HID 940NTNTEK000K4 RP10-H Pivclass SE LF HF Reader

HID 940NTNTEK000K4 iCLASS SE Smart Card Reader

Overview

The HID 940NTNTEK000K4 is a compact, multi-protocol smart card reader designed for access control installations requiring flexible credential support and multiple communication options. Built on the iCLASS SE platform, this reader combines high-frequency (HF) and low-frequency (LF) credential recognition into a single endpoint, eliminating the need for separate reader infrastructure while maintaining robust security through standard encryption protocols.

The 940NTNTEK000K4 accommodates iCLASS credentials and supports HID's established ecosystem of card technologies, making it suitable for retrofit and new deployments where credential flexibility is essential. Its terminal and Wiegand output modes enable seamless integration with existing access control panels, while custom audio-visual signaling provides audible and visual feedback for installation technicians and end users.

Key Features

• Dual-Frequency Credential Support: Supports HF standard, SIO, SEOS, and Mifare proprietary (MIFSPR) protocols, with LF capability switched off for simplified credential management
• Multiple Output Protocols: Wiegand output with standard terminal mode, ensuring compatibility with legacy and modern access control systems
• iCLASS SE Technology: R90 reader platform provides secure credential encoding and mutual authentication to prevent cloning and unauthorized access
• Card Security: CSN (Card Serial Number) Mifare suppression enabled to enhance security during credential transactions
• Audible & Visual Feedback: Red LED indicator with flash disabled and audible buzzer set to ON, confirming successful reads and reader status for installers
• Black Bezel Housing: Standard finish in black (BLK) for seamless integration into building security infrastructure
• Configurable Signaling: Custom audio-visual output options with LED and buzzer control for site-specific deployment requirements
• Compact Terminal Mounting: Standard-1 (STD-1) enclosure format enables wall-mount or surface installation in controlled access points
• IPM Function Disabled: IPM switched off to streamline reader operation in single-technology credential environments

Integration and Compatibility

The 940NTNTEK000K4 integrates with access control panels supporting Wiegand input and traditional terminal connections. Terminal mode output allows direct connection to controllers using legacy contact-closure protocols, while Wiegand output (26, 34, or 37-bit formats) connects to systems expecting serial card data transmission. The reader's HF standard and SEOS support aligns with HID's iCLASS ecosystem, enabling multi-site credential programs where organizations operate mixed reader populations. Custom audio-visual configuration allows integrators to set red LED and buzzer behavior during deployment to match site security procedures and user experience requirements.

The CSN Mifare suppression feature ensures that reader output does not expose card identifiers vulnerable to relay attacks, enhancing the security posture of access points processing sensitive credential data. This configuration is particularly relevant in environments where card cloning or unauthorized credential reading represents an operational risk.

James Everett

I evaluated the HID 940NTNTEK000K4 during a phased access control modernization project where client facilities required credential flexibility without wholesale reader replacement. The iCLASS SE R90 platform on this unit delivered the authentication robustness our security team required while preserving Wiegand compatibility with existing panel infrastructure.

Technical Highlights:

• Credential Protocol Mix: HF standard, SIO, SEOS, and Mifare proprietary support with LF disabled provides focused credential processing; simplifies inventory and reduces reader configuration complexity in sites transitioning away from legacy LF-only systems
• Output Flexibility: Dual-mode Wiegand and terminal output enables connection to controllers supporting either protocol; no protocol conversion gateway required in many retrofit scenarios
• Security Control: CSN Mifare suppression prevents raw card number leakage during reader-to-panel communication; critical mitigation in shared-access facilities or environments with repeated credential scanning

Deployment Considerations:

• Confirm access panel Wiegand input specification (26, 34, or 37-bit format) before installation; terminal mode offers fallback for legacy contact-closure controllers lacking Wiegand support
• Audio-visual feedback configuration (red LED, buzzer ON) benefits installation verification but should be tested against site ambient noise and lighting conditions to ensure user feedback is perceptible
• HF-only operation (LF OFF) streamlines credential issuance but precludes reading legacy low-frequency cards; validate end-user credential stock before deployment

The 940NTNTEK000K4 performs reliably in access control points where integrators require iCLASS SE platform security with pragmatic output compatibility. Straightforward Wiegand or terminal connection, combined with configurable signaling, positions this reader as a solid option for facilities consolidating credential types and modernizing reader infrastructure incrementally.
