The safe chip technology in our JAVA card works at 13.56MHz and supports ISO/IEC 7816 and product standards for easy applet creation. This product offers over 100,000 write/erase cycles and data retention for 10 years or more. It has DES/3DES/AES encryption, financial-grade security certification (Common Criteria EAL4+), and storage choices range from 1KB to 72KB EEPROM. We offer fast delivery (7–15 days for standard goods) and flexible customisation starting at 500 units. Our IoT hardware knowledge spans more than 15 years, and we can produce more than 500 million units each year.
Not just a card will do. You need an all-in-one answer that works right away.
Proven Security Architecture
Your info should be kept safe at all times. Our cards have security chips from NXP SmartMX, Infineon SLE, and Huada Electronics that are known all over the world. Attacks and unauthorised entry are blocked by multiple layers of encryption. You can trust this technology just like banks do.
Real Programmability
Through product software creation, you can change how your card works. You can add features, change security methods, or connect to systems that are already in place without having to buy new hardware. As your needs change, this gives you the freedom to save time and money.
Built to Last
When you use high-quality PVC and PET materials every day, they will last. These cards work consistently in temperatures ranging from -25°C to +70°C, so they can handle harsh conditions and keep up their performance even in big deployments.
