As the financial industry embraces digitalization, EMQX powers a unified payment platform, providing secure and low-latency connectivity for millions of smart payment devices, from POS machines to QR code scanners.
The Challenge: Scaling a High-Performance Payment Platform
The rise of Integration Payment has transformed the financial landscape, consolidating various payment channels like Alipay, WeChat Pay, and credit cards under a single platform. However, building such a system presents significant technical hurdles:
- Massive Device Connectivity: The platform must support millions of payment terminals, including smart POS, QR code scanners, and voice-activated speakers, requiring a solution that can handle an unprecedented number of concurrent, encrypted connections.
- Low Latency Under High Load: Financial transactions demand real-time processing. The system must ensure low-latency communication even as millions of devices send and receive data simultaneously.
- Security & Data Integrity: With sensitive financial data involved, every connection must be encrypted and authenticated to prevent unauthorized access and ensure data security.
- Scalability for Future Growth: The system needs to be highly scalable to accommodate the rapid growth of the IoT ecosystem, from hundreds of thousands to tens of millions of devices.
The Solution: EMQX as the Core Connectivity Engine
To address these challenges, the platform chose EMQX as its core messaging and connectivity solution. EMQX’s capabilities were instrumental in building a robust and secure financial IoT system:
- Lightweight and Reliable Protocol Access: EMQX's full compatibility with the lightweight MQTT protocol ensures efficient, low-bandwidth communication, which is ideal for resource-constrained payment devices and complex network environments.
- Advanced Security with Multiple Authentication Methods: EMQX provides a secure foundation for all transactions. Devices connect using MQTT over TLS, ensuring end-to-end encrypted communication. Additionally, EMQX integrates with a backend database for authentication and ACL data, providing both device and application-level security.
- High-Performance Data Processing with the Rule Engine: The EMQX Rule Engine filters, transforms, and bridges high-volume transaction data to backend systems. By using Kafka as a high-performance data stream service, EMQX can process business data in milliseconds, enabling real-time display or voice broadcast of transaction results on payment devices.
- Seamless Integration and Scalability: EMQX’s support for multi-language hook functions (Python/Java) and rich API interfaces allows for rapid development and expansion of new business services with minimal effort. Its high-concurrency and distributed cluster architecture ensures high availability, with an SLA of 99.99% or higher, guaranteeing stable operation even under massive load.
