It is necessary to designate and keep a list of the operating units of Europol that are authorised to request comparisons with Eurodac data through the Europol Access Point. Such units, including units dealing with trafficking in human beings, sexual abuse and sexual exploitation, in particular where victims are minors, should be authorised to request comparisons with Eurodac data through the Europol Access Point in order to support and strengthen action by Member States in preventing, detecting or investigating terrorist offences or other serious criminal offences falling within Europol’s mandate.
