Hirsch 4000 Clamshell Prox Card - 33 Bit D10202

The Hirsch 4000 Clamshell Proximity Card is designed for organizations utilizing 125kHz proximity credential technology with standard 33-bit D10202 formatting. Featuring a rugged clamshell construction, these credentials are commonly used in commercial facilities, healthcare environments, educational institutions, government buildings, and industrial sites where long-term durability and consistent access performance are required.

The thick clamshell design is built to withstand frequent handling and harsh daily use, making it ideal for employee access credentials, contractor cards, and visitor management programs. These credentials provide reliable read performance in compatible 125kHz proximity reader systems while maintaining strong physical durability over time.

Unlike printable ISO cards, the clamshell format is optimized for strength and longevity rather than visual customization, making it well suited for high-volume access control deployments where durability is the primary requirement.

Organizations ordering programmed D10202 credentials will typically need to provide their assigned facility code and credential numbering sequence to ensure compatibility with their existing access control system configuration and enrollment structure.
