Campus Security & Visitor Gate Passes

Digital visitor logging, mobile OTP verification, vehicle registration, and turnstile badge printing.

What It Is

Visitor Gate Pass replaces insecure paper gate registers with an encrypted digital checkpoint. Guards at the front gate capture visitor photos, verify contact numbers with instant OTPs, and track departure times.

Why It Exists & Institutional Purpose

Operational Challenge: Paper visitor registers have illegible handwriting, fake phone numbers, and zero tracking of when guests leave campus, creating serious child safety risks.

Key Operational Outcomes
  • Ensures zero unverified strangers enter the campus perimeter.
  • Sends an instant notification to the staff member or principal being visited.
  • Maintains an active headcount of all external visitors currently inside campus grounds.
  • Prints a time-stamped barcode badge that must be scanned at the gate upon exit.

How to Use: Web Admin Portal

Step-by-step procedure for campus administrators, principals, and accountants on desktop viewports.

1
Open Security Terminal
Navigate to 'Security Service > Gate Pass' on the front gate checkpoint computer.
2
Enter Visitor Details
Type visitor name, purpose of visit, person to meet, and visitor mobile number.
3
Verify Phone & Print Pass
Send instant SMS OTP or click 'Issue Pass'. The thermal printer dispenses the visitor slip.

How to Use: Mobile App Workflow

Touch gestures, haptic roll-calls, and QR code workflows on mobile phones and tablets.

1
Tablet Check-in
Guard uses the gate tablet to capture the visitor's photo and ID proof.
2
Log Checkout
When the visitor exits, guard scans the barcode on the badge to record exact exit time.
