The deadline to get a Real ID is coming up next month, yet millions of Americans still don't have one. From May 7, US citizens who plan to fly to domestic destinations, or visit government buildings, will need one of the IDs.
The change has been implemented as a way of improving security on domestic flights, as these IDs are more secure and harder to fake than other documents.
However, the Transportation Security Administration (TSA) told CBS News that only 81% of passengers are complying with the regulation ahead of the deadline, showing either a passport or Real ID when they go through security.

This could mean another two in ten Americans still don't have the required ID. TSA spokesperson Patricia Mancha, told CBS: "Everybody is responsible for presenting the proper travel documents when they come to the checkpoint".
When the May 7 deadline hits, Patricia said passengers without the correct ID could take longer to get through security: "there's going to be a phased approach of enforcement, but people may experience travel delays."
Passengers who don't get a Real ID ahead of the deadline will be able to use a valid passport or military ID. Residents of Michigan, Minnesota, New York, Vermont or Washington State, can also use an Enhanced Driver’s License or Enhanced ID.
Under 18s won't need a Real ID, as domestic US flights don't usually require minors to have ID, although the adult responsible for them will need valid documents.
The Department of Motor Vehicles (DMV) are issuing Real IDs, which will still be available after the May 7 deadline. The DMV will need to see a form of ID such as a passport or birth certificate, proof of social security number, and two items of proof that show you live in the state.
Check with your local DMV for any specific requirements ahead of your appointment.
According to CBS, the looming deadline has also meant a rush to book DMV appointments, with scalpers in Florida booking up free appointments, and trying to sell them on for as much as $250.
In response to the demand, Illinois opened a Real ID supercenter, located in an old Walgreen's. They've been able to process applications for up to 1,500 people a day.
The Real ID Act first passed in 2005, as a response to the 9/11 attacks. However, the deadline for enforcing the new ID has been repeatedly delayed until this year. Real IDs have higher security standards, and feature a star in the top right corner.
