We developed an NFC card encoder device for DUSAW, a leading smart lock provider. The goal was to create a device that could securely communicate with DUSAW’s system and read/write lock cards without requiring installation or modifications to existing property management systems.
We were responsible for:
- Selecting and integrating components with NFC read/write capabilities
- Developing firmware for seamless communication with a remote server
- Establishing API communication for real-time data exchange
- Implementing secure read/write functionality for lock cards
- Conducting rigorous unit and integration testing to ensure reliability
- Delivering full documentation for ease of use by clients
Process & Challenges
- Ensuring encrypted communication between the device and DUSAW server to protect access credentials
- Designing a secure read/write process to prevent card corruption or failed operations
- Integrating with physical Lock APIs to fetch sector data and encode keycards dynamically
- Optimizing performance on a hardware-limited device while maintaining real-time responsiveness
Outcome & Impact
- Fully integrated NFC solution for DUSAW clients without requiring system modifications
- Seamless interaction with REST APIs, eliminating dependency on DLLs or proprietary software
- Improved reliability and security of lock card issuance across properties
- Clients can easily deploy the encoder device in hotels and other facilities, simplifying property management
