The Transportation Security Administration (TSA) in Maryland will now accept Maryland-issued mobile driver's licenses from Google Wallet at security checkpoints. TSA PreCheck passengers will be able to use this new feature at checkpoints for identity verification at 25 participating airports.  

Other states have utilized mobile driver's licenses in TSA, though they're often limited to Apple users. The passenger may consent to provide their mobile identification from Google Wallet by turning on Bluetooth and holding their Android smart phone or watch on the Credential Authentication Technology (CAT-2) reader device. The digital identity information from the mobile driver’s license is encrypted and transmitted digitally to CAT-2, where the passenger’s real-time camera photograph will be compared against the encrypted mobile identity information from Google Wallet and their reservation data that would have been on the passenger’s boarding pass.
