Overview:
The contactless fingerprint card is a passive fingerprint recognition device mainly composed of theprocessor chip ofCCM4202S , fingerprint sensor and NFC chip. It has the advantages of durability, corrosion resistance, strong anti-static, small size, low power consumption, high security, etc.
The card completes fingerprint data extracting, processing, template matching, and storage entirely within the CCM4202S, ensuring fast processing. It communicates with outside through radio frequency modulation interface ,and supports custom COS systems, serving as a secure carrier for digital certificates and private keys based on the public key infrastructure (PKI). Key pairs are generated or imported within the fingerprint card, and the private key cannot be exported that ensure the information security of the certificate holder. Additionally, it employs a dual authentication mechanism of "hardware + fingerprint" to ensure the legitimate use of digital certificates and private keys, providing a high-security level certification environment.
It is distinguished by anti-attacks, non-replicability, and inoperability when lost, making it superior in high-security access control systems, digital encrypted wallets and other fields.
