J2R110, J3R110, J2R150, J3R150, J3R180, J3R200 are JCOP4 series JAVA card is another pinnacle after J2A, J3A, J3D, sèrie J3H, on the basis of ensuring high security and high performance, la capacitat d'emmagatzematge de dades s'incrementa, and the Flash chip is used to make the computing speed of the chip faster and more stable. Abans de la sèrie JAVA J3H (inclusiu), all of them used EEPROM chips, i després de la sèrie J3R (inclusiu), they all used Flash chips.
J2R110, J3R110, J2R150, J3R150, J3R180, J3R200 chips are available in EMV and SecID versions. La versió EMV s'utilitza principalment en l'àmbit financer; The SecID version is mainly used in the field of electronic identity, and the ECC algorithm and Gen Key encryption algorithm are used in the field of electronic ID card. Al present, the J3R SecID series has obtained the CC EAL 6+ certificat. The RAM (és a dir,, memòria trasient) of the J3R series JAVA cards is 4K, which is 0.8K more than that of the J3H series, and the APDU Buffer Size can be expanded even more.
