Schlage Electronics 8843T37XFC100 Thin Fob 37X FC100

Product Description

The SCHLAGE ELECTRONICS 8843T37XFC100 is a thin proximity fob that combines standard 125 kHz proximity technology with MIFARE DESfire EV3 4K byte smart card capability in a single credential. Operating on the 37-bit format with Facility Code 100, this fob is designed for electronic access control systems in commercial, multi-family, and institutional applications. The compact form factor measures 2 inches in length, 1.5 inches in width, and 0.5 inches in height, making it well suited for everyday carry on a keyring. Access control technicians and security integrators are the primary installers and programmers of this credential.

This fob is intended for use in access control deployments that require dual-technology credentials supporting both legacy proximity readers and newer MIFARE DESfire EV3-compatible smart card readers. The 37X format with pre-programmed Facility Code 100 suits sites that have standardized on that facility code across their reader infrastructure. It is sold under the Card Trax CT7X4868 cross-reference and must be purchased in multiples of 50 units per order. Typical installations include office buildings, apartment complexes, healthcare facilities, and campuses where a unified credential platform is required.

Installation Notes

This credential is programmed at the factory and does not require on-site encoding for standard proximity operation. Access control technicians should verify that the installed reader infrastructure supports both the 37X bit format and the MIFARE DESfire EV3 protocol before deploying these fobs. No tools are required to issue the fob to an end user, but reader enrollment or programming at the access control panel should follow the system manufacturer's procedures. Confirm facility code alignment with the existing credential database before placing a bulk order.
