What We Know About TSA’s New Digital ID
Airlines, airports, and TSA aren’t just about boarding passes and baggage anymore — now your phone might be your ID, too. TSA’s new digital identification program is rolling out, and while it promises a smoother, more high-tech travel experience, there are still some important caveats. Here’s what we know so far.
What Is TSA’s Digital ID?
TSA now accepts mobile driver’s licenses (mDLs) and other digital IDs stored in your phone’s wallet (Apple Wallet, Google Wallet, Samsung Wallet) for identity verification at certain airport checkpoints.
The system uses Credential Authentication Technology 2 (CAT-2) readers. These units read the digital ID and take a live photo of you, then compare it to your ID photo.
TSA says only the necessary personal information is shared, making the digital process more private and secure.
You must opt in to facial comparison: if you don’t want a TSA officer to take your picture, you can tell them, and they’ll do a “standard” identity check instead.
Importantly, even if you use a digital ID, TSA recommends still carrying a physical, REAL ID–compliant ID as a backup.
Which States and Airports Are Participating?
Not every state participates yet. As of now, mDLs from states like California, Arizona, New York, Colorado, Georgia, Iowa, Louisiana, Maryland, Ohio, Utah, Puerto Rico, West Virginia, and a few others are accepted.
TSA has expanded to more airports: for example, West Virginia’s mobile ID is now accepted at TSA checkpoints with digital ID readers around the country.
In California (e.g., SMF & SAN), passengers can use their mDL via the DMV Wallet or in their phone’s native wallet.
Louisiana recently joined too: TSA now accepts the LA Wallet app at certain airports.
Why Is TSA Doing This?
Security & fraud prevention: Digital IDs are harder to forge compared to physical cards.
Efficiency: The process can be faster — the CAT-2 reader even verifies that you’re ticketed for a flight that day.
Modernization: This is part of a broader push toward digital identity and “touchless” verification.
REAL ID compliance: TSA’s final rule (from late 2024) allows continued use of mDLs even after REAL ID enforcement began.
Privacy & Safety: What’s the Deal?
TSA says your photo (used for facial comparison) is deleted immediately after verification — it’s not stored long-term for law enforcement or other agencies.
The data shared is limited: only what’s needed to confirm identity. TSA claims this reduces “oversharing.”
Participation in biometric (facial) verification is voluntary. You can opt out.
What Are the Limitations & Risks?
Not universal yet: Because not all states issue mDLs, and not all airports have CAT-2 readers, digital ID won’t always work.
Bring a backup: TSA strongly recommends bringing a physical ID.
User error or agent unfamiliarity: There are reports (including from travelers) of TSA agents not knowing or not accepting digital IDs.
Consent required: You’ll need to agree to send your digital ID info and take a photo. If you decline, you revert to standard ID checks.
State & app support matters: Not all “wallet” apps or state mDLs are supported — check TSA’s list.
Real-World Use: What Travelers Are Saying
Some passengers say the process works smoothly when their phone taps the CAT-2 reader and facial match happens.
Others report confusion: agents aren’t always 100% sure which machines accept digital ID, or they may revert to physical ID if there’s trouble.
In certain airports (especially with less mature rollouts), even if signage says digital ID is accepted, not every checkpoint or line may have the right hardware.
Bottom Line
TSA’s Digital ID program is real, and it's expanding — but it's not yet a universal replacement for your physical ID. If your state supports a mobile driver’s license, and you're traveling through a participating airport, using a digital ID can streamline identity verification. That said, bring your physical, REAL ID–compliant credential just in case.
Tip for travelers: Before your next trip, check TSA’s digital ID page to see if your state and airport support the technology. When you go through, try using the digital ID — but don’t rely on it 100% until it’s widely adopted.
