String
+  company     String?
+  email       String?
+  phone       String?
+  type        VisitorType @default(VISITOR)
+  ndaSigned   Boolean  @default(false)
+  visits      Visit[]
+  createdAt   DateTime @default(now())
+}
+
+model Visit {
+  id          String   @id @default(uuid())
+  visitorId   String
+  visitor     Visitor  @relation(fields: [visitorId], references: [id])
+  hostId      String?
+  host        User?    @relation(fields: [hostId], references: [id])
+  photoUrl    String?  // Check-in photo
+  purpose     String?
+  status      VisitStatus @default(ACTIVE) // ACTIVE, COMPLETED, REVOKED
+  checkIn     DateTime @default(now())
+  checkOut    DateTime?
+  token       String   @unique // For public badge URL
+  zones       String[] // Allowed zones
+}
+
+enum VisitStatus {
+  ACTIVE
+  COMPLETED
+  REVOKED
+}
+```
+
+## 5. API Routes
+
+- `POST /api/visitors/check-in`: Create visitor/visit, upload photo, return badge token.
+- `GET /api/public/badge/:token`: Public endpoint to view badge status.
+- `POST /api/visits/:id/check-out`: End the visit.
+- `POST /api/visits/:id/revoke`: Invalidate the badge immediately.
