The Santa Fe New Mexican reports the change adopted this week will require parents and visitors to campus to show IDs so officials can check their backgrounds. A system will conduct a quick scan to make sure the name and birthdate on the visitor’s driver’s license do not match any information logged in a national sex offender list.

Under the new system, visitors must swipe their driver’s license or another type of identification card through a device that looks similar to a credit card machine.

Santa Fe Public Schools spokesman Jeff Gephart says the change will add “an additional layer of safety.”
