01. The Challenge & Problem

What Needed to Be Solved

Enterprise event venues required a high-speed handheld scanning app for gate attendants to validate attendee tickets with immediate visual pass/fail confirmation, clear denial reason messages, and camera controls in low-light environments.

02. System Architecture

How I Engineered the Solution

Developed with React Native and Vision Camera buffer streaming. Features instant Ticket Accepted / Ticket Denied screen overlays displaying clear rejection reasons (Expired, Already Scanned, Invalid Tier), combined with camera flashlight toggles, auto-reset scanning timers, and gate configuration settings.

03. Core Capabilities & Features

Key Production Features Built

Sub-200ms camera barcode/QR code ticket scanning via Vision Camera
Instant Ticket Accepted screen overlay with attendee check-in confirmation
Instant Ticket Denied screen overlay showing exact rejection reasons (Already Scanned, Expired, Invalid Tier)
Configurable scanner settings (auto-reset timer for next scan, camera torch flashlight toggle)
Offline check-in buffer logging for unreliable venue Wi-Fi networks
04. Production Result & Business Impact

Processed 10,000+ attendee ticket scans per event with zero admittance bottlenecks.
