Abstract: In an aspect, the present invention provides a document having a first page and a second page connected by a hinge portion. In illustrative embodiments, the document comprises an RF chip module, a first antenna portion formed on the first page, a second antenna portion formed on the second page, and at least one foldable bridge formed on the hinge portion, wherein the at least one foldable bridge electrically connects endings of the first and second antenna portions such that the first and second antenna portions have a first inductance adapted to provide the document with a first resonance frequency in a closed condition of the document in which the first page is placed on the second page, while the first and second antenna portions have a second inductance adapted to provide the document with a second resonance frequency different from the first resonance frequency in an open condition of the document in which the first page is removed from closed condition.

Abstract: A datapage of a security document includes a non-planar end face that is to be connected to a hinge material, thereby providing for increased overall contact surface area between hinge material and the datapage. Consequently, a respective connecting portion including such an interdigitated structure may provide for superior robustness while still ensuring a high degree of integrity of the datapage and a robust mechanical connection to the remainder of the security document.

Abstract: A pre-laminate usable for forming a datapage of a security document, includes layers of different optical appearance, such as a clear window-type portion, which may be obtained on the basis of a substantially even or flat surface. Since the desired optical appearances of different areas of the pre-laminate are established in an early manufacturing stage, any process steps to be applied in a later manufacturing stage upon forming, for instance, an optical window, in a datapage, may be omitted, thereby contributing to reduced overall manufacturing costs and enhanced tamper resistance of the resulting datapage.

Abstract: A pre-form for a security document comprising at least a bottom layer, a central layer and a top layer is presented, wherein the central layer comprises one or more insert inlays disposed between a first corner and a second corner of one side, so as to form a horizontal color-coded pattern, wherein said one or more insert inlays comprise a light guide material that can interact with input light entering through at least one window of the pre-form for a security document and exiting from the one or more inserts, so that the color-coded pattern is modified by the interaction between a predefined input light and the light guide material. Moreover, the methods for producing the pre-form for a security document and for operating it in such a way to assure superior tampering resistance are disclosed.

Abstract: The present invention provides for a prelam body of a smart card, a smart card, a method of forming a prelam body of a smart card, and a method of forming a smart card. In accordance with some embodiments herein, a prelam body comprises a base substrate formed of at least one layer, and at least one overlay sheet layer formed on one side of the base substrate, wherein the at least one overlay sheet layer has a recess formed therein. The recess is at least partially extending through the at least one overlay sheet layer such that an opening of the recess is exposed.
