A mobile ID is a government-issued digital version of your driver’s license or state identification card that lives on your smartphone and can be verified electronically. Mobile identification, often called a mobile driver’s license or mDL, is issued by your state’s motor vehicle agency and cryptographically signed so that a reader device can confirm the credential is genuine and unaltered. More than 20 states and territories now offer some form of digital ID, and roughly 100 million mDLs are projected to be in circulation across the country during 2026. In almost every state, you still need to carry your physical card as well; the digital version is a companion, not a replacement.
Why a Mobile ID Is Not Just a Photo of Your License
A screenshot of your plastic card has no security value. A mobile ID does, because it’s built on an international standard called ISO/IEC 18013-5, which defines how digital driver’s licenses are structured, encrypted, and transmitted to reader devices.1International Organization for Standardization. ISO/IEC 18013-5:2021 – Personal Identification – ISO-Compliant Driving Licence – Part 5: Mobile Driving Licence (mDL) Application The credential is cryptographically bound to both your issuing authority and your specific device. A verifier reading it can confirm two things at once: the data came from a legitimate state agency, and nothing in it has been tampered with.2National Institute of Standards and Technology.

The standard also controls how the data moves. Your phone communicates with a reader through Near Field Communication (a short tap) or by displaying a QR code for scanning.3Transportation Security Administration. Digital Identity and Facial Comparison Technology The transfer is encrypted, the protocol blocks cloning, and your phone never leaves your hand. None of this is possible with an image file, which is why TSA agents, retailers, and other verifiers that accept mDLs will only accept them through a standards-compliant app or wallet.
Where Mobile IDs Are Available and on Which Phones
As of mid-2026, the TSA lists digital IDs from over 20 states and territories as accepted at airport security checkpoints, including Alaska, Arizona, Arkansas, California, Colorado, Georgia, Hawaii, Illinois, Iowa, Kentucky, Louisiana, Maryland, Montana, New Mexico, New York, North Dakota, Ohio, Puerto Rico, Utah, Virginia, and West Virginia.4Transportation Security Administration. Participating States and Eligible Digital IDs Additional states have programs in development. Whether you can get one depends on where your license was issued and which wallet platform your state has chosen to support.
The main platforms are Apple Wallet, Google Wallet, Samsung Wallet, and state-specific apps. Coverage is uneven. Iowa and California, for instance, support both a dedicated state app and the major wallets; other states support only one. Check your state’s motor vehicle agency website before you try to enroll.
Your phone has to meet the platform’s requirements. On the Apple side, that currently means an iPhone 8 or newer running at least iOS 16.5, though some states require newer models.5Apple. Add Your Driver’s License to Apple Wallet Google Wallet and Samsung Wallet have their own device thresholds that vary by state. The phone also needs biometric unlock (fingerprint or face recognition), because you authenticate that way every time you present the credential. You’ll need an internet connection during setup; once provisioned, many verifications work offline.
What You Need Before You Enroll
Start with a valid, unexpired physical driver’s license or state ID from a participating state. The mDL is created from the data on that card, so a suspended, expired, or flagged license will cause enrollment to fail. If the address or other details on your physical card don’t match your current information, fix that with the DMV first. Mismatched records are a frequent reason applications get rejected.
Your underlying card also has to be REAL ID-compliant or an Enhanced Driver’s License for the mDL to be accepted at TSA checkpoints.6Transportation Security Administration. REAL ID Mobile Driver’s Licenses (mDLs) Most states charge nothing extra for the mobile version beyond what you already paid for the plastic card.
How to Set One Up
Enrollment happens on your phone through your state’s app or a built-in digital wallet. You photograph the front and back of your physical card. The app runs optical character recognition on the images and checks the extracted data against your state’s motor vehicle records. Lighting matters at this step. Glare on the card’s holographic features is the single most common reason scans fail the first time.
Then comes the liveness check, which is what separates a real enrollment from someone uploading a stolen photo. The app opens your front camera and may ask you to turn your head or blink. It confirms a live person is holding the phone and that your face matches the photo the state has on file. Poor camera quality or bad lighting can cause the check to fail. Some states also ask you to type in supplemental data, like the audit number printed on your physical card.
Processing time varies. Some states push the credential to your device within minutes. Others take a business day or two for staff review. You’ll get a notification when the mDL is live.
How You Present a Mobile ID
At a TSA checkpoint, you either tap your phone against an NFC reader or display a QR code for the agent to scan.3Transportation Security Administration. Digital Identity and Facial Comparison Technology You don’t hand over the phone. The reader requests only the specific fields it needs, and your phone shows you exactly what’s being asked for before anything transmits. You approve the share with a fingerprint or face scan, and the data moves across the encrypted channel to the verifier.
The reader then signals to the agent that the credential is valid and that it belongs to you. That’s generally faster than a visual check of a plastic card under fluorescent lighting. If verification fails for any reason, you’ll be asked for your physical card as backup, which is why every state with an mDL program still tells residents to carry it.7Department of Revenue – Motor Vehicle.

Keep the phone charged. A dead battery means no ID for that interaction. At a traffic stop, that could mean a citation for failure to present a license, depending on your state. It’s the single most practical weakness of going digital.
Privacy and Selective Disclosure
Mobile IDs can share less information than a plastic card. A bartender who takes your physical license sees your full name, date of birth, address, license number, and everything else printed on it. An mDL built on ISO 18013-5 supports selective release, meaning you can share only the fields the verifier actually needs.1International Organization for Standardization. ISO/IEC 18013-5:2021 – Personal Identification – ISO-Compliant Driving Licence – Part 5: Mobile Driving Licence (mDL) Application
For an age check at a bar, the reader can request only a yes-or-no confirmation that you’re over 21 without ever seeing your address or license number. AAMVA’s implementation guidelines distinguish between data minimization at the issuing authority (fractional fields like birth year alone) and selective release at your device (what you actually agree to send). Both happen before any data leaves the phone.
The standard also includes anti-tracking protections. Device public keys rotate and randomize so that different verifiers can’t correlate your transactions and build a profile of where you’ve been. An optional flag tells you when a verifier intends to store your data, so you can decline. None of this exists with a plastic card. Once the plastic leaves your hand, the other party sees everything on it and you have no way of knowing whether they photographed or recorded it.
Does Showing a Mobile ID Let Police Search Your Phone?
No. The U.S. Supreme Court held in Riley v. California that police generally cannot search the digital contents of a cell phone without a warrant, even during a lawful arrest.8Justia U.S. Supreme Court. Riley v. California, 573 U.S. 373 (2014) Presenting an mDL doesn’t change that. The transaction is designed so the officer interacts with a reader, not with your phone’s operating system, apps, or files. Data moves through a dedicated encrypted channel. You’re never required to hand the phone over for an mDL check, and the ISO standard was built specifically to keep the device in your possession throughout verification.
REAL ID Still Applies
REAL ID enforcement began on May 7, 2025. Since then, boarding a domestic flight or entering certain federal facilities requires a REAL ID-compliant license, an Enhanced Driver’s License, or another acceptable form of identification such as a passport.9Transportation Security Administration. REAL ID Travelers who arrive without acceptable ID may face extra screening and a $45 fee.
A mobile ID doesn’t let you skip this. The mDL you present at a TSA checkpoint has to be based on a REAL ID-compliant physical license or an Enhanced Driver’s License from an approved state.6Transportation Security Administration. REAL ID Mobile Driver’s Licenses (mDLs) If the underlying card isn’t compliant, the digital version isn’t either. States also have to apply to the TSA to get their mDL programs federally approved, and only approved programs appear on the TSA’s participating list.
