From "Apple launches the first driver’s license and state ID in Wallet with Arizona" posted Wednesday in the Apple Newsroom:
Starting today, Arizonans can add their driver’s license or state ID to Wallet, and tap their iPhone or Apple Watch to seamlessly and securely present it at select TSA security checkpoints in Phoenix Sky Harbor International Airport.
“We’re thrilled to bring the first driver’s license and state ID in Wallet to Arizona today, and provide Arizonans with an easy, secure, and private way to present their ID when traveling, through just a tap of their iPhone or Apple Watch,” said Jennifer Bailey, Apple’s vice president of Apple Pay and Apple Wallet. “We look forward to working with many more states and the TSA to bring IDs in Wallet to users across the US.”
Additional states will offer driver’s license and state ID in Wallet soon. Colorado, Hawaii, Mississippi, Ohio, and the territory of Puerto Rico plan to bring this feature to their residents, along with the seven states Apple previously announced.
My take: One state at a time.
