Galveston County is joining a national project to keep track of children by recording unique characteristics of their irises.
Sheriff Gean Leonard yesterday introduced the county's two new eye-scanners.
Sean Mullin, president of the company that makes the biometric scanners, says a person's iris is unique, like a fingerprint.
Mullin's company -- Biometric Intelligence and Identification -- is working to build a national database of children's eye scans and identification info. The project is working with other missing peoples organizations.
Mullin says the system can scan an eye and match it in the database in seconds.
Galveston County is the first sheriff's department in Texas and the 47th nationwide to join the project.
