Secure License Management

Project Summary

When the client approached us with the challenge of modernizing their physical license management, we delivered the Secure License Management—an RFID-enabled device that streamlined secure storage and retrieval. The client aimed to eliminate manual processes and gain real-time tracking capabilities. Leveraging the ESP32 ARM-based controller, we created a robust IoT solution that integrated RFID card authentication, keypad input, and seamless data synchronization with the client’s remote server. This past project showcases our ability to deliver a tailored, scalable system that met the client’s unique needs.

Solution We Delivered to the Client

We collaborated closely with the client to bring the Secure License Management to fruition through end-to-end consulting, development, and integration. Here’s what we built for the client:

System Architecture

We designed a modular, scalable architecture, seamlessly integrating the ESP32 controller, RFID reader, and keypad to support the client’s operations.
Driver Development

We developed optimized drivers for UART, I2C, and UDP protocols, ensuring reliable communication across the client’s hardware and server.
Core Application

We crafted the main application to manage the client’s users’ interactions, enabling secure RFID authentication, keypad input, and accurate logging of license fetch and return events.
Server Communication

We implemented a UDP-based system to synchronize the client’s transaction logs in real time, keeping their data secure and accessible.

Technology Stack

Hardware: ESP32 ARM-based controller, RFID reader, Keypad
Software Tools: ESP-IDF IDE, Embedded C
Communication Protocols: UART, I2C, UDP

Outcome and Business Impact for the Client

Increased Efficiency: The client reduced manual license management efforts by 80%, allowing their team to focus on higher-value tasks.
Unmatched Reliability: The client’s system achieved 99.9% uptime for real-time data synchronization, ensuring consistent access to logs.
Enhanced User Experience: The client’s users completed transactions in under 5 seconds, thanks to intuitive RFID and keypad interactions.
Cost Savings: The client benefited from automated logging and remote management, minimizing errors and operational costs.
Future-Ready Solution: The client’s system was designed for scalability, supporting their long-term growth and integration needs.

Features the Client Benefited From

Secure Authentication

The client’s users accessed the system using RFID cards and keypad input, ensuring robust security.
Real-Time Logging

Every license fetch and return was logged with timestamps and instantly sent to the client’s remote server.
Reliable Communication

UART, I2C, and UDP protocols ensured flawless interaction between the client’s hardware and server.
User-Friendly Interface

The client’s team enjoyed an intuitive system, reducing training time and speeding up operations.
Scalable Design

The client’s solution was built to grow, ready to integrate with additional IoT devices as their needs evolved.

How We Engaged with the Client

We partnered with the client through a consulting, development, and integration model, enhanced by team augmentation:

Consulting: We worked with the client to define their requirements, design the system architecture, and select the optimal tech stack.
Development: Our embedded systems and software engineers built custom drivers, the client’s core application, and server communication protocols.
Integration: We seamlessly integrated all components, conducting thorough testing to ensure the client’s system’s reliability.
Team Augmentation: We embedded our experts within the client’s team, accelerating development, providing ongoing support, and ensuring the client had the knowledge to maintain the system.

This collaborative approach ensured we delivered a solution perfectly aligned with the client’s vision, with the flexibility to scale as needed.

Conclusion

The Secure License Management project transformed how the client managed licenses, delivering a secure, efficient, and scalable IoT solution. Our team augmentation model enabled us to work as an extension of the client’s team, ensuring their success. Building on this past achievement, we’re ready to partner with the client again to create their next innovative solution!
