Scan, Pay, Power: APU’s Smart Meter Experience

| A smart, cashless solution for APU students to control room meter top-ups with just a scan and a tap.

🏢 Client Background

Asia Pacific University (APU) is a leading institution in Malaysia, focused on enhancing student experiences through smart technology. They needed an automated dorm energy management system that allowed students to top-up electricity independently, quickly, and securely.

🎯 Why the System Was Built

• Manual electricity top-ups were inconvenient for students and staff.

• Students needed a self-service, cashless top-up method.

• APU required a secure, integrated solution within their own mobile ecosystem.

• Needed real-time synchronization with smart meters to avoid delays and disputes.

🚀 Our Solution: QR-Based Smart Meter Top-Up System

• QR Code Smart Meter Access:
  Each room has a unique QR code; students scan to access and top up their meter quota.

• Seamless Web App Integration:
  We developed a web app fully embedded in APU’s mobile app, ensuring smooth user flow.

• Single Sign-On (SSO) Integration:
  APU handles user login and securely passes data to our system; we generate a signed URL for direct, verified access.

• Flexible Top-Up Options:
  Students choose from preset amounts (RM10, RM20, RM50, RM100) to suit their energy needs.

• Dual Payment Methods:
  Supports both Payment Gateway (credit/debit cards, FPX) and APcard (APU’s internal e-wallet).

• Real-Time Payment & Meter Update:
  Once payment is verified, smart meters are updated instantly — no delays.

🔧 Technology Stack

• Backend: Laravel
• Frontend: React Native (iOS & Android), Electron (Windows)
