Introduction to the EF-45 Iris Recognition System
The EF-45 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 5.0inch 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 positioning box at the
top of the LCD, and then moves toward the system to
size his or her head to the box 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 direction.
The capture range is a robust 35 to 45 cm, also contributing to the system’s ease of
use. There is an optional “fast capture mode”, in which the range is further extended to
30 to 45 cm, although in this mode, images may not conform to ISO 19794-6 2011 or
ISO 29794-6 standards.
And the internal automatic tilt mechanism adjusts to the user’s height or vertical
position over a range of 40 cm (about 16 inches), making the EF-45 ideal for wall
mount, countertop, desktop, or kiosk installations.
The EF-45 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 can be made locally for fast responsiveness. For access
control, there are Wiegand connections for dedicated, local communications to door
controllers or panels.
Other options include WiFi and extended on-board data base (to 40,000 users), and a
smart card reader (in the AC version).
