Definition
mDowód (from "mobilny dowód osobisty" -- mobile personal identity document) is Poland's digital identity credential that provides a mobile equivalent of the physical dowód osobisty (national ID card). Integrated into the mObywatel government app, mDowód displays the citizen's identity information including name, date of birth, PESEL number (national identification number), photograph, and ID card details directly on their smartphone. With legal recognition for numerous domestic use cases and over 15 million users, mDowód represents one of the most successful mobile identity deployments in Europe and serves as the foundation for Poland's EUDI Wallet implementation.
Technical Architecture and Security
mDowód operates as a digitally signed credential within the mObywatel application. The credential is issued by the Polish Ministry of Digital Affairs and cryptographically bound to the user's verified identity. Activation requires the user to authenticate using their Profil Zaufany (trusted profile) or bank identity -- both of which provide strong identity verification against government databases.
The credential includes a dynamic QR code that can be scanned by verifiers (such as police officers using dedicated verification equipment) to confirm the document's authenticity and check its current validity status. This QR-based verification mechanism provides a level of anti-forgery protection that supplements the visual display of identity information on the screen.
Security measures include device binding (the credential is tied to the specific smartphone), biometric or PIN protection through the mObywatel app, and periodic re-verification requirements. If the physical ID card is reported lost or stolen, the corresponding mDowód is automatically invalidated. Similarly, if the mObywatel app detects device compromise indicators, the credential display can be blocked.
The current implementation stores credential data locally on the device, aligning with the local-first storage approach that will carry forward into the EUDI Wallet version. However, the cryptographic mechanisms will need significant upgrades for eIDAS 2.0 compliance, including hardware-backed key attestation and standardized selective disclosure.
Legal Recognition and Accepted Use Cases
Polish law grants mDowód legal recognition for a growing list of domestic use cases. Police officers can accept mDowód during routine identity checks, and a 2019 amendment to the identity documents law formalized this acceptance. Citizens regularly use mDowód for age verification (purchasing alcohol, entering restricted venues), postal service identity confirmation (collecting registered mail), and accessing government digital services.
The document has also gained acceptance in practical commercial scenarios. Many Polish banks accept mDowód for in-branch identity verification, and telecommunications companies use it for SIM card registration. The widespread practical acceptance has been a key driver of adoption, creating a virtuous cycle where more acceptance points drive more users, and more users encourage more organizations to accept the credential.
However, mDowód currently has limitations. It cannot be used as a travel document at international borders, as it lacks the ICAO-compliant chip reading that physical ID cards provide. It is also not universally accepted by all private sector entities, as acceptance remains voluntary outside of specifically mandated scenarios. The transition to EUDI Wallet compliance under eIDAS 2.0 aims to address these gaps through mandatory acceptance requirements and cross-border interoperability standards.
Path to EUDI Wallet Compliance
Poland's strategy for EUDI Wallet implementation builds directly on the mDowód/mObywatel infrastructure. The upcoming mObywatel 3.0 will transform mDowód from a proprietary Polish credential into an eIDAS 2.0-compliant Person Identification Data (PID) credential that meets LoA High requirements and can be verified by organizations across all EU Member States.
Key technical upgrades for EUDI compliance include: adopting standardized credential formats (mDoc and SD-JWT), implementing selective disclosure so users can share only specific attributes rather than the full identity document, integrating hardware-backed secure elements for key attestation, and supporting the OpenID4VP and OpenID4VCI protocols for interoperable credential presentation and issuance.
The transition is designed to be smooth for existing mObywatel users. Citizens will receive an app update that introduces the new EUDI Wallet capabilities while maintaining the familiar interface they already use daily. Their existing mDowód will be upgraded in-place to the new credential format, potentially requiring a one-time re-verification against their physical eID card to establish LoA High assurance. Poland's existing user base of over 15 million gives it one of the strongest starting positions for EUDI Wallet adoption in the EU.
