Razlog za to je, da mora SIS, kakor je določeno v členu 92 Schengenske konvencije, omogočiti organom, ki jih določijo države članice, dostop do razpisov ukrepov za osebe in premoženje s postopkom avtomatskega preiskovanja za namene mejnih kontrol in drugih policijskih in carinskih kontrol, ki se izvajajo v notranjosti države v skladu z nacionalno zakonodajo in za namene izdaje vizumov, dovoljenj za prebivanje in izvajanja zakonodaje o tujcih v smislu uporabe določb Schengenskega pravnega reda o gibanju oseb.
The reason for this is that, as set out in Article 92 of the Schengen Convention, the SIS is to enable the authorities designated by the Member States, by means of an automated search procedure, to have access to alerts on persons and property for the purposes of border checks and other police and customs checks carried out within the country in accordance with national law, as well as for the purposes of issuing visas, residence permits and the administration of legislation on aliens in the context of the application of the provisions of the Schengen acquis relating to the movement of persons.
