J2R110, J3R110, J2R150, J3R150, J3R180, J3R200 are JCOP4 series JAVA card is another pinnacle after J2A, J3A, J3D, J3H röð, on the basis of ensuring high security and high performance, gögn geymslurými eykst, and the Flash chip is used to make the computing speed of the chip faster and more stable. Áður en J3H röð JAVA (innifalið), all of them used EEPROM chips, og eftir J3R röð (innifalið), they all used Flash chips.
J2R110, J3R110, J2R150, J3R150, J3R180, J3R200 chips are available in EMV and SecID versions. The EMV útgáfa er aðallega notað í fjárhagslega sviði; 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. Sem stendur, the J3R SecID series has obtained the CC EAL 6+ vottorð. The RAM (þ.e., trasient Minni) 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.
