Apple Watch and iPhone owners in the United States will now be able to carry a copy of their U.S. passport on their device, which they can then use at TSA checkpoints across more than 250 U.S. airports when traveling domestically.

Apple’s new Digital ID lets iPhone users verify their identity at TSA checkpoints using passport data — but it’s not valid for international travel.

Apple's new passport-based Digital ID is rolling out on iPhone and Apple Watch — giving travelers a new way to clear TSA security lines with just their device. Why it matters: It's the biggest step yet in the tech giant's push to make the Apple Wallet app a digital replacement for everything in your pocket — from credit cards to car keys to IDs.

Though the new feature allows you to have your passport information at hand, the company has emphasized that it is not a replacement for a physical passport.

The freedom to express their identity is something many in the LGBTQ community are fighting for, says community member Hunter Black.

The Supreme Court agreed to freeze a lower court order that stopped the State Department from enforcing a new passport policy put into place by President Trump earlier this year.
