HID® iCLASS SEOS® + Proximity Smart Cards

HID® iCLASS SEOS® + Proximity smart cards deliver a powerful, future-ready credential solution that combines advanced security with seamless backward compatibility. Designed for organizations transitioning from legacy systems, these dual-frequency cards support both 125 kHz proximity and 13.56 MHz SEOS® smart card technology, allowing you to upgrade security without replacing your entire reader infrastructure.

With this dual-technology capability, users can continue to access existing low-frequency systems while leveraging the enhanced encryption, privacy protection, and security features of SEOS®—making it an ideal solution for phased migrations and enterprise-wide upgrades.

The iCLASS SEOS platform enables true credential convergence, allowing a single card to securely manage both physical access (doors, gates) and logical access (network login, workstations, and cloud systems). With support for advanced authentication methods such as one-time passwords (OTP), organizations can strengthen identity verification while simplifying the user experience.

When integrated with HID’s identity management solutions, including Active Identity, SEOS credentials provide a single, unified credential for all access needs, reducing administrative complexity while improving overall security.

Key Features:

• Dual-frequency credential (125 kHz Prox + 13.56 MHz SEOS®)
• Seamless migration from legacy proximity to secure smart card technology
• Supports both physical and logical access control in one credential
• Advanced encryption and strong authentication capabilities
• Protection against cloning, replay attacks, and unauthorized access
• Privacy-focused design with no traceable card identifiers
