Contact Interface

Contact Smart Cards

From basic memory cards to advanced Java Card platforms, our contact smart cards power secure applications in banking, government, healthcare, and enterprise security.

Contact Smart Card Technology

Contact smart cards communicate through a physical connection between the card's gold-plated contact pad and the reader's contacts, following the ISO/IEC 7816 standard. This direct electrical interface provides reliable, high-speed data transfer ideal for security-sensitive applications.

Cardzgroup manufactures contact smart cards ranging from simple memory ICs to powerful microprocessor-based platforms supporting Java Card, GlobalPlatform, and custom operating systems.

Card Types

Five product families covering every contact smart card requirement.

Memory Cards

Simple, cost-effective smart cards with EEPROM memory and basic security logic. Ideal for prepaid applications, loyalty counters, and stored-value systems.

Dual Interface Cards

A single chip connected to both a contact pad and an embedded antenna. The same data and applications are accessible via either interface -- contact or contactless.
