he HID ISOProx Proximity Card programmed in H10302 37-bit format (no facility code) is designed for access control systems that utilize a simplified, card-number-only credential structure. Unlike standard formats that rely on both a facility code and card number, the H10302 format allocates all available bits to the card number itself, creating a substantially larger pool of unique credentials. This expanded numbering capacity makes it an ideal solution for organizations managing large user populations or multi-site systems without the limitations of traditional format structures.

By eliminating the facility code, the H10302 format reduces administrative complexity and minimizes the risk of duplication caused by overlapping facility code assignments. It is particularly well-suited for systems where credentials are managed directly within software, allowing for flexible assignment and scalability. Operating on proven 125 kHz proximity technology, these cards deliver consistent, contactless performance and dependable durability, making them a reliable choice for commercial, institutional, and enterprise access control environments.
