The EF-45Nc next generation iris recognition system provides unprecedented subject ease of use through a highly innovative and intuitive user positioning approach. Subjects will view their own face in a front-facing, high resolution 5.0 inch color display to position themselves correctly within the real-time graphic interface. They will intuitively and naturally move to the correct position by sim- ply centering and sizing their face image to the box within the display. In addition, the position- ing box and the top border turn green to indicate proper distance positioning, after which the iris biometrics images are automatically collected, provided that the real time image quality metrics are satisfied. Vocalized commands give additional positioning guidance in real time.

New for the EF-45Nc, a time-of-flight (TOF) proxim-ity and distance sensor is integrated for fast and precise detection of all subjects. The system now features a faster tilt motor, and proprietary “deep learning” based face detector algorithm. Together, the system is faster, smooth- er and even more intuitive than ever before. The deep-learning face detector also enhances opera- tion in bright ambient light for deployment posi- tioning flexibility. Now, capturing highest quality iris biometrics images is fast, simple and fully intuitive for all subjects, including non-acclimated ones.

The EF-45Nc operates at an expansive capture range of 35 to 45 cm in enrollment mode. In rec- ognition mode, the capture range is extended to 32 to 45 cm, further increasing positioning flexibil- ity and ease of use.

The system captures high quality face images simultaneously with iris image capture. On board face recognition is optional.

The EF-45Nc is an embedded system that includes its own Quard mainboard to manage all face and iris imaging processes.

The normal external communication to host systems and clients is through TCP/IP via an Ethernet connection, but USB connectivity to a local PC host is available. The embedded architecture allows for on-board iris and face template generation and matching against a local data base. The EF-45Nc is offered in two basic hardware configurations: the AC version is for physical access control (PACS), time & attendance and similar applications, and includes an embedded MiFare card reader, a wall mount bracket and a full set of I/O connectors; the ID version is for general identity management applications and does not include the card reader or the full connector set.

The EF-45Nc is fully backward compatible with the prior generation EF-45 system, which means that no API changes are required for systems integrators.

Innovative, Intuitive Subject Positioning

The EF-45Nc’s TOF sensor detects subjects from over 1.0 meter from the system; the subject’s face is immediately displayed on the 5.0 inch high resolution color display. For proper positioning, the subject will naturally center his face by simply making his or her face fit the positioning “guide box”. Vocalized instructions also command the user to move forward or back to get into range. When in the proper range, the guide box and top border turn green, indicating to the subject to stop and wait until the image capture process is completed. Like a smart phone “selfie” image, this interface is highly intuitive, with typical capture times of 0.5 seconds from proper positioning.

Key Features

Feature	User Advantages
State-of-the-art optical design	The optical design includes utilizing highest quality optics and very fast shutter speeds, which allows the systems to exceed industry standards for image quality.
Advanced, proprietary stereoscopic eye localization	The EF-45Nc accurately locates the position of both eyes in 3D to optimize subject ease of positioning and iris image quality. This function enables the fast and reliable subject distance positioning indicators shown as blue, green or red color distance positioning codes.
Highest image quality	Meets or exceeds the ISO 19794-6 2011 and ISO 29794-6 iris imaging specifications.
Compact, lightweight design	Optimizes placement or mounting options, including wall, swing arm, or eGate mounting solutions.
Simplest of user instructions	Very simple and repeatable subject instructions: • Position face within guide box in display (like smartphone “selfie”) • Move toward the system to size head to box • Once within range, the box and indicator bar will turn green to indicate proper positioning Capture is automatic once subject is in proper position and real time image quality metrics parameters are met.
Stand-off distance and depth of capture in enrollment mode	35 to 45 cm, ensuring robust, fast and easy positioning. Comfortable range for subjects in wide variety of desktop, countertop, kiosk or wall mount placements.
Extended depth of capture in recognition mode	Depth of capture can be extended to a range of 32 to 45 cm in recognition mode (not necessarily ISO compatible). Intended for small to medium scale access control deployments. Selectable in SDK.
Real time image quality metrics	Image quality metrics included in capture algorithm: • Subject gaze angle (i.e. whether the subject is looking directly ahead at the imager) • Subject motion • Focus • Usable iris area (occlusion)
Face image capture	A face image is always collected at same time as capture of iris images, so that the data record consists of one face image and two iris images. Note: the face images do not qualify as ISO standard, and therefore are not intended for large scale face recognition purposes. They are intended for small scale face recognition and manual verification of the subject’s identity. Face images also remain in the log file to visually verify who was authenticated.
Face recognition	Optional. Contact CMITech for algorithm selection and pricing.
Very wide interpupillary distance range	The wide interpupillary distance range accommodates all adults and young children, making it ideal for large scale, public authentication programs.
Large on-board data bases for on- board identification and authen- tication	Standard on-board (local) iris data base of 100,000 subjects (iris template-pairs), with matching speed of about 0.5 second in 1:N mode.
Template-on-card	Supported for MiFare and DesFire cards
Cable connectors	For AC version, plug-in connector kit for all cabling (except RJ-45 Ethernet) included in accessories package.
WiFi	Optional, field installable WiFi dongle for ease of networking installation. (Contact CMITech for WiFi dongle specification for each country).
Card reader	Standard in AC version only: embedded MiFare card reader for support of dual factor authentication, or backup authentication for special case users.
Language support	Display languages of English, Korea, Traditional Chinese, Simpli- fied Chinese, Japanese, Spanish, Italian, Arabic, and Russian. Vocalizations for positioning can be modified by local systems integrators through modification of on-board .wav files.
