Supplier's note

  1. Three Technical Breakthroughs:

    • ISO 14443A/B protocols: Enable compatibility with global access control systems.
    • 13.56MHz frequency: Ensures seamless interoperability with NFC-enabled cards worldwide.
    • Portable design: Reduces deployment costs in field operations by 30% compared to fixed readers.

  2. Optimal Version Selection:

    • Base Model: Ideal for small businesses needing basic access control (e.g., offices with 50+ users).
    • Advanced Model: Suitable for mid-sized enterprises requiring enhanced security (e.g., hospitals or retail stores).
    • Pro Model: Designed for high-security environments (e.g., banks or government facilities) where FIPS compliance and ultra-fast processing are critical.

With the Pro version’s military-grade encryption, you can securely handle sensitive data transfers in high-risk scenarios. Pair its 350kbps speed with the rugged metal casing to ensure reliability in harsh industrial settings. The Advanced Model’s AES-256 encryption, meanwhile, balances cost and security for everyday commercial use.
