EU AI Act Compliance for Biometrics

EU AI Act compliance for biometric AI systems, covering prohibited practices, high-risk classification, and real-time identification.

Providers and deployers of remote biometric identification, biometric categorisation and emotion recognition systems face high-risk rules from 2 December 2027 (Annex III, point 1).

Annex III’s “Biometrics” area is limited to points 1(a) to 1(c). Point 1(a) excludes one-to-one verification. Article 5 has prohibited some biometric practices since 2 February 2025, with higher fines (Article 99(3)). For high-risk obligations, fines reach EUR 15 million or, for an undertaking, 3% of worldwide annual turnover, whichever is higher (Article 99(4)). Next step: map each system to point 1(a), 1(b) or 1(c), and check Article 5 first.

What the Act covers under biometrics

Annex III point 1 covers biometrics in so far as its use is permitted under relevant Union or national law. This site’s word “biometrics” maps to the hooks below.

  • Point 1(a): remote biometric identification systems

    A remote biometric identification system identifies natural persons without their active involvement, typically at a distance, by comparing a person’s biometric data with the biometric data in a reference database (Article 3(41)). Annex III lists these systems without separating real-time from post-remote identification (Article 3(42), Article 3(43)).

  • Verification is excluded from point 1(a)

    Point 1(a) does not include AI systems intended to be used for biometric verification the sole purpose of which is to confirm that a specific natural person is the person he or she claims to be. Biometric verification is automated one-to-one verification, including authentication, by comparing biometric data to previously provided biometric data (Article 3(36)). Such a system is high-risk only if another point of Annex III or Annex I covers it.

  • Point 1(b): categorisation by sensitive or protected attributes

    AI systems intended to be used for biometric categorisation, according to sensitive or protected attributes or characteristics based on the inference of those attributes or characteristics. A biometric categorisation system assigns natural persons to specific categories on the basis of their biometric data, unless it is ancillary to another commercial service and strictly necessary for objective technical reasons (Article 3(40)). Article 5(1), point (g) prohibits some categorisation (see below).

  • Point 1(c): emotion recognition

    AI systems intended to be used for emotion recognition. An emotion recognition system is an AI system for the purpose of identifying or inferring emotions or intentions of natural persons on the basis of their biometric data (Article 3(39)). Article 5(1), point (f) prohibits inferring emotions in the workplace and in education institutions, except for medical or safety reasons (see below).

  • Points 6 and 7: other public-authority uses

    Annex III point 7(d) covers AI systems used by or on behalf of competent public authorities, or by Union institutions, bodies, offices or agencies, in the context of migration, asylum or border control management, for the purpose of detecting, recognising or identifying natural persons, with the exception of the verification of travel documents. Point 6 lists law-enforcement uses; see the law enforcement overview. Registration of systems under points 1, 6 and 7 in these areas is in a secure non-public section of the EU database (Article 49(4)).

  • Real-time, post-remote and law enforcement

    A ‘real-time’ remote biometric identification system is one where capturing biometric data, comparison and identification all occur without a significant delay, including limited short delays to avoid circumvention (Article 3(42)). A post-remote system is any other remote biometric identification system (Article 3(43)). ‘Law enforcement’ means activities carried out by law enforcement authorities or on their behalf for the prevention, investigation, detection or prosecution of criminal offences or the execution of criminal penalties, including safeguarding against and preventing threats to public security (Article 3(46)). A law enforcement authority is a public authority competent for those tasks, or any other body or entity entrusted by Member State law to exercise public authority and public powers for them (Article 3(45)). A ‘publicly accessible space’ is any publicly or privately owned physical place accessible to an undetermined number of natural persons, regardless of whether certain conditions for access may apply (Article 3(44)).

Article 5 prohibitions that concern biometric systems, for example

Points (e) to (h) of Article 5(1) have applied since 2 February 2025 (Article 113, point (a)). Fines go up to EUR 35 million or, for an undertaking, up to 7% of total worldwide annual turnover, whichever is higher (Article 99(3)).

  • Untargeted scraping to build face databases (point (e))

    AI systems that create or expand facial recognition databases through the untargeted scraping of facial images from the internet or CCTV footage. The prohibition covers placing on the market, putting into service for this specific purpose, and use. The text names no consent test and no named data set.

  • Emotion inference at work and in education (point (f))

    AI systems to infer emotions of a natural person in the areas of workplace and education institutions, except where the use of the system is intended to be put in place or into the market for medical or safety reasons. Emotion recognition systems are listed in Annex III point 1(c), which does not limit them to an area.

  • Biometric categorisation of sensitive traits (point (g))

    Biometric categorisation systems that categorise individually natural persons based on their biometric data to deduce or infer their race, political opinions, trade union membership, religious or philosophical beliefs, sex life or sexual orientation. The prohibition does not cover any labelling or filtering of lawfully acquired biometric datasets, such as images, based on biometric data, or categorizing of biometric data in the area of law enforcement.

  • Real-time remote identification for law enforcement (point (h))

    The use of ‘real-time’ remote biometric identification systems in publicly accessible spaces for the purposes of law enforcement is prohibited unless and in so far as strictly necessary for one of three objectives. The first is the targeted search for specific victims of abduction, trafficking in human beings or sexual exploitation, and for missing persons. The second is the prevention of a specific, substantial and imminent threat to life or physical safety, or a genuine and present or genuine and foreseeable threat of a terrorist attack. The third is the localisation or identification of a person suspected of a criminal offence listed in Annex II and punishable by a custodial sentence or detention order of a maximum of at least four years. Use may only confirm the identity of the specifically targeted individual (Article 5(2)). Each use needs a prior authorisation by a judicial authority or an independent administrative authority whose decision is binding. In a duly justified situation of urgency, use may start without authorisation, provided it is requested without undue delay and at the latest within 24 hours. If it is rejected, the use stops with immediate effect and the data and results are deleted (Article 5(3)). Authorisation also requires a completed fundamental rights impact assessment and registration of the system in the EU database; in duly justified urgency, registration may follow without undue delay (Article 5(2)). Each use is notified to the market surveillance authority and the national data protection authority (Article 5(4)). Those authorities send annual reports to the Commission, which publishes annual reports (Article 5(6), Article 5(7)). A Member State may decide whether to provide for such authorisation (Article 5(5)). Point (h) concerns use for the purposes of law enforcement; it is without prejudice to Article 9 of Regulation (EU) 2016/679 for other purposes.

Provider and deployer

  • Providers

    A provider develops a system, or has it developed, and places it on the market or puts it into service under its own name or trademark (Article 3(3)). A provider must ensure that its high-risk system complies with the requirements of Section 2, which includes Articles 9 to 15, have a quality management system under Article 17, and ensure the conformity assessment under Article 43 before placing the system on the market or putting it into service (Article 16, points (a), (c) and (f)).

  • Deployers

    A deployer is a natural or legal person, public authority, agency or other body using an AI system under its authority (Article 3(4)). Deployers take appropriate technical and organisational measures to use the system in accordance with the instructions for use, assign human oversight to natural persons with the necessary competence, training and authority, and keep the logs under their control (Article 26, paragraphs 1, 2 and 6). Deployers that are public authorities register their use in the EU database (Article 26(8), Article 49(3)). Deployers that are bodies governed by public law, or private entities providing public services, perform a fundamental rights impact assessment before deploying a system referred to in Article 6(2) (Article 27(1)).

  • Deployers of post-remote biometric identification

    In an investigation for the targeted search of a person suspected or convicted of a criminal offence, the deployer of a post-remote biometric identification system must request an authorisation, ex ante or without undue delay and no later than 48 hours, by a judicial authority or an administrative authority whose decision is binding and subject to judicial review. The exception is use for the initial identification of a potential suspect based on objective and verifiable facts directly linked to the offence. No decision that produces an adverse legal effect on a person may be taken by the law enforcement authorities based solely on the output of such a system. Regardless of the purpose or deployer, each use of such systems is documented in the relevant police file and made available to the market surveillance authority and the national data protection authority upon request, excluding sensitive operational data related to law enforcement. Deployers must submit annual reports on their use of post-remote biometric identification systems to those authorities; the reports may be aggregated (Article 26(10)).

Key dates

2 February 2025

Article 5(1), points (e) to (h): the prohibited biometric practices apply (Article 113, point (a)). Chapter XII on penalties, including Article 99, applies from 2 August 2025 (Article 113, point (b)).

2 August 2026

Article 50(3): deployers of emotion recognition or biometric categorisation systems inform the exposed persons. Article 50 is not named in points (a) to (d) of Article 113, so the general date of that Article applies.

2 December 2027

The requirements for systems under Annex III point 1 apply, including Articles 9 to 15, 17, 26 and 27 (Article 113, point (c)(i)). Articles 43 and 49 are in Section 5 of Chapter III; Article 113 gives no separate date for that Section, which is a question for counsel.

2 August 2030

A system placed on the market or put into service before 2 December 2027 is covered only if its design changes significantly afterwards. Providers and deployers of high-risk systems intended for use by public authorities take the necessary steps to comply by this date (Article 111(2)). This rule does not cover the systems referred to in Article 111(1).

31 December 2030

Components of the large-scale IT systems listed in Annex X that were placed on the market or put into service before 2 August 2027 are brought into compliance by this date (Article 111(1)).

Fines

Breaches of the Article 5 prohibitions can be fined up to EUR 35 million or, for an undertaking, up to 7% of its total worldwide annual turnover for the preceding financial year, whichever is higher (Article 99(3)). Breaches of the provider obligations in Article 16 and the deployer obligations in Article 26 can be fined up to EUR 15 million or, for an undertaking, up to 3%, whichever is higher; the same tier covers the transparency obligations in Article 50 (Article 99(4), points (a), (e) and (g)). For SMEs, including start-ups, each fine is up to whichever of the two is lower (Article 99(6)). For small mid-cap enterprises (Article 3(14b)) the same applies to the fines in Article 99(4) and Article 99(5), but not to those in Article 99(3) (Article 99(6a)). Each Member State lays down rules on to what extent administrative fines may be imposed on public authorities and bodies established in that Member State (Article 99(8)). Article 99(3) to (5) names no tier for Article 27 or Article 49.

The rules for biometric systems, article by article

  • Art. 5(1)(e)–(h)
    Prohibitions: check first

    Check whether the system falls under points (e) to (h) of Article 5(1) before applying the high-risk rules. See the prohibitions above.

  • Art. 9
    Risk management system

    A provider duty. It includes consideration of persons under 18 and other vulnerable groups (Article 9(9)). The Act names no biometric risk value or method.

  • Art. 10, 4a
    Data governance and special categories of data

    Quality criteria for training, validation and testing data (Article 10). Providers may exceptionally process special categories of personal data for bias detection and correction under six conditions (Article 4a(1)).

  • Art. 12(3)
    Record-keeping: minimum log content

    For point 1(a) systems, the logs record the period of each use, the reference database, the input data that led to a match, and the persons who verified the result (Article 12(3)).

  • Art. 13
    Transparency and instructions for use

    The provider supplies instructions for use with at least the items in Article 13(3). Article 13 sets no rule on signs or notices for people captured by a system.

  • Art. 14(5)
    Human oversight: two-person check

    For point 1(a) systems, no action or decision on an identification before separate verification and confirmation by at least two natural persons with the necessary competence, training and authority (Article 14(5)). Exemption for law enforcement, migration, border control and asylum where law considers it disproportionate.

  • Art. 15, 17
    Accuracy, robustness, cybersecurity and quality management

    Provider duties (Article 15, Article 17). The Act names no accuracy value, error-rate metric or test method for biometrics. The provider declares the levels and metrics of accuracy in the instructions for use (Article 15(3)).

  • Art. 26–27
    Deployer duties and fundamental rights impact assessment

    Use in accordance with the instructions, human oversight, logs (Article 26). Deployers of high-risk systems under Annex III that make or assist in decisions related to natural persons inform those persons (Article 26(11)). Post-remote identification in criminal investigations: authorisation and reporting (Article 26(10)). Fundamental rights impact assessment for the deployers named in Article 27(1).

  • Art. 43(1)
    Conformity assessment route for point 1

    Where the provider has applied harmonised standards (Article 40) or, where applicable, common specifications (Article 41), it opts for internal control under Annex VI or an assessment with a notified body under Annex VII. Annex VII applies where such standards do not exist and common specifications are not available, where the provider has not applied or has applied only part of the standard, where it has not applied existing common specifications, or where a standard was published with a restriction. For systems put into service by law enforcement, immigration or asylum authorities or by Union institutions, the market surveillance authority acts as notified body (Article 43(1)).

  • Art. 49
    Registration in the EU database

    Providers register themselves and their system before placing it on the market or putting it into service (Article 49(1)). Deployers that are public authorities register their use (Article 49(3)). For systems under points 1, 6 and 7 in the areas of law enforcement, migration, asylum and border control management, registration is in a secure non-public section with limited information (Article 49(4)).

  • Art. 50(3)
    Information duty for emotion recognition and biometric categorisation

    Deployers of an emotion recognition system or a biometric categorisation system inform the natural persons exposed to it of the operation of the system, and process the personal data in accordance with data protection law. The obligation does not apply to systems permitted by law to detect, prevent or investigate criminal offences, subject to appropriate safeguards and in accordance with Union law (Article 50(3)). Remote biometric identification is not named in this paragraph.

Questions about biometrics and the AI Act

Is one-to-one face or fingerprint verification high-risk?

Not through Annex III point 1(a), which does not include AI systems intended to be used for biometric verification the sole purpose of which is to confirm that a specific natural person is the person he or she claims to be. Such a system is high-risk only if another point of Annex III or Annex I covers it (Article 6).

Is real-time facial recognition in a shop prohibited?

Article 5(1), point (h) prohibits the use of ‘real-time’ remote biometric identification systems in publicly accessible spaces for the purposes of law enforcement, unless strictly necessary for one of three objectives. It does not name use for other purposes. Remote biometric identification systems are listed in Annex III point 1(a), and Article 9 of the GDPR remains applicable to biometric data processing for purposes other than law enforcement.

Does the Act ban emotion recognition?

Article 5(1), point (f) prohibits AI systems that infer emotions of a natural person in the areas of workplace and education institutions, except where the use is intended for medical or safety reasons. Emotion recognition systems are listed in Annex III point 1(c), and deployers inform the exposed persons (Article 50(3)).

Is biometric categorisation banned?

Only categorisation that deduces or infers race, political opinions, trade union membership, religious or philosophical beliefs, sex life or sexual orientation (Article 5(1), point (g)), with the carve-outs in that point. Other biometric categorisation according to sensitive or protected attributes can fall under Annex III point 1(b).

Which biometric-specific rules does the Act add to Articles 9 to 15?

Article 12(3) sets minimum log content and Article 14(5) the two-person check, both for Annex III point 1(a) systems. Article 26(10) governs post-remote identification in criminal investigations. Article 43(1) sets the conformity assessment route for point 1 systems. Article 49(4) sets non-public registration for points 1, 6 and 7 in the named areas. Article 50(3) is the information duty for emotion recognition and biometric categorisation.
