Zusammenfassung:A data carrier having at least one optically variable element, at least one surface element, and at least one security element comprising at least part of the at least one optically variable element and at least part of the at least one surface element. The at least one surface element is configured to guide impinging electromagnetic radiation towards the at least one optically variable element. The data carrier is configured such, that electromagnetic radiation is impinging on the at least one surface element under at least a first arrival angle when the data carrier is seen under a first observation angle, and such, that electromagnetic radiation is impinging on the at least one surface element under at least a second arrival angle being different from the first arrival angle when the data carrier is seen under a second observation angle being different from the first observation angle. The at least one optically variable element is configured to reflect at least a first reflection spectrum upon impingement of the electromagnetic radiation being impinging on the at least one surface element under the first arrival angle, whereby the at least one security element appears according to at least a first appearance, and is further configured to reflect at least a second reflection spectrum upon impingement of the electromagnetic radiation being impinging on the at least one surface element under the second arrival angle, whereby the at least one security element appears according to at least a second appearance being different from the first appearance.
