-USB MK 2120U Basic User’s Guide
4. How many iris images can be stored using the IriSmartEye 2000 software?
A. There is no limitation on the number of images or templates stored for IriSmartEye 2000
purposes on the Host PC. If you create your own Iris Recognition Application for commercial
use or attempt to access other functionalities, certain restrictions may apply. However, the
IriShield
TM
-USB can store 1,000 templates in internal device memory (It can be extended up
to 10,000 templates with a license).
5. How can I check how many persons have been registered?
A. No, this is not possible using the minimal functions available within the IriSmartEye 2000
software. However, you can create your own Iris Recognition Application using the
IriShield
TM
-USB Mono SDK.
6. What is a template?
A. The iris template is a special biometric reference in which the iris features have been stored
for the purpose of matching. Matching compares the stored iris template against the new iris
features extracted from the recently captured iris image data.
7. Can users change the file in which templates are stored?
A. No, this is not possible using the minimal functions available within the IriSmartEye 2000
software. However, you can create your own Iris Recognition Application using the
IriShield
TM
-USB Mono SDK.
8. How long does it take to generate one template?
A. No longer than one second.
9. Is there any limitation of length or special characters when users create IDs associated with an iris
image?
A. Special characters are not allowed, but there is no limitation of the length.
10. If I unenroll the wrong ID by mistake in the IriSmartEye 2000 software, is there any way to restore
the image?
A. An image deleted by the IriSmartEye 2000 software’s Unenroll function cannot be restored.
11. If a user manually deletes the database file, will that achieve the same result as unenrolling all the
registrations?
A. Yes, it will achieve the same result as unenrolling all the registrations, but the IriSmartEye
2000 software will need to be restarted before it will recognize the file as removed.
11.4 Questions about the Image Capture Process
1. Can I capture high quality iris images if the user is wearing glasses or contact lenses?
A. Glasses should not interfere with the image capture, but the iris pattern may be affected by
glare off the glasses depending upon the situation. We recommend the removal of glasses,
especially before enrollment. It is also possible to adjust the equipment as seen in Section
10.5 Preventing Reflection by Glasses to improve the image quality.
