Fuel Card 13.56MHz Cpu

Description

The fuel dispenser CPU card is a smart contact/contactless IC card based on financial IC card specifications. Its core is equipped with an independent microprocessor chip, possessing independent computing and key management capabilities.
Core Hardware Components:
1. Microprocessor (CPU)
2. Storage Units:
◦ ROM
◦ RAM
◦ EEPROM
3. Communication Interface: Supports both ISO/IEC 7816 and ISO/IEC 14443 modes.
4. Encryption Module: Built-in symmetric encryption algorithms such as DES, 3DES, and AES; supports RSA asymmetric encryption; supports two-way authentication.

Core Software System:
1. Card Operating System (COS): The core software of the CPU card, responsible for managing card resources, executing security protocols, and processing transaction instructions. It supports multiple application partitions, with different applications running independently without interference.
2. Key Management Mechanism: Employs a multi-level key system (master key, application key, transaction key). Keys are stored in a hardware encrypted area and cannot be directly read. A random session key is generated for each transaction to prevent key cracking.
3. Secure Transaction Process: Transactions require four steps: “card authentication device → device authentication card → encrypted data transmission → transaction record retention.” The entire process is tamper-proof and copy-proof, and supports a gray lock function (locking the card in case of abnormal transactions).

Technical Advantages:
• High Security
• Scalability
• Strong Compatibility
