With a view to facilitating the procedures for the identification and the issuance of travel documents for return purposes of illegally staying third-country nationals or stateless persons, a scanned colour copy of an identity or travel document should be recorded in Eurodac, where available, along with an indication of its authenticity. If such an identity or travel document is not available, only one other available document identifying the third-country national or stateless person should be recorded in Eurodac along with an indication of its authenticity. In order to facilitate the procedures for the identification and the issuance of travel documents for return purposes of illegally staying third-country nationals or stateless persons, and in order not to populate the system with counterfeit documents, only documents validated as authentic or the authenticity of which cannot be established due to the absence of security features should be kept in the system.
