 If your state is, then to use a digital ID, you add your state issued driver's license or identification card to your phone using a TSA approved digital ID app or to your digital wallet. This ID will be used at the TSA screening point in place of your physical driver's license and boarding pass. A picture of you will be taken and compared with your license. With TSA secure flight system technology, they can verify you are ticketed that day for air travel. Photos and biographic info will be deleted from the devices after the TSA transaction.
