Hirsch 4020 ISO Composite Prox Card - 26 Bit H10301
The Hirsch 4020 ISO Composite Prox Card is designed for organizations utilizing standard 26-bit H10301 proximity credential formatting within their physical access control environment. Operating on 125kHz proximity technology, these credentials provide reliable facility access management for commercial buildings, schools, healthcare facilities, government organizations, and industrial security applications.
Manufactured using durable composite card construction, the Hirsch 4020 offers improved resistance to heat, bending, and everyday wear compared to standard PVC cards. This enhanced durability makes composite cards ideal for environments where credentials are frequently used, printed, laminated, or exposed to demanding daily conditions.
The standard ISO card format supports compatibility with badge holders, lanyards, and ID card printing systems for organizations requiring both electronic access control and visual identification capabilities. Programmed using the widely adopted 26-bit H10301 format, these credentials require a facility code ranging from 0 to 255 and a unique card number between 0 and 65,535.
Organizations ordering programmed credentials will typically need to provide their existing facility code and preferred numbering sequence to maintain compatibility with their current credential deployment.
