Setting up a prepaid billing engine that talks to a MikroTik or RADIUS backend is usually more about the accounting logic than the login page itself. If the session limits and real-time deductions aren't perfectly synced, you end up with users getting free bandwidth or getting kicked off while they still have a balance. I have handled similar transaction management and user tracking for GreenCharge, where real-time balance accuracy was the priority. For your hotspot, I would set up a captive portal that triggers a webhook to your billing engine the moment a mobile payment clears. This ensures the user is authenticated and their session starts without you having to touch a thing. I will focus on getting the M-Pesa or mobile wallet integration right first, as that is the heart of the hands-off revenue model you're after. I can put together a quick billing dashboard sketch for free so you can see the technical approach first. ~ Rajesh

Hello there, I will deliver the authentication module, prepaid billing engine, mobile payment integration, and admin dashboard for your hotspot environment — all tied together through FreeRADIUS and your hotspot controller. One thing I will architect upfront: a token-bucket metering approach where each user session decrements balance via interim RADIUS accounting updates rather than relying solely on session-end packets. This prevents balance leakage from dropped sessions or ungraceful disconnects — a common issue in public Wi-Fi deployments. Questions: 1) Which hotspot controller are you using — MikroTik, CoovaChilli, or another platform? 2) Which mobile payment provider is the priority for launch — M-Pesa, or a specific regional wallet? Looking forward to discussing further. Best regards, Kamran

The most reliable way to build hotspot authentication with prepaid billing is to pair a RADIUS server with a PHP-based management API that handles voucher creation, session limits, and payment events separately from the access control layer, trying to do it all in one place is where most hotspot systems eventually break under load or concurrent logins. The hidden risk is session leakage when a user's payment expires mid-session or they reconnect on a different device, which needs explicit handling in both the RADIUS attributes and your billing reconciliation logic. I'd have the core RADIUS setup, captive portal flow, and PHP admin panel with voucher generation ready within the first week, then plug in the payment gateway in week two once the access logic is solid. Are you running this on MikroTik or a different router platform, because the RADIUS integration and hotspot redirect setup differ quite a bit depending on your hardware? Best, Salman Noreen

Hi there, I see you're building a managed Wi-Fi solution where user access is tied directly to a prepaid balance. The system will intercept connection requests, route users to a captive portal for authentication (or top-up via mobile payments), and then communicate with the hotspot controller via RADIUS to authorize and meter the session based on their available time/data credit. When the balance is depleted, the system will terminate the session automatically. Technical approach: - Backend: Node.js (Express) or Spring Boot API for core logic. - Database: PostgreSQL for user accounts, plans, and transaction logs. Redis for active session management. - Hotspot Integration: A dedicated service managing the RADIUS protocol (authentication, accounting, CoA/Disconnect packets) to interface with your controller (e.g., MikroTik). - Frontend: React.js for both the captive portal and the admin dashboard. - Deployment: Docker containers for each component to ensure easy replication. Core modules: - Authentication & Session Control: Handles user sign-in/sign-up and communicates with the RADIUS server to initiate/terminate sessions and enforce policies like idle timeouts. - Real-Time Accounting Engine: Processes RADIUS accounting packets to decrement user balances based on usage. Manages plan validity and expiration. - Payment & Top-Up: Integrates with mobile payment gateways (Stripe or regional providers) to handle credit purchases and automatically update user balances upon successful payment. Implementation strategy: We'll begin by setting up the core backend and RADIUS integration to establish a proof-of-concept with your hotspot controller. Next, we'll build the prepaid billing logic and payment gateway integration. The user-facing captive portal and admin dashboard will follow. The entire system will be containerized from the start for seamless deployment. Regards, Rohit

Hi I can build the server-side hotspot authentication and prepaid billing system with secure captive portal login, RADIUS-based access control, prepaid balance metering, and mobile wallet top-up support. I have experience with FreeRADIUS, MikroTik, CoovaChilli-style hotspot flows, REST APIs, payment gateway integration, session accounting, database design, Docker deployment, and admin dashboards. The main technical problem is keeping authentication, session limits, bandwidth/time usage, and prepaid deductions synchronized in real time, so I would design a RADIUS accounting engine with clear usage tracking and balance enforcement. The system can support username/password, email verification, or social login while still enforcing idle timeouts, session limits, and plan-based access rules. I can integrate mobile payment gateways such as M-Pesa, Apple Pay, Google Pay, or a local provider through the captive portal so users can buy or top up credit smoothly. The admin panel can manage plans, users, payments, usage logs, revenue reports, and hotspot nodes from one place. This approach will give you a repeatable, documented, and scalable hotspot billing backend that can be deployed across additional locations. Thanks, Hercules

Hi, Your hotspot billing project is a strong fit for a secure backend and network authentication workflow. I can help build a server side system that connects user authentication, prepaid accounting, captive portal payments, and admin reporting into one reliable platform. I have experience designing backend systems with RADIUS style authentication flows, session control, usage tracking, payment gateway integration, and admin dashboards. For this setup, I would recommend FreeRADIUS with MikroTik or CoovaChilli integration, a backend API for billing logic, and a database layer to track users, plans, balances, sessions, top ups, and revenue reports. The prepaid engine can deduct by time or bandwidth, enforce idle timeouts and session limits, and update balances in real time. The captive portal can support username login, email verification, or mobile number based onboarding, with mobile wallet top ups through M-Pesa, Apple Pay, Google Pay, or another gateway depending on your target market. I can also provide deployment scripts, documentation, and a scalable structure for adding more hotspot nodes later. Best, Justin

I’ve implemented prepaid Wi-Fi billing with RADIUS and CoovaChilli for public hotspots before, so I know how to securely tie user sessions to prepaid balances without disrupting the user experience. A realtime billing engine that deducts credit based on session time or data use is key, and I’ve connected payment gateways like M-Pesa and Google Pay directly into captive portals for seamless top-ups. To keep the system manageable, I suggest building a lightweight admin dashboard focused on plan management, logs, and basic revenue reports. Have you considered which hotspot controller hardware you’re using or if you prefer containerized deployment to simplify scaling? Also, do you want to support social login to speed onboarding, or keep it simpler with email/password? I can deliver a full solution with session enforcement, idle timeouts, and secure prepaid accounting, plus documentation and scripts to replicate your setup smoothly. Ready to start building this system for you now.

Hello, I would like to schedule a discussion about your Wi Fi hotspot authentication and prepaid billing system. The requirements are clear and align closely with work I have done on authentication driven platforms with real time session tracking and payment based access control. I have experience designing backend systems where user sessions are controlled through time or usage limits, and where balance deductions happen in real time based on active connectivity. I have also worked on payment flows that integrate mobile wallets and handle top ups with immediate reflection in user accounts, which fits well with your prepaid model. From what you described, the key success areas will be reliable session control, accurate usage tracking, and fast payment confirmation so users are never stuck during login or recharge. I can also structure the admin side so you can manage plans, monitor usage, and track revenue without complexity. I would be happy to walk you through a proposed architecture, discuss payment options suitable for your region, and confirm the best approach for integrating with hotspot systems such as RADIUS based environments or MikroTik style setups if needed. Please let me know a suitable time for a short meeting so we can align on technical direction, timeline, and deployment approach. I will share my portfolio in chat I look forward to hear from you. Thanks Best Regards, Mughira
