Supplier's note

  1. Technical Breakthroughs:

    • Modular Design: Gold-edge durability ensures longevity in harsh environments, reducing replacement costs.
    • Cross-OS Support: With compatibility from Android 6.0.1 to Linux, it bridges legacy and modern systems.
    • Anti-Spoofing Certification: ISO/IEC 30107 compliance safeguards against fingerprint replication attacks.

  2. Model Selection Guide:

    • Base Model: Ideal for small-scale deployments (e.g., office access) where budget constraints are key.
    • Advanced Model: Best for mid-tier applications (e.g., hotels, retail) needing AI-enhanced enrollment and broad OS support.
    • Pro Model: Tailored for critical infrastructure (e.g., data centers, military) requiring tamper-proof security and ultra-fast authentication.

With the Pro Model’s 1-second enrollment speed, you can reduce user wait times by 50% compared to industry benchmarks. Paired with its tamper-proof housing, this creates a near-impenetrable biometric barrier for high-security scenarios.
