Where it is technically impossible to enter data in the EES Central System or in the event of a failure of the EES Central System, the data referred to in Articles 16 to 20 shall be temporarily stored in the NUI. Where that is not possible, the data shall be temporarily stored locally in an electronic format. In both cases, the data shall be entered in the EES Central System as soon as the technical impossibility or failure has been remedied. The Member States shall take the appropriate measures and deploy the required infrastructure, equipment and resources to ensure that such temporary local storage may be carried out at any time and for any of their border crossing points.

Without prejudice to the obligation to carry out border checks under Regulation (EU) 2016/399, the border authority, in the exceptional situation where it is technically impossible to enter data in both the EES Central System and in the NUI and it is technically impossible to temporarily store the data locally in an electronic format, shall manually store the data referred to in Articles 16 to 20 of this Regulation, with the exception of biometric data, and shall affix an entry or exit stamp in the travel document of the third-country national. That data shall be entered in the EES Central System as soon as technically possible.

Member States shall inform the Commission of the stamping of travel documents in the event of the exceptional situations referred to in the first subparagraph of this paragraph. The Commission shall adopt implementing acts concerning the detailed rules on the information to be provided to the Commission. Those implementing acts shall be adopted in accordance with the examination procedure referred to in Article 68(2).

The EES shall indicate that data referred to in Articles 16 to 20 were entered as a result of a fall-back procedure and that the individual file created pursuant to paragraph 2 of this Article is missing biometric data. The biometric data shall be entered in the EES at the next border crossing.
