The electronic terminals or kiosks are located near the customs area of the airport or port of exit from the territory of the European Union and ensure:
a) The reading of the identification document and the boarding pass of the traveler;
b) The selection of invoices that the traveler intends to submit for certification;
c) The indication that the conditions of the exemption have been confirmed, certifying the export (the certification may be total or partial, depending on all or only some of the invoices being certified) by means of a green light.
d) If the conditions for verification of the exemption are not met, the kiosk will issue a warning (“red light”). In this case, the traveler will have to go to the customs services office for certification.
