What's REAL ID?  It's an enhanced driver's license and if you don't have one by this time in 2020, you won't be able to board a commercial flight without another form of ID such as a US passport.

KSFY is reporting that South Dakota has its REAL ID system in place and ready to go.

Minnesota one of the last hold outs in the country to enact the new system.  Less than 10 percent of Minnesotans have a REAL ID.  Residents have one year to get in the system if they wish to fly without showing another form of ID.

David Wrigg with the Minnesota Driver's License Department in Luverne says, "People have to prove who they are and they live where they say they live."

KSFY reports Minnesotans to need to provide an official form of identification such as a birth certificate or social security card to get a REAL ID, in addition to a couple of different documents proving current residency.

Iowa is also behind schedule on implementing the REAL ID program.
