XpandIT Controller Board: Ensuring Seamless Peripheral Communication

The XpandIT controller board is the core of Comark’s TabletArmor, serving as the central hub that powers and routes all connected peripherals to the tablet. It ensures seamless communication between devices such as fingerprint readers, barcode scanners, and proximity readers, enabling you to build sophisticated, fully integrated time-tracking systems on standard tablet platforms like Android and iOS.
With the XpandIT controller board, peripherals are managed through a single interface. This eliminates the complexity of juggling multiple connection points, allowing you to focus on software development while the hardware side runs smoothly.
Benefits of Using the XpandIT Controller Board for Time and Attendance Systems
- Seamless Peripheral Integration: Whether you’re connecting fingerprint readers for secure check-ins, barcode scanners for employee tracking, or proximity readers for contactless authentication, the XpandIT controller board ensures that each device communicates seamlessly with the tablet.
- Standard Tablet Compatibility: The solution supports Android and iOS platforms, enabling your software to run on widely available tablets while ensuring full communication with peripheral devices.
- Centralized Power and Control: All peripherals are powered and managed through a single source, simplifying setup and improving reliability.
- Scalable and Future-Proof Design: As your business grows or new peripheral technologies emerge, the XpandIT system’s modular architecture allows for easy expansion without replacing the entire hardware setup.

Comark’s SDK: Bridging Your Software and Kiosk Peripherals

The Comark SDK is purpose-built to connect your time and attendance software directly to the peripherals managed by the XpandIT controller board. Designed with cross-platform support for Windows, Android, and iOS, the SDK simplifies development and provides a cohesive set of tools for building robust, feature-rich applications.
Key Features of the Comark SDK:
- Cross-Platform Compatibility: Develop applications for multiple platforms using a single SDK, ensuring your software can run seamlessly on various devices. This flexibility reduces development time and simplifies deployment.
- Peripheral Integration Made Easy: The SDK manages all connected peripherals, enabling functionalities like biometric authentication, barcode scanning, and contactless check-ins without needing separate code for each device. This integration reduces errors and ensures reliable performance.
- Unified Control Over Peripherals: Control each connected device through a single point of access, eliminating the need to interact with individual peripherals separately. This streamlines software development and testing, making complex interactions between the tablet and peripherals easier to implement.
How the XpandIT Controller Board and SDK Work Together
The XpandIT controller board and Comark SDK provide a complete solution that bridges hardware and software integration, enabling developers to create time and attendance systems that run on standard tablet platforms with ease. While the XpandIT board handles peripheral communication and power, the SDK allows you to manage these peripherals directly from your application, streamlining development and ensuring reliable performance.
Example Use Case: Multi-Factor Authentication with a Fingerprint Reader

Consider a scenario where your time and attendance application requires multi-factor authentication using a fingerprint reader. The XpandIT controller board and Comark SDK streamline this process, allowing the fingerprint reader to work seamlessly with your software on platforms like Android and iOS.
With the SDK, you can manage peripheral functionality in real-time, enabling sophisticated authentication processes and integration with other devices like barcode scanners or proximity readers – all while keeping your development streamlined.
