HID 925NTNTEK00101 RMK40 Iclass SE HF Reader

HID 925NTNTEK00101 Multiformat Card Reader

Overview

The HID 925NTNTEK00101 is a versatile multiformat card reader designed for access control systems requiring support for multiple credential types and communication protocols. This reader (RDR) with RMK40 mounting bracket delivers broad credential compatibility across enterprise deployments. The 925NTNTEK00101 integrates iCLASS SE contactless technology alongside magnetic stripe and Wiegand output, making it suitable for mixed-credential environments where legacy and modern card formats must coexist on a single door.

Key Features

• iCLASS SE Support: High-frequency contactless card reading with iCLASS SE encryption standard for secure credential verification
• Low-Frequency (LF) Disabled: Reader operates with LF capability turned off, reducing interference and simplifying configuration for HF-only deployments
• Magnetic Stripe Compatibility: Full ABA standard support with all digit capture and 10-digit leading/trailing zeros, enabling magnetic card authentication
• Wiegand Output: Industry-standard Wiegand protocol with terminal support for direct integration to legacy access control panels
• HF Standard/SIO/SEOS Operation: Flexible high-frequency modes including standard iCLASS, SIO (Secure Identity Object), and SEOS (HID SEOS) for credential interoperability
• 4-Bit Messaging: Supports 4-bit message format for streamlined credential transmission and reduced data overhead
• Tamper Detection: Optional tamper switch provides physical security monitoring and alert capability for reader tampering events
• LED and Buzzer Status Indication: Red LED with green flash and buzzer activation for visual and audible read confirmation and system feedback
• Open Collector Output: Open collector configuration enables flexible wiring integration with various access control architectures
• Single-Key Format (BFFRD): Supports buffered facility format single-key operation for streamlined credential processing
• Standard Configuration: Black finish (BLK) with STD-1 standard mounting for rapid deployment in typical access control installations
• No Parity Mode: Operates without parity checking, optimized for credential formats that do not require parity validation

Integration and Compatibility

The HID 925NTNTEK00101 reader integrates with access control systems requiring multiformat credential support. Wiegand output enables connection to traditional access panels, while iCLASS SE support addresses modern credential security requirements. The reader's RMK40 bracket provides standard mounting flexibility. Terminal connections support direct integration without intermediate conversion interfaces. Open collector output allows pull-up configuration to various control voltages, and the optional tamper detection adds physical security monitoring for door frames and reader housing.

Configuration and Operation

The reader operates with low-frequency capability turned off (LF OFF), focusing on HF standard, SIO, and SEOS modes for iCLASS and compatible credentials. Magnetic stripe reading includes full ABA digit capture with leading and trailing zeros (MAG, ABA ALL DGTS + 10 LEAD/TRAIL ZEREOS), enabling support for standard magnetic card formats. The 4-bit messaging format and single-key buffered format (KPF, BFFRD 1 KEY) reduce processing overhead. IPM mode is disabled (IPM OFF), directing all messaging through primary Wiegand and terminal outputs. Red LED with green flash and audible buzzer provide immediate read confirmation feedback to users.

Ted Perry

I evaluated the HID 925NTNTEK00101 during a mixed-credential access control retrofit where the site required support for both legacy magnetic stripe cards and modern iCLASS SE credentials. This reader delivered the multiformat capability the project needed without requiring separate reader channels for each credential type.

Technical Highlights:

• Multiformat Credential Support: iCLASS SE, magnetic stripe (ABA full digit), and Wiegand output in a single reader footprint eliminates need for parallel readers
• HF-Only Operation: LF disabled reduces interference in dense reader deployments and simplifies configuration when legacy low-frequency credentials are not in use
• Standard Protocol Outputs: Wiegand with terminal support ensures compatibility with established access control infrastructure without gateway translation
• Physical Security: Optional tamper detection integrates reader tampering detection into the access control event log for proactive security monitoring

Deployment Considerations:

• Verify access control panel Wiegand input capability and voltage compatibility before installation; open collector output requires proper pull-up configuration for your panel's input specifications
• Confirm credential stock supports iCLASS SE, SIO, or SEOS format if planning exclusive HF operation; mixed deployments benefit from magnetic fallback capability
• Position reader with tamper switch engaged if physical security monitoring is required; verify tamper circuit integration in your access control system event reporting
• Test green flash/red LED feedback during commissioning to confirm visual cues align with user expectations and support door operations staff training

The 925NTNTEK00101 is well-suited for integrators managing credential migration scenarios or facilities with established multiformat card stocks. The combination of HF standard modes with magnetic backup and Wiegand output provides practical interoperability without requiring reader replacement cycles.
