The HID 922NTNNEK00075 is a multi-technology smart card reader designed for secure access control integration across enterprise and facility environments. This reader combines iCLASS SE credential support with legacy magnetic stripe and low-frequency capabilities, making it suitable for phased technology transitions or mixed-credential deployments. The RM40 form factor delivers a compact footprint for wall or desktop mounting, while its open-collector output architecture and Wiegand communication protocol ensure broad compatibility with existing access control systems and panels.
The HID 922NTNNEK00075 integrates directly into access control systems using standard Wiegand readers input. The open-collector architecture supports both 5V and 12V control environments common in institutional and commercial installations. Magnetic stripe, low-frequency, and high-frequency credential modes operate independently, allowing integration with single or multi-credential system deployments. The reader's raw output capability ensures compatibility with legacy access control panels that process unformatted credential data.
Tamper functionality is optional, enabling deployment in either open or monitored configurations. The combination of Wiegand protocol, open-collector switching, and multi-technology credential support positions the 922NTNNEK00075 as a bridge solution for facilities transitioning from magnetic stripe or proximity card systems to modern smart card infrastructure.

I've specified the HID 922NTNNEK00075 in several enterprise access control refreshes where existing magnetic stripe infrastructure needed to coexist with iCLASS SE smart card deployments. The multi-technology reader approach eliminates the need for dual readers at each access point, reducing cabling and control panel I/O consumption.
Technical Highlights:
Deployment Considerations:
The 922NTNNEK00075 is a reliable choice for mixed-credential environments and technology transitions. The open-collector architecture and native Wiegand support make it one of the most flexible readers available for integrators managing heterogeneous access control infrastructures.
