Pre-Encoded with our choice of bit format, facility code & number range.

• Highly secure – Like all Seos credentials, Seos Essential is Secure Identity Object® (SIO)-enabled, allowing for multi-layered security beyond the card technology and protecting identity data from unauthorized access
• Simplified, cost-effective migrations – Support for read/write identification using 125 kHz contactless technology to enable migration from legacy 125 kHz credential technologies
• Convenient – Fully supported by HID Signo, iCLASS SE®, multiCLASS® SE, HID Prox and Indala reader platforms
• Heightened privacy protection – Seos Essential offers best-in-class data and privacy protection by incorporating mutual authentication and secure messaging mechanisms into stringent best practices for data protection
• Programmed with a single SIO-based physical access control application for simplicity
• AES-128 cryptographic algorithms for data protection during communication with the reader to defend against attacks attempting to intercept data
• Prioritization of user privacy, always defaults to using a random contactless unique identifier (4 bytes random value)
• Ultra-fast read speeds with a high-performance hardware chip integrating co-processor for cryptographic calculations with symmetric keys
• Supports ISO/IEC standards: 7810, 7816 and contactless cards (14443 A)
• Supports 125kHz HID Prox and Indala formats
• Data within the SIO is secured with a wrapper that provides key diversification, authentication signatures, and AES-128 based encryption
• Mutual authentication protocol with generation of diversified session key to protect each card session with secure messaging
• High resistance to common attacks (man in the middle, replay attacks and others)
• Seos Essential is fully supported by HID Signo Readers
• Seos Essential is fully supported by iCLASS SE and multiCLASS SE Readers that can process SIO-enabled data formats.
• Only supported by iCLASS SE Readers with firmware Revision E or later.
• 125kHz capabilities are fully supported by HID Prox and Indala Readers
