"Digital IDs and Licenses: Which States Offer Them on Mobile Wallets?"
Maryland has become the first state in the US to offer a digital driver's license and ID for Google Wallet, and the first to offer a digital ID on both major mobile operating systems. The mobile driver’s license, or mobile DL, is a digital version of a state-issued ID that is stored on a mobile device. The option to use a digital ID to go through airport security checkpoints is only available at certain airports and only at PreCheck stations.
