Few people find themselves unable to use the technology. In a few instances even blind persons have used iris recognition successfully, as the technology is iris pattern-dependent, not sight dependent.

Structural formation in the human iris is fixed in early childhood and remains constant over a lifetime. So once a individual is enrolled, re-enrollment requirements are infrequent.

Iris recognition is the only biometric authentication technology designed to work in the '1-n' or exhaustive search mode, making it ideal for handling applications requiring management of large user groups, such as the VAXSYS System database.

In 'one to many' search mode, iris scans are unmatched by other authentication technologies. In a recent study, Iris ID’s IrisAccess platform searched records nearly 20 times faster than the next biometric technology: up to 10 million+ matches per second.

While initially designed to work in 'one-to-many' search mode, iris recognition works well in 'one-to-one' matching, or verification mode. This makes the technology ideal for use in multi-factor authentication environments where PINs, or tokens are used.

Using 512-byte encryption, Iris ID iris scans cannot be re-engineered or reconstituted to produce any sort of visual image. As such, Iris recognition provides a high level defense against identity theft, with an imaging process that involves no lasers or bright lights. Iris scans are essentially non-contact.

Using Iris Scan Technology is intuitive, requiring minimal cooperation from subjects. Proximity sensors activate the equipment, which incorporates mirror-assisted alignment functionality. Audio auto-positioning prompts, automated image capture, and visual and audio authentication decision-cueing completes the process.
