Core Features of an AEPS Portal Before starting development, you need to understand the main modules required in a modern AEPS portal. 1. User Registration and Login Your AEPS portal should support: Retailer registration Distributor onboarding KYC verification Secure login and password reset 2. Retailer Dashboard The retailer panel should include: New transaction option Transaction history Wallet balance Commission report Settlement status 3. Distributor and Master Distributor Panel These panels help manage sub-users, commissions, and team-level activity. 4. Admin Panel The admin section should control: User approvals KYC checks Commission slabs Reports Transaction monitoring Fraud alerts Dispute handling 5. AEPS Transaction Module This is the main transaction engine that enables: Cash withdrawal Balance inquiry Mini statement Aadhaar authentication flow 6. Wallet and Settlement System A good AEPS portal should include: Retailer wallet management Auto commission calculation Settlement tracking Ledger reports 7. Biometric Device Integration AEPS depends on biometric authentication, so the portal must support devices such as: Mantra Morpho Startek Related read: How to Buy AEPS Biometric Devices Step-by-Step Guide to Build an AEPS Portal Step 1: Define the Business Model Before development begins, decide the structure of your AEPS portal. Important questions: Will it serve only retailers or also distributors? Will you offer white-label solutions? Will the portal include recharge, bill payment, or money transfer? Will users operate through wallet deduction or direct settlement? How will commissions be distributed? This planning stage is critical because it affects your portal architecture and future scalability.

This role-based structure helps keep the portal organized and secure. Step 3: Design the AEPS Portal UI/UX Your portal must be simple and easy to use because many AEPS agents are not highly technical. Focus on: Clean transaction forms Easy bank selection Clear fingerprint instructions Visible wallet balance Fast report access Mobile-friendly design A good AEPS portal UI improves transaction speed and reduces user error. Step 4: Choose the Technology Stack A reliable AEPS portal needs a strong and scalable technology stack. Frontend options: React Vue.js Angular Backend options: Laravel Node.js PHP Java Python Database options: MySQL PostgreSQL MongoDB Hosting options: AWS Google Cloud DigitalOcean Choose a stack that supports security, scalability, and real-time transaction handling. Step 5: Build the Frontend Portal The frontend should include: Login page Registration page Dashboard Transaction pages Reports section Profile settings Support section Important design goals: Fast loading Clear transaction status Easy navigation Low confusion during Aadhaar-based flow Step 6: Develop the Backend System The backend is the main engine of your AEPS portal. It should handle: User management Wallet logic Transaction processing API request/response handling Commission distribution Reports and logs Admin controls This is where your business logic lives. Step 7: Integrate the AEPS API No AEPS portal can function without AEPS API integration. The API handles: Transaction request submission Bank response handling Authentication status Failure and success callbacks A typical flow looks like this: Retailer logs in Customer enters Aadhaar details Bank is selected Fingerprint is captured Request is sent via AEPS API Response is received Portal updates wallet, status, and receipt Related read: AEPS API Integration Explained Step 8: Integrate Biometric Device Support Biometric support is one of the most important parts of the portal.
