You can present your Digital ID in place of a REAL ID at TSA checkpoints using your iPhone or Apple Watch. But Apple notes that it isn’t a replacement for your physical passport, and that you can’t use it for international travel or border crossings.

Travelers can now digitize their passport or eligible driver's license information in their Apple Wallets with a new Digital ID feature that Apple launched Wednesday.

After creating a Digital ID in the Wallet app, you can present it in person at TSA checkpoints in select U.S. airports for age and identity verification purposes during domestic travel.
