Hirsch 4000 Clamshell Prox Card - 32 Bit Quadrakey

The Hirsch 4000 Clamshell Proximity Card is designed for organizations utilizing 125kHz proximity credential technology with standard 32-bit Quadrakey formatting. Commonly used in commercial facilities, healthcare environments, educational institutions, government buildings, and industrial security programs, these credentials provide dependable performance for everyday access control needs.

Featuring a rugged clamshell construction, these proximity cards are built for high-use environments where durability is essential. The thicker card body helps resist bending, cracking, and general wear from daily handling, making them ideal for employee access credentials, contractor badges, and long-term issued cards.

These credentials are compatible with standard 125kHz proximity reader systems and provide consistent read performance when properly programmed with the correct credential numbering sequence.

Organizations ordering programmed Quadrakey credentials will typically need to provide card numbering requirements to ensure compatibility with their existing access control enrollment and credential management system.
