The HID ProxKey III Key Fob programmed in H10302 37-bit format (no facility code) is designed for access control systems that prioritize a streamlined, card-number-only credential structure. Unlike traditional formats that divide data between a facility code and card number, the H10302 format dedicates all available bits to the card number itself, creating a significantly larger pool of unique IDs. This expanded capacity makes it ideal for organizations managing large user bases or multiple locations without the need to coordinate facility codes.

By eliminating the facility code, the H10302 format simplifies system administration and reduces the risk of duplication caused by overlapping facility code assignments. It is especially well-suited for systems where credential data is centrally managed within software, allowing for flexible and scalable deployment. Operating on proven 125 kHz proximity technology, this key fob delivers reliable, contactless performance in a compact, durable form factor—perfect for everyday use in commercial, industrial, and institutional environments.
