Hirsch 4000 Clamshell Prox Card - 26 Bit H10301

The Hirsch 125kHz Clamshell Proximity Card is designed for organizations using standard 26-bit H10301 credential formatting within their physical access control environment. Commonly deployed across commercial buildings, schools, healthcare facilities, government organizations, and industrial environments, these credentials provide a dependable solution for secure employee and visitor access management.

Operating on standard 125kHz proximity technology, these clamshell cards are commonly used in legacy proximity reader environments and are programmed using the widely adopted 26-bit H10301 format. Organizations ordering programmed credentials must provide their assigned facility code along with the appropriate card numbering sequence to maintain compatibility with their existing credential deployment.

Facility code and current serial number information can typically be located on previous credential packaging or enrollment documentation associated with your existing card inventory.
