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.
Microprocessor Cards
Full CPU-based smart cards with on-card processing capabilities, cryptographic coprocessors, and multi-application support for high-security deployments.
Hybrid Cards
Cards combining a contact chip and a separate contactless chip in a single card body. Each interface operates independently, enabling dual-system compatibility.
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.
Java Cards
Smart cards running the Java Card platform, enabling multiple applets from different providers on a single card. GlobalPlatform compliant for secure applet management.
