Passport Photo for Digital ID & eID Wallet 2025/2026
Digital identity wallets are changing how we authenticate ourselves online and at physical locations — but they all still start with a physical identity document. This guide explains what passport photo you need for the EU Digital Identity Wallet (eIDAS 2.0), the German eID, Austrian ID Austria, the Swiss eID, and the UK digital driving licence, and how your photo becomes a chip-stored biometric.
Key point
Digital ID wallets are linked to a physical identity document (passport or national ID card) that must be obtained first through the standard process — which requires a compliant ICAO biometric photo. There is no purely digital-only path that bypasses the physical document.
EU Digital Identity Wallet and eIDAS 2.0
The EU Digital Identity Wallet is being introduced under the revised eIDAS 2.0 regulation. EU member states are required to make a wallet available to citizens and residents, enabling them to:
- Prove their identity online and in person.
- Share verifiable credentials — such as a driving licence, professional qualification, or university diploma — with public and private services.
- Authenticate themselves to online services across the EU without country-specific logins.
The wallet is tied to existing national identity infrastructure. To obtain an EU Digital Identity Wallet, you first need a valid national identity document (passport or national ID card) issued by your country. The wallet then reads the biometric data from that document's chip via NFC to establish your digital identity credential.
What photo do you need? The ICAO biometric photo required for the underlying physical document — exactly the same as for a standard passport or national ID card application.
How Your Photo Becomes a Chip-Stored Biometric
When you apply for a biometric passport or national ID card, the authority uses your submitted ICAO photograph to:
- Print the visual photo on the data page of the physical document.
- Generate a facial biometric template — a mathematical representation of your facial features extracted from the photo using ICAO-compliant face detection algorithms.
- Store the template on the contactless chip embedded in the document, following ICAO Doc 9303 standards for Machine Readable Travel Documents (MRTDs).
At border control or when onboarding to an eID app, the chip is read via NFC. The reader compares the stored biometric template with a live biometric capture (a camera scan of your face or a live selfie in an app) to confirm that the document holder is the rightful owner.
The quality of the original submitted photo directly affects the quality of the stored biometric template. A low-quality photo with poor lighting, shadow, or incorrect head positioning can produce a weaker template that may fail automated facial recognition checks at e-gates.
Photo for the Card vs. Biometric Template: What's the Difference?
There is an important distinction between:
The printed photo on the card
This is the visual photograph that appears on the front of your passport or ID card. It is checked visually by border officials and airline staff to confirm you match the document. Quality requirements: ICAO 35×45mm, correct size, white background, full face visible, printed at sufficient resolution (typically 600 dpi minimum for the printing process).
The biometric template on the chip
This is a mathematical facial feature vector stored on the NFC chip inside the document, derived from the submitted photo by the issuing authority's software. It is used for automated facial comparison at e-gates, eID app onboarding, and digital identity wallet authentication. The quality of this template depends entirely on the quality of the submitted photo.
Both are derived from the same submitted ICAO photograph, making the quality of the original photo doubly important in the digital identity era.
Digital ID Systems: Photo Requirements and Status
| System | Country | Photo needed | Status |
|---|---|---|---|
| EU Digital Identity Wallet (eIDAS 2.0) | All EU member states | ICAO standard for underlying physical ID document | Rollout in progress (eIDAS 2.0 implementation) |
| German eID (Personalausweis) | Germany | 35×45mm ICAO, white background, for Personalausweis application | Live — eID chip on all Personalausweis since 2010 |
| ID Austria (Austrian eID) | Austria | 35×45mm ICAO, white background, for underlying Personalausweis/Reisepass | Live — successor to Handy-Signatur |
| Swiss eID | Switzerland | 35×45mm ICAO, white background, for underlying Swiss passport/ID card | In development (E-ID-Gesetz 2023) |
| UK Digital Driving Licence | United Kingdom | DVLA-format photo for physical driving licence | In pilot phases (check DVLA for status) |
Digital identity programmes are actively evolving. Always verify the current status and requirements with the official authority in your country.
Country-Specific Notes
Germany — Personalausweis with eID
The German Personalausweis has included an eID chip since 2010. The chip enables online authentication via the AusweisApp2 software. To apply for a Personalausweis, you need a 35×45mm ICAO biometric photo with a plain white background. The eID function is activated by setting a 6-digit PIN at the Bürgeramt. The German eID chip can be used to onboard to the EU Digital Identity Wallet once it is available in Germany.
Austria — ID Austria (successor to Handy-Signatur)
ID Austria is the Austrian eID system that replaced the Handy-Signatur. It links to your Austrian Personalausweis or Reisepass. You activate ID Austria via an in-person identity verification or online via the FinanzOnline system. The underlying physical document requires the standard 35×45mm ICAO biometric photo. Visit the Austrian Federal Chancellery (oesterreich.gv.at) for the current ID Austria activation process.
Switzerland — Swiss eID (in development)
Following the 2023 vote approving the new E-ID-Gesetz, Switzerland is developing a state-issued eID. The Swiss eID will be linked to the Swiss passport or identity card. No separate photo is required for the eID itself — the photo submitted for the physical document is used. The Federal Office of Justice (bj.admin.ch) publishes the current development status.
United Kingdom — Digital driving licence (in pilot)
The UK is developing a digital driving licence as part of its broader digital identity programme governed by the Digital Identity and Attributes Trust Framework. The digital licence uses biometric data from the physical DVLA driving licence. Photo requirements for the physical licence differ from the ICAO passport standard. Check the DVLA and the UK Government's digital identity pages for the current pilot status.
Frequently Asked Questions
Do I still need a physical passport photo for a digital ID wallet?
Yes. The EU Digital Identity Wallet and national eID apps are linked to a physical identity document — typically a passport or national ID card — that must first be issued through the standard process, which requires a biometric ICAO passport photo. The digital wallet then uses the biometric data already stored on the physical document's chip. You cannot obtain an EU Digital Identity Wallet without first obtaining the underlying physical identity document.
What is the EU Digital Identity Wallet?
The EU Digital Identity Wallet is a digital application that EU citizens and residents will be able to use to prove their identity, share credentials (such as a driving licence or university diploma), and authenticate themselves to public and private services online. It is being introduced under the eIDAS 2.0 regulation, with member states required to make a wallet available to citizens by the eIDAS 2.0 implementation deadline.
What photo do I need for the German eID (Personalausweis)?
The German Personalausweis (national ID card with eID function) requires the same ICAO biometric photo as the German passport: 35×45mm, plain white background, neutral expression, no glasses, taken within 6 months of the application date. You apply in person at your local Bürgeramt and bring a printed biometric photo.
How does the Austrian ID Austria eID work?
ID Austria is Austria's electronic identity system, replacing the Handy-Signatur. It is linked to the Austrian Personalausweis (national ID card) or Reisepass. To obtain ID Austria, you need a valid Austrian identity document with a biometric chip. The ID Austria app on your smartphone then uses the chip via NFC to establish your digital identity. The photo required is the standard ICAO biometric photo for the underlying physical document.
What is the status of the Swiss eID?
Switzerland voted in favour of a new federal eID law (E-ID-Gesetz) in 2023, following the rejection of an earlier proposal in 2021. The Swiss e-ID is being developed as a state-issued digital identity credential. As of 2025/2026, implementation is ongoing. The photo required for the underlying Swiss passport or identity card is the standard 35×45mm ICAO biometric photo.
What photo do I need for the UK digital driving licence?
The UK is developing a digital driving licence as part of its digital identity programme. As of 2025/2026, the digital driving licence is in pilot phases. The underlying physical driving licence photo is captured separately during the driving licence application process — it is not a standard ICAO 35×45mm photo but a dedicated DVLA-format photo. The digital version uses the biometric data from the physical licence.
Digital identity programmes are actively evolving across Europe. Information in this guide reflects publicly available information as of May 2026. Always verify the current status and requirements with the official authority in your country — eu-LISA, Bundesdruckerei, Austrian Federal Chancellery, Swiss Federal Office of Justice, or the UK Government digital identity pages.
