IdentiSys IPC-9000 Clamshell Prox Card - 36 Bit N901157A
The IdentiSys IPC-9000 Clamshell Proximity Card is designed for organizations utilizing 125kHz proximity credential technology with 36-bit N901157A formatting. Featuring a rugged clamshell construction, these credentials are built for long-term durability and consistent performance in demanding access control environments. The 36-bit N901157A format is commonly used in Napco-compatible proximity systems.
The reinforced design makes these cards well suited for high-traffic facilities such as commercial buildings, healthcare campuses, educational institutions, government facilities, and industrial sites where credentials are used frequently throughout the day. The durable housing helps ensure reliable operation in compatible 125kHz proximity reader systems over extended daily use.
Unlike printable ISO cards, the clamshell format is optimized for durability and longevity rather than visual customization, making it ideal for environments where long-lasting credential performance is the primary requirement.
Programmed using 36-bit N901157A formatting, these credentials support structured encoding for secure and scalable access control system deployments. The N901157A format supports a facility code range of 0–255 and card numbering range of 0–67,108,863.
