PIV Card Data Capture

HID Signo PIV & pivCLASS Readers with rf IDEAS® OEM-W2USB-CHUID

This guide covers the hardware components needed to capture PIV card data — CHUID, FASC-N, or GUID — from HID Signo PIV and pivCLASS readers and deliver that credential data to a host computer over USB.

Required Hardware

rf IDEAS® Board

OEM-W2USB-CHUID — Recommended

Wiegand-to-USB converter with support for long-format, 200-bit CHUID output from FIPS 201 / TWIC readers. Translates Wiegand reader output to USB keystroke or callable DLL for software developers. Flash memory is configurable with the free rf IDEAS Configuration Utility.

OEM-W2USB-CHUID — Key Specifications

Attribute	Detail
Model	OEM-W2USB-CHUID
Primary use case	FIPS 201 / TWIC 200-bit CHUID long-format Wiegand output
Interface	USB (HID keyboard emulation or callable DLL)
Configuration	Selectable card data fields via free rf IDEAS Configuration Utility (flash memory)
Form factor	OEM board (Snap-Trak mountable); optional enclosure available
OS support	Any operating system with USB HID support
SDK	Universal SDK available for software developer integration
Reader compatibility	Any Wiegand-output reader; CHUID variant required for 200-bit PIV output

Important: Use CHUID Variant for PIV Deployments

The standard OEM-W2USB-V3 supports common Wiegand formats but is not sufficient for FIPS 201 PIV readers that output 200-bit CHUID data. Always use the OEM-W2USB-CHUID variant in PIV deployments.

Integration Setup — Quick Start

1	Install the HID Signo PIV or pivCLASS reader at the access point. Connect the Wiegand output wires (DATA0, DATA1, GND, +12 V) to the OEM-W2USB-CHUID board’s Wiegand input terminals.

2	Power the OEM-W2USB-CHUID board via USB from the host computer. The board draws power from USB; the HID reader requires a separate 12 V supply per manufacturer specifications.

3	Install the rf IDEAS Configuration Utility version 4.4.6 (free download at rfideas.com). Use it to select which CHUID data fields to output, set output order, and add any prefix/suffix keystrokes.

4	Verify CHUID output by opening a text editor on the host and presenting a PIV card to the reader. The decoded CHUID fields should appear as keystrokes at the cursor. Confirm field format matches your application requirements.

5	Integrate with your application via keystroke input or the rf IDEAS Universal SDK (callable DLL) for programmatic access. The SDK supports all major programming environments.
