# Article 12 - Record Keeping  (ART12)

High-risk AI systems shall be designed and developed with capabilities enabling the automatic recording of events (‘logs’) while the high-risk AI systems is operating ([12.01](/ec-aia-compliance/article-12-record-keeping-art12/12.01-logging-capabilities.md)). Those logging capabilities shall conform to recognised standards or common specifications.

The logging capabilities shall ensure a level of traceability of the AI system’s functioning throughout its lifecycle that is appropriate to the intended purpose of the system ([12.02](/ec-aia-compliance/article-12-record-keeping-art12/12.02-logging-traceability.md)).

In particular, logging capabilities shall enable the monitoring of the operation of the high-risk AI system with respect to the occurrence of situations that may result in the AI system presenting a risk within the meaning of Article 65(1) ([12.03](/ec-aia-compliance/article-12-record-keeping-art12/12.03-logging-situations-that-may-cause-ai-risk.md)) or lead to a substantial modification, and facilitate the post-market monitoring referred to in Article 61.

For high-risk AI systems intended to be used for the ‘real-time’ and ‘post’ remote biometric identification of natural persons shall provide, at a minimum ([12.04](/ec-aia-compliance/article-12-record-keeping-art12/12.04-logging-biometric-systems-requirements.md)):

1. Recording of the period of each use of the system (start date and time and end date and time of each use);
2. The reference database against which input data has been checked by the system;
3. The input data for which the search has led to a match;
4. The identification of the natural persons involved in the verification of the results, as referred to in Article 14 (5).

 Below is the list of controls/checks part of Article 12.
