NXP JCOP (Java Card Open Platform) is a family of Java Card-based secure smart card operating systems built on NXP's SmartMX/SmartMX3 hardware. They are widely used for payment, eGovernment, transit, and secure ID applications. JCOP supports Java Card API, GlobalPlatform, and various contact/contactless standards.
Key JCOP Generations in 2025:
- JCOP 2/3 series (older, legacy – still common for custom applications)
- JCOP 4 series (current mainstream – Java Card 3.0.5 + GlobalPlatform 2.3)
- JCOP 5 (latest EMV-focused – high-speed contactless)
