Iris Scanning in Jail

Home / Programs / Iris Scanning in Jail

A pioneering new iris-scanning system in Anoka County is quicker and more accurate than a fingerprint.

The Anoka County jail has rolled out an eye-scanning identification system for inmates, a first in Minnesota.  All of the inmates booked into the jail each year will have their irises photographed, and the images will be stored for future use.

A person’s irises are more distinctive than fingerprints, and capturing high-resolution photographs of them and getting back a computer identification takes just seconds.  The Sheriff’s Office saves data on all of the scanned eyes, which are stored in a private and highly secure national database.
