Digital Passport
A digital passport is a travel credential carried on a phone rather than in a booklet. Under the ICAO framework the formal term is Digital Travel Credential, or DTC, and the defining idea is a split: a virtual component holding the identity data, cryptographically bound to a physical component that is usually the passport you already own.
| Formal name | Digital Travel Credential (DTC) |
| Specified by | ICAO |
| Virtual component | The identity data as a file, stored on a phone or other medium |
| Physical component | The passport chip the virtual component is bound to |
| Data structure | Follows the same Logical Data Structure as the passport chip |
| Type 1 | Derived by the holder from their own passport chip |
| Type 2 | Issued by the passport authority, bound to the physical document |
| Type 3 | Fully independent digital credential — no booklet required |
Not the same as a biometric passport
The terms get used interchangeably and they describe different things.
A biometric passport is a physical booklet containing a contactless chip. The chip is digital; the credential is a piece of paper and polycarbonate you carry in a bag.
A digital passport has no booklet in the transaction at all. The credential is a signed data object on a device. Whether a physical passport exists somewhere in the chain depends on which DTC type you are looking at, and that distinction is the whole architecture.
The three types, and why only one is real yet
Type 1 is derived by the traveler. You read your own passport chip with your phone over NFC, and the app produces a virtual component cryptographically bound to that chip. The passport still exists and still governs; the phone holds a derived copy. This is what pilots have actually run — the Netherlands, among others, has taken travelers through boarding and border control on a Type 1 credential.
Type 2 moves issuance to the authority. The passport-issuing body generates the virtual component and binds it to the physical document. Stronger provenance, because the credential is issued rather than derived, but it requires the issuer to run the process.
Type 3 has no physical component. A fully independent digital credential with its own lifecycle — issuance, renewal, revocation — and no booklet behind it. This is the version that would genuinely replace passports, and it is the one that has not been deployed.
The gap between Type 1 and Type 3 is the honest picture of where digital passports are. Real, running, and still anchored to a physical document.
Why digital passports matter for identity verification
The underlying evidence does not change as much as the form factor suggests. A Type 1 DTC is derived from the same signed data on the same passport chip, verified against the same issuing-country signature. What changes is where the read happens and when.
Two consequences follow. The chip read moves earlier — to the traveler, at home, before the journey — which means the quality of that read matters enormously and is happening on consumer hardware outside anyone’s control. And the binding between credential and person becomes the load-bearing check, because a data object on a phone proves even less about who is holding it than a booklet does.
That pushes weight onto liveness detection and biometric matching against the facial image in the credential. The same pattern the rest of this glossary keeps arriving at: better credentials raise the value of verifying the person, they do not reduce it. For identity document verification the practical work is unchanged in kind and moved in place.
What a digital passport can’t do
Type 1 does not replace the booklet. The passport remains the governing document. A derived credential is a convenience layer over it, not a substitute, and travelers are generally still expected to carry the physical one.
Deployment is thin. Pilots are not infrastructure. Acceptance depends on each destination state having the systems and the legal basis to read the credential.
The derivation step inherits every capture problem. If the traveler’s phone reads the chip poorly or not at all, there is no credential. Device NFC support, damaged chips, and failed key derivation all apply.
It proves the credential, not the holder. A valid DTC on a stolen or shared phone is a valid DTC. Binding it to a person is a separate check, and one that becomes more important rather than less.
Frequently asked questions
Is a digital passport the same as a biometric passport?
No. A biometric passport is a physical booklet with a contactless chip inside. A digital passport is a credential held on a device, which under ICAO’s framework is called a Digital Travel Credential and is usually derived from that chip rather than replacing it.
Can I travel with only a digital passport?
Not yet in general. Deployed pilots use DTC Type 1, which is derived from a physical passport that remains the governing document. The type that would remove the booklet entirely, Type 3, has not been deployed.
How is a Type 1 DTC created?
The traveler reads their own passport chip with a phone over NFC, and an app generates a virtual component cryptographically bound to that chip. The data comes from the same signed source a border reader would use.
What is the difference between DTC Type 1 and Type 2?
Who creates it. Type 1 is derived by the traveler from their own passport. Type 2 is generated by the passport-issuing authority and bound to the physical document, which gives it stronger provenance but requires the issuer to operate the process.
