It is appropriate to defer the collection and transmission of biometric data of third-country nationals or stateless persons registered as a beneficiary of temporary protection to three years after the entry into application of the other provisions of this Regulation, in order to ensure sufficient time for the Commission to assess the functioning and the operational efficiency of any IT system used to exchange the data of beneficiaries of temporary protection and the expected impact of such collection and transmission in the event that Directive 2001/55/ECTemporary Protection Directive is activated.
