Project description:
"1. Project Overview

The EMI Mobile Locker & Device Protection System is a cross-platform (Android + iOS) security application designed for Retail Mobile Shop Owners who provide smartphones on EMI. The system gives sellers the ability to remotely lock, track, restrict, and monitor buyer devices until EMI payments are completed.

The solution functions similar to an MDM/DPC (Device Policy Controller) system with remote control features, tamper protection, and real-time monitoring, ensuring devices cannot be misused or reset until payments are cleared.

The complete system includes:

Android & iOS Buyer App

Central Admin Web Dashboard

Backend API, Authentication & Cloud Services

The app uses Phone Number + OTP login, ensuring secure and smooth onboarding for buyers.

Protect retail sellers from EMI fraud or non-payment.
