Hirsch 4000 Clamshell Prox Card - 26 Bit 40134
The Hirsch 4000 Clamshell Prox Card is designed for organizations utilizing 125kHz proximity technology with 26-bit 40134 access control formatting. These credentials provide reliable, contactless entry for secure building access across commercial facilities, educational campuses, healthcare organizations, government properties, and industrial environments.
Featuring a rugged clamshell construction, the Hirsch 4000 is built for durability in demanding daily-use environments. The thicker card body helps resist bending, cracking, and general wear, making it a preferred choice for employee badges, tenant access, visitor management, and contractor credentials where long-term performance is required.
The clamshell design also supports practical use with badge clips, and lanyard attachments, ensuring the credential remains easily accessible for frequent scanning throughout the day.
Programmed using 26-bit 40134 formatting, these credentials require a facility code and unique card number range to ensure compatibility with existing access control systems. Organizations ordering programmed credentials will typically need to provide their current facility code and sequential numbering requirements.
