Description
HID 1346LNSMN ProxKey III Key Fob
48-Bit Format
The HID ProxKey III Key Fob programmed in 48-bit format is designed for organizations that require an exceptionally large credential numbering capacity while maintaining compatibility with proven HID 125 kHz proximity technology. By dedicating additional bits to credential identification, 48-bit formats provide a significantly larger pool of unique card numbers than traditional 26-bit and 37-bit formats, making them ideal for enterprise, government, healthcare, education, and multi-site deployments.
The expanded numbering structure helps reduce the risk of duplicate credentials while simplifying large-scale credential administration. Organizations managing multiple facilities, thousands of users, or long-term credential issuance programs often select 48-bit formats to maximize scalability and future growth.
Built on HID's trusted ProxKey III platform, these compact key fobs are small enough to fit comfortably on a key ring while providing reliable contactless access through compatible HID proximity readers. The rugged construction is designed to withstand daily use in demanding commercial and industrial environments. HID ProxKey III credentials support formats up to 85 bits and are backed by HID's lifetime warranty. :contentReference[oaicite:1]{index=1}
