Hirsch uTrust 4000 Clamshell Card - 36 BIT S10601

The Hirsch uTrust 4000 Clamshell Card is designed for organizations utilizing 125kHz proximity credential technology with 36-bit S10601 formatting. As part of the Hirsch (formerly Identiv) uTrust credential family, these cards deliver reliable performance for new and existing physical access control systems.

Built in a rugged clamshell format, these credentials are engineered for long-term durability in high-traffic environments. The reinforced housing ensures consistent performance in demanding daily use conditions, making them well suited for commercial facilities, healthcare campuses, educational institutions, government sites, and industrial environments where credentials are frequently handled.

Unlike printable ISO cards, the clamshell design is optimized for durability rather than visual personalization, offering a long-lasting solution for secure access control deployments.

Programmed using 36-bit S10601 formatting, these credentials support structured encoding for compatibility with established access control system architectures.
