The NXP P71 JCOP4 J3R200 is a high-performance dual-interface Java smart card chip developed by NXP based on its JCOP 4.0 security operating system. It utilizes the SmartMX™ security controller architecture and is compliant with JavaCard 3.0.5. GlobalPlatform 2.3, and is specifically designed for high-security applications such as financial payments, e-government, digital RMB hardware wallets, and integrated transit cards. The chip is Common Criteria EAL6+ certified and supports both global mainstream cryptographic standards and Chinese national cryptographic algorithms. As a benchmark product in the international high-end smart card market, it is widely deployed in core financial and government systems across China, Europe, and the Asia-Pacific region.
High-security architecture: Integrates a hardware security module (HSM) and supports protection against side-channel attacks (SPA/DPA), fault injection, and physical tampering, meeting financial-grade and government-grade security requirements.
Dual-interface communication: Supports both contact (ISO/IEC 7816) and contactless (ISO/IEC 14443 Type A/B) interfaces simultaneously, with contactless communication speeds up to 848 kbit/s and up to 3.2 Mbit/s in VHBR mode.
Java Card 3.0.5 Compatibility: Runs on the JCVM, supporting dynamic loading of multiple applets, isolated execution, and remote management (GlobalPlatform 2.3).
Full Algorithm Support:
1. Symmetric Encryption: AES-128/192/256, 3DES, SM4 (National Cryptographic Standard)
2. Asymmetric encryption: RSA (1024–4096 bits), ECC (NIST P-256, Brainpool, SM2)
3. Hash algorithms: SHA-256, SM3
4. True Random Number Generator (TRNG): Complies with AIS-31 Class B/C standards to ensure secure key generation.
Remote Lifecycle Management: Supports over-the-air card issuance, application downloads, and key updates via secure channels (SCP02/SCP03), suitable for long-term financial and government card systems.
Low-Power Design: Supports wide-voltage operation from 1.62V to 5.5V and features a sleep mode, making it suitable for battery-powered terminal devices.
Financial Payments: As the core component of EMV-compliant chip cards, it is widely used in debit and credit cards issued by major state-owned banks such as the Industrial and Commercial Bank of China and the China Construction Bank, supporting “QuickPass” and PIN-authenticated transactions.
Digital RMB Hardware Wallet: Selected as the core security element for the visual hardware wallet to be launched by Bank of China in Shenzhen in 2024, it supports offline payments, dual-offline transfers, balance display, and dynamic QR codes, covering high-frequency scenarios such as airports and border crossings.
Urban Public Transportation: Integrated into the “One Card” systems of cities such as Guangzhou, Nanjing, and Wuhan, it enables rapid access across multiple scenarios—including subways, buses, and ferries—while supporting small-value payments.
E-Government Identity Credentials: Used in certificate issuance systems for provincial e-ID cards, social security cards, and residence permits, supporting encrypted biometric storage and online identity verification. Deployed in pilot provinces such as Guangdong and Jiangsu. Enterprise Security and IoT: Applied to enterprise access control cards, T-Box communication modules, and industrial control terminals to enable device identity authentication, secure firmware boot, and encrypted communication links.
Cases
Bank of China Digital RMB Visual Hardware Wallet (Shenzhen): In November 2024, Bank of China unveiled its first digital RMB hardware wallet supporting “visual display, tap-to-pay, and QR code scanning” functions at the Shenzhen International Financial Expo. The device utilises the NXP P71 J3R200 as its underlying security chip, enabling a 1-millimetre-thick e-ink display and supporting both passive and active dual-mode operation. Thirty-four self-service card issuance machines have been deployed at Shenzhen Airport and border crossings to serve the elderly and foreign visitors to China.
Domestic Substitution of Financial IC Cards: In the EMV card upgrade projects of major state-owned banks, the NXP P71 J3R200—a chip offering high security and compatibility—is being used to replace outdated financial IC cards. It supports an annual issuance volume of over 100 million cards and meets the dual certification requirements of EMVCo and FIPS 140-2.
Government Terminal Integration: In the 2025 electronic ID card system upgrade by the Guangdong Provincial Special Document Production Centre, the requirement was explicitly stated to use “CPU card chips supporting national cryptographic algorithms.” The NXP P71 J3R200, having passed National Cryptographic Level 2 certification and achieved EAL6+ security rating, became one of the core candidate solutions and was integrated into public security mobile law enforcement terminals and government self-service kiosks.
