The Convention Implementing the Schengen Agreement and the national implementing legislation in the European Union Member States requires business accommodations to see to it that foreign guests complete and sign registration forms and confirm their identity by producing a valid identity document. These registration forms must be made available to law enforcement agencies upon request if necessary for the fulfillment of their duties. Business accommodations must ensure that registration forms are safely and securely stored and cannot be accessed by unauthorized persons. They must be destroyed after a certain time.
