# TrustPay Lite
Digital Receipt and Micro Business Verification System for Informal SMEs in Adamawa State
## Project Overview
TrustPay Lite is a lightweight digital receipt and transaction verification platform designed to support informal small and medium enterprises in Adamawa State, Nigeria.
Thousands of market traders, POS agents, freelancers, and small shop owners operate without reliable digital transaction records. Paper receipts are easily lost, altered, or disputed. This prevents access to financial services and limits economic growth.
TrustPay Lite enables merchants to generate secure digital receipts with unique IDs and QR codes while building a basic transaction history that supports financial inclusion.
**Impact Pillar:** Financial Inclusion
## Problem Statement
In Yola markets and across Adamawa State:
- Transactions are mostly verbal or paper based
- Receipts can be lost or manipulated
- Merchants lack reliable income history
- Financial institutions cannot assess informal traders
- Small businesses struggle to access loans and grants
Trust and documentation gaps continue to exclude informal SMEs from the digital economy.
## Solution
TrustPay Lite provides:
- Merchant registration and login
- Secure transaction recording
- Automatic digital receipt generation
- Unique receipt ID for each transaction
- QR code attached to every receipt
- Public verification page to confirm authenticity
- Merchant dashboard with transaction history
The system increases transparency, reduces disputes, and builds verifiable digital records.
