2. Introduction
IriShieldTM-USB MK 2120U camera hardware is a revolutionary, monocular design that delivers the
highest quality auto-capturing iris acquisition with an ease of use never achieved by older camera
systems. The system offers contactless, fast, standards-compliant iris acquisition in a small form factor
that is easy to house in a variety of packages. IriShieldTM-USB includes an embedded CPU that enables
on-board computing for automated quality-based iris image capturing, recognition, and verification
without taxing the computing power of the host PC. IriShieldTM-USB provides a PKI-based security
infrastructure which creates a self-generated RSA-2048bit key and generates a random one-time AES-
256bit key for each session. As a result, this camera can operate with nearly any host PC or mobile
computing device. With its USB interface, compact design, and sophisticated, easy-to-integrate
accompanying software, IriShieldTM-USB represents unprecedented value for iris biometrics
identification.
3. Key Features
All-in-one Iris Identification camera in the ultra-compact size
Top quality, fast, auto-capture and cost-effective iris recognition camera
Automatic, easy-to-use and light-weight
Built-in Real-time Quality Evaluator and Automated Iris Acquisition
Proven leading algorithms for template generation and comparison
Single USB cable connection to host PC (both Power supply and Data)
Powerful SDK for easy software development
Safest for eyes: Safe infrared illumination at less than 2% of the LED Eye Safety Standard
Regulation
Ready to be integrated with IriTech’s enterprise SW environment

order to avoid scratching the optics.
Do not allow water to leak into the device or operate the device in humid conditions where
water might condense upon the electronics.
Do not operate device in places where temperature reach extremes beyond the stated range.
Do not place the device next to heating equipment.
Do not place magnets near the device.
Do not apply voltage or current beyond the stated range.
Do not use the device for any purposes beyond those specified.
Do not disassemble components from the boards or alter wiring or board design.
Do not drop the device or submit to sudden impact or mechanical stresses.
Handle the electronics with proper anti-static protection and techniques to prevent shorting any
microchips.
Any damage to the device caused by these activities will void the warranty.
