Industrial Memory Card C10 U3 A1 A2 Class SD Card
This industrial-grade SD card with high-end chips and IC components is specifically designed for Automatic Fare Collection (AFC) systems in urban rail transit applications including subways and high-speed railways.
Core Technical Advantages for AFC System Requirements
High Concurrent Read/Write Performance
Capable of handling 3,000+ transaction requests per second during peak hours with random read/write IOPS ≥ 2000, ensuring zero transaction delay and complete data integrity.
Broad Temperature and Environmental Adaptability
Operating temperature range of -25°C to 85°C, designed to withstand harsh conditions including high humidity in underground stations, extreme heat exposure at ground stations, and severe cold in northern winters.
Key Values in AFC Systems
- Ensuring Transaction Continuity: Offline data caching during network interruptions with automatic synchronization upon restoration, enabling "offline non-downtime" operation
- Enhancing System Stability: Reduces equipment downtime from storage failures, lowers maintenance costs, and guarantees rail transit operational efficiency
- Data Traceability and Auditability: Complete recording of transaction details including time, location, amount, and device number for tamper-proof evidence chain
- Supporting Edge Computing Applications: Stores edge computing programs for transaction data preprocessing, passenger flow analysis, and abnormal behavior identification
- Reducing Total Cost of Ownership (TCO): 5-10 year service life outperforms consumer-grade cards, minimizing replacement frequency and operational labor
