The HID 923PPRNEK000CC is a PIV Class smart card reader designed for secure credential verification in access control and identity management applications. This reader integrates into enterprise security infrastructure with support for multiple communication protocols, cryptographic standards, and credential formats required in federal and commercial deployments.
The 923PPRNEK000CC combines hardware-based security architecture with flexible credential handling. Built to accommodate PIV (Personal Identity Verification) Class card specifications, this reader supports both low-frequency and high-frequency operations, enabling compatibility with diverse card technologies across legacy and modern systems. The unit features an integrated LCD display for real-time status feedback and supports multiple wiegand and serial communication options for seamless integration into existing access control panels and readers.
The HID 923PPRNEK000CC integrates with standard access control systems via RS-485 half-duplex serial communication and legacy wiegand protocol support. The open-collector output architecture allows direct connection to door strike controllers and panel inputs without intermediate relays in many installations. LCD display configuration provides local feedback during credential verification, reducing false denials and improving user experience at access points.
The reader's support for FIPS 75-bit encryption and PKI infrastructure makes it suitable for deployments requiring federal security standards or DoD compliance. The combination of CAK and PKI cryptographic modes provides flexibility for both card-based authentication and certificate-based identity verification.
The unit operates with configurable status indicators including red LED indication (standard), green flash for successful reads, and enabled buzzer notification for audio feedback. UART communication is disabled while wiegand protocol is active, supporting single-mode serial operation. The reader's IPM (Intelligent Power Management) is disabled for consistent power delivery in high-traffic environments.
All operations are configured for standard mode with keyboard function (KPF) enabled, supporting manual credential entry and verification workflows. Message handling is configured for 4-bit output with single-key buffer architecture, eliminating parity overhead in credential transmission chains.

I've specified the HID 923PPRNEK000CC in several federal facility access upgrades, and the FIPS 140 compliance combined with PIV Class support makes it a reliable choice for government and regulated commercial deployments. The flexible protocol support—RS-485 serial with wiegand fallback—accommodates both panel modernization and legacy system integration without requiring parallel reader infrastructure.

Deployment Considerations:
The 923PPRNEK000CC's balance of government compliance, multi-protocol flexibility, and robust credential handling makes it a solid anchor point for access control systems serving federal tenants, healthcare facilities, or financial institutions managing PIV or smartcard-based identity programs.
