Iris Recognition Device | Iris Biometric Device
Product Description
IRIS Recognition Device TW-EF45’s next-generation dual iris imaging 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 simply centering and sizing their face image to the box within the display. In addition, the positioning 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.
In addition, this system features an expansive capture range of 35 to 45 cm in enrollment mode. Now, capturing the highest quality iris biometrics images is fast, simple, and fully intuitive for all subjects, including non-acclimated ones. For small-scale access control or time & attendance applications, the capture range can optionally be extended to 30 to 45 cm in recognition mode, further increasing positioning flexibility and ease of use.
The system also captures high-quality face images simultaneously with iris image capture. On-board face recognition is standard.
The TW-EF45 is an embedded system that includes its own ARM 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 onboard iris and face template generation and matching against a local database.
The TW-EF45 is offered in two basic hardware configurations: the TW-EF45AC version is for physical access control (PACS), time & attendance, and similar applications, and includes an embedded MiFare card reader plus a wall mount bracket and a full set of I/O connectors; the TW-EF45ID
version is for general identity management applications, and does not include the card reader.
A Wifi Option is available.
Innovative, Intuitive Subject Positioning
The TW-EF45’s face imaging sensor detects and displays the subject’s face at up to 1.0 meters from the system on the high-resolution color display. The subject will naturally move toward a capture range of up to 45 cm by simply making his or her face fit the positioning “guide box”, which is the capture or focal range of the system.
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 smartphone “selfie” image, this interface is highly intuitive, with typical capture times of less than 1.0 seconds from proper positioning.

Comparison Between Face Recognition and IRIS Recognition
| Facial Recognition | IRIS Recognition Device |
| Non-invasive, the subject is not requiring contacting the equipment for presenting the biometric sample | Highly invasive, the subject needs to keep his/her eye stead on equipment optics while providing sample |
| Low distinctiveness: facial characteristics may repeat in people,e.g in twins | Highly distinctive: iris patterns do not repeat in individuals |
| Low accuracy | High accuracy |
| Only for small Databases | Ideal for handling large Databases: Iris recognition is the only biometric authentication technology designed to work in the 1 -n or exhaustive search mode. The maximum number of users of TW-EF45 are 50,000 |
| Subjects can be identified from a distance | The subject can not be identified from the distance |
| Medium permanence and stability may get affected by age or facial surgery | With low permanence and stability, it may get affected by certain diseases |
| Low security and low confidence level | High security and high confidence level |
| Highly collectible, highly exposed due to location of face and larger details – It may cause the privacy concerns | Low collectability, details are inside the eye |
| High universality: facial features are found in all human beings | Medium universality |
