CR80 ISO/IEC14443A/B, 13.56MHz Contactless CPU Yangcheng Tong Commemorative Card

Description

A contactless CPU card is a smart card that integrates a microprocessor (CPU) with radio frequency communication, functioning like a “microcomputer” without a battery. It relies on the radio frequency field of the reader for power supply and communication. It features high security, multiple applications, and fast transactions, and is suitable for use in transportation, finance, access control, and other scenarios.

1. Core hardware and communication
• Structure: Integrated CPU, ROM, RAM, EEPROM, COS (on-chip operating system) and antenna, passive design (powered by the reader).
• Communication: Adheres to ISO/IEC 14443 (13.56MHz), supports contactless reading and writing, and boasts fast transaction speed (completed within approximately 100ms).
• Conflict prevention: Supports multiple cards being present simultaneously, enabling precise selection of the target card and avoiding interference.

II. Core functions
1. Financial-grade secure computing: Equipped with built-in algorithms such as DES/3DES/AES/RSA, it can perform encryption, decryption, and signing within the card; supports mutual authentication, dynamic keys, random number anti-replay, with keys not exposed, tamper-resistant, and anti-copy.
2. Multi-application isolation on one card: COS provides an “application firewall”, where different applications (transportation, payment, access control) are isolated in separate zones and with separate keys, so they do not affect each other, enabling multi-purpose use of one card.
3. Offline transactions and dynamic updates: Support offline consumption (such as bus card swiping), with automatic synchronization upon network recovery; remote updates of keys, applications, and parameters are supported, accommodating business upgrades.
4. Identity recognition and data storage: It allows for registered loss reporting, stores user information, transaction records, permission data, etc., with a capacity of 1K-64K bytes, and can retain data for over 10 years.
5. Cross-terminal/cross-regional compatibility: Compliant with standards such as PBOC and Joint Transportation, supporting nationwide interconnectivity and multi-terminal adaptation.

III. Typical Applications
• Transportation: City One-Card (such as Shenzhen Pass), ETC User Card, CPC Pass Card, quick payment and path billing.
• Financial payment: QuickPass, electronic wallet, supporting quick transactions for small amounts.
• Identity management: access control, attendance tracking, campus/corporate smart cards, and operational qualification cards.
• Smart parking: automatic barrier lifting, time-based charging, and support for monthly/temporary card settlement.

IV. Key differences from logical encryption cards (such as M1)
Comparison items: Contactless CPU card, Logical encryption card
Security level: Financial grade, with built-in CPU and encryption computation, anti-duplication and anti-attack. The security mechanism is simple and easily cracked and duplicated
Multi-application support, application isolation, dynamic loading of single applications, no isolation mechanism
Transaction speed: Millisecond-level, compatible with fast lanes. Fast, but with simple security verification
The cost is relatively high

V. Key Technical Standards
• Communication: ISO/IEC 14443 A/B, 13.56MHz contactless communication.
• Security: PBOC 3.0, EMV, supports symmetric/asymmetric encryption.
• Industry: Joint efforts by the Ministry of Transport and the Ministry of Housing and Urban-Rural Development to establish interconnection standards for cross-city applications.
