Introduction to the EF-45N™ Iris Recognition System
This new iris recognition system offers highly intuitive, hands-free iris biometrics imaging
in a compact and elegantly designed identification and authentication terminal for use in
a wide range of identity management applications.
The front facing nominal 5.0 inch LCD serves to display
the user’s face image for fast, easy and highly natural
positioning for proper iris image capture. The subject
merely puts his or her face in the center of the LCD, and
then moves toward the system to size his or her head to
the brackets in the display to be in proper range. Image
capture is fast and automatic. While user instructions
are very simple, almost all subjects will be able to
interact with the system without any directions.
And the internal automatic tilt mechanism adjusts to the user’s height or vertical position
over a range of 50 cm (about 20 inches), making the EF-45N ideal for countertop,
desktop, wall mount or kiosk installations.
The EF-45N is an embedded terminal, which means that all image processing and
machine control is performed on the internal Linux-on-ARM mainboard. Typical
connectivity to host systems is through TCP/IP (Ethernet). And iris biometric encoding
and matching is typically performed on-board as well, so identification or authentication
decisions are made locally for fast responsiveness. For access control, there are Wiegand
connections for dedicated, local communications to door controllers or panels.
Other typical options include WiFi and a smart card reader.
For all specifications, please see Specification section.

and On-Board Demo Application” manual.
