Some California residents can now carry a digital mobile driver’s license (mDL) under a new app launched by the Department of Motor Vehicles (DMV).

Driving the news: The free pilot, which is limited to the first 1.5 million people who sign up, is intended to allow quick and secure proof of identity while giving people more control over what information they share.

State of play: About two dozen airports currently accept the mDL for TSA PreCheck, including SFO, SJC and LAX. You can also use it to buy age-restricted products at select retail locations in Sacramento via an in-app feature.

• “Usage is not tracked, and no data leaves your device without your consent,” the DMV says on its website.
• It’s built to work with security measures such as Face ID, fingerprint and pin codes. The goal is to lower the potential for fraud and identity theft.
