The Child Project national registry is maintained by the National Center For Missing & Exploited Children, a non-profit based in Phoenix. Once digital photos of the children‘s eyes are made, the data is analyzed and a 688 byte code is created and put into the database. Any law enforcement agency with the proper equipment – which is now prevalent, according to Evangelidis – can easily scan a child‘s eyes and get an identification along with contact information for the child‘s parents.
