The purpose of this data processing operation is to register and to control all the visitors (non EU Delegation staff) who access the premises of an EU Delegation. Description of the processing operation. Before allowing any visitor (including a family member of Delegation staff) to enter the Delegation premises the receptionist/ security guard* will check with the person receiving the visit and, if the visit is confirmed. The receptionist/security guard will deliver a numbered "Visitor" access card upon showing a valid picture ID card. Unless an equivalent procedure is in place, the receptionist/security guard will retain the ID card until the "Visitor" card is returned. The receptionist/ security guard records personal data from the visitor and the entry and exit times in the visitors' registry/logbook.
