Ј2Р110, Ј3Р110, Ј2Р150, Ј3Р150, Ј3Р180, J3R200 are JCOP4 series JAVA card is another pinnacle after J2A, Ј3А, Ј3Д, Ј3Х серија, on the basis of ensuring high security and high performance, повећава се капацитет складиштења података, and the Flash chip is used to make the computing speed of the chip faster and more stable. Пре Ј3Х серије ЈАВА (инклузивно), all of them used EEPROM chips, и после Ј3Р серије (инклузивно), they all used Flash chips.
Ј2Р110, Ј3Р110, Ј2Р150, Ј3Р150, Ј3Р180, J3R200 chips are available in EMV and SecID versions. ЕМВ верзија се углавном користи у финансијском пољу; 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. Сада, the J3R SecID series has obtained the CC EAL 6+ сертификат. The RAM (i.e., Меморијска рута) 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.
