Definition: European dactyloscopy (EURODAC)
The Eurodac system enables European Union (EU) countries to help identify asylum applicants and persons who have been apprehended in connection with an irregular crossing of an external border of the Union. By comparing fingerprints, EU countries can determine whether an asylum applicant or a foreign national found illegally present within an EU country has previously claimed asylum in another EU country or whether an asylum applicant entered the Union territory unlawfully.
