The HID DuoProx II 1336LGGMN programmed in H10302 37-bit format (no facility code) is designed for access control systems that rely exclusively on a unique card number rather than a combination of facility code and ID. In this format, all available bits are dedicated to the card number, allowing for a significantly larger pool of unique credentials compared to traditional formats like 26-bit. This structure simplifies credential management by eliminating facility code requirements while supporting large user populations across single or multi-site deployments.

The H10302 format is particularly well-suited for systems where card numbers are centrally managed within software, removing the need to track or coordinate facility codes across locations. Operating on reliable 125 kHz proximity technology, the DuoProx II card provides consistent contactless performance while also incorporating magnetic stripe capability for dual-technology environments. This makes it an ideal solution for organizations seeking a streamlined, high-capacity credential format with flexible integration across access control and legacy systems.
