(KTRS) – Starting in two weeks visitors to Scott Air Force Base will need more than a Missouri drivers license to get onto the property.

The change is required by the REAL ID Act of 2005. The goal of the legislation was to stop would-be terrorists from getting false credentials by forcing states to issue more secure ID cards. Missouri has yet to comply with the standards.

Without another acceptable form of ID–like a passport–visitors will be turned away or must have an escort their entire time on base.

The Department of Homeland Security previously said that Missourians will be able to use their current state-issued IDs to board plans until 2018.
