JCOP from day one. The platform that runs underneath transit, telco and e-gov.

Cardzgroup added JCOP — the Java Card Open Platform — to its product line in January 2009, the same month a million-unit South African PVC loyalty win was announced. Two months later, the line picked up NXP MIFARE DESFire EV1 in 2k / 4k / 8k variants, ISO/IEC 14443A and 7816-4 compliant.

That sequence — JCOP for multi-app contact, DESFire for high-end contactless — has been the spine of the smart card line ever since. We add new generations as they ship: DESFire EV2, then EV3; MIFARE Plus; the latest NTAG variants for high-volume NFC.

The fundamental capability has not changed: bilingual project management, in-house encoding bureau, full inspection on every card, ISO-accredited partner factories. What has changed is the chip catalogue underneath.
