SED PAY simplifies how individuals and businesses send, receive and manage money, including in regions with limited connectivity. Instant transfers, bank and mobile-money support, strong security and smart transaction insights in one lightweight app.

The Challenge

Millions of users in developing regions rely on slow, unreliable or expensive financial tools.
The wallet had to work equally well for daily personal needs and small-business cash flow.
It needed to stay usable on limited data while meeting financial regulations.

What We Built

Instant peer-to-peer transfers, deposits, withdrawals and recurring payments.
Multi-currency wallets with bank and mobile-money integrations.
Biometric login, encrypted local storage, real-time fraud monitoring and KYC onboarding that does not slow users down.
Business tools for managing payments, customers and multiple accounts.
An offline, proximity-based transfer architecture for wallet-to-wallet payments without internet.

How We Did It

Build. Flutter client tuned for low data consumption and stable behaviour across bandwidths.
Backend. Node.js and MongoDB powering transfers, integrations, transaction history, fraud pipelines, support ticketing and analytics.
Security. Advanced encryption standards and continuous monitoring on every transaction.

Outcome

One trusted app for paying family, running a business and handling daily purchases.
Transparent transaction details and alerts for every account activity.
A bridge between traditional banking and everyday digital payments for underserved communities.
