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
