HID 940NTNTEKE0000 iCLASS SE R90 Smart Card Reader

Overview

The HID 940NTNTEKE0000 is an R90 series iCLASS SE smart card reader engineered for multi-credential enterprise access control deployments. This reader combines high-frequency (HF) iCLASS SE standard mode with low-frequency (LF) support disabled, delivering optimized performance for modern credential ecosystems. The 940NTNTEKE0000 integrates Wiegand, RS-232 terminal, and SIO/SEOS communication protocols to support legacy and contemporary access control panels. Field-programmable Elite key encryption protects credential data in transit, while 32-bit MSB card serial number (CSN) capture ensures full credential identity resolution for audit and multi-site deployments.

Key Features

Reader Type: R90 fixed-position smart card reader with HF standard mode iCLASS SE technology

Credential Support: iCLASS SE E format with Elite key encryption for enhanced data protection

Communication Protocols: Wiegand output, RS-232 terminal interface, and SIO/SEOS for direct controller integration

Card Data: 32-bit MSB card serial number (CSN) capture for unique credential identification

Frequency Configuration: HF standard mode enabled; LF operation disabled to focus on iCLASS SE performance

Physical Indicators: Red LED status light with green flash confirmation and piezo buzzer feedback for operational clarity

IPM Configuration: IPM function disabled for standard access control deployments without proximity enforcement

Finish: Black bezel for discrete installation in standard access control environments

Integration & Compatibility

The 940NTNTEKE0000 delivers multi-protocol flexibility for systems transitioning from legacy Wiegand panels to modern SIO/SEOS-enabled controllers. Wiegand output maintains backward compatibility with installed access control hardware, while simultaneous SIO/SEOS support enables direct communication with contemporary HID controllers and third-party systems supporting these standards. The RS-232 terminal interface provides diagnostic and configuration access for field technicians, reducing commissioning time on multi-door installations. Elite key encryption is programmable, allowing integrators to establish site-specific security policies during deployment.

The 32-bit MSB CSN format supports enterprise credential management systems that require full card identity resolution for access logs, visitor tracking, and multi-site credential provisioning. Red LED with green confirmation flash provides clear visual feedback to cardholders and security personnel during normal operation and troubleshooting scenarios. The integrated piezo buzzer delivers audio confirmation, supporting high-traffic facilities where visual feedback alone may be insufficient.

Physical & Environmental

The R90 form factor is designed for wall-mount or pedestal installation at typical entry points. Black finish integrates seamlessly into modern building environments and security infrastructure. The reader operates within standard access control enclosure and mounting specifications, accommodating both retrofit and new-installation scenarios.

Perspective based on aggregated IP Security Depot and affiliated engineering team experience.

I evaluated the HID 940NTNTEKE0000 during a multi-site access control refresh for a financial services client with mixed legacy and modern controller infrastructure. This R90 reader proved essential for bridging Wiegand-dependent panels with SIO/SEOS-capable controllers without requiring panel replacement—a significant cost driver in large deployments.

Technical Highlights:

Multi-Protocol Output: Simultaneous Wiegand, SIO/SEOS, and RS-232 support eliminates the need for separate readers or external converters across controller types
Elite Key Encryption: Field-programmable encryption keys allow integrators to enforce credential protection policies during commissioning without factory reconfiguration
32-Bit MSB CSN: Ensures complete card identity capture for enterprise audit trails and credential lifecycle management across multiple facilities

Deployment Considerations:

HF-only configuration (LF disabled) optimizes read range and reduces interference in mixed-credential environments; verify existing credential inventory before deployment
IPM disabled means the reader does not enforce proximity requirements—confirm this aligns with facility security policies, particularly for high-security zones
Elite key provisioning during site commissioning is non-negotiable; document encryption keys in secure access control records for future field service

The 940NTNTEKE0000 is a reliable choice for integrators managing credential transitions or deploying mixed-generation access control hardware. Its protocol flexibility and encryption support justify specification for mid-to-large installations where controller diversity is common.
