Problems solved by technology

[0008] Sometimes, however, it is difficult for an untrained observer to clearly verify that the observed animations do correspond to those specified by the real credentials, as such animations are often in precise configurations that may be difficult for the operator to determine to be able to observe
Therefore, there may still be doubts about the authenticity of the credentials

Embodiment Construction

[0037] Figure 1 to Figure 3 A security credential of a first embodiment of the invention is shown. This security credential is indicated generally by reference numeral 10 .

[0038] In a first embodiment, the voucher 10 is a banknote. In a variant, the document 10 may be a passport, a driver's license or any other document that may need to be secured.

[0039] Voucher 10 includes a substrate 12 made, for example, of a material consisting essentially of plastic, paper, or a mixture of plastic and paper, although the invention is not limited to any particular material. Where appropriate, the material of the substrate may also be a multilayer structure comprising a plurality of layers laminated together.

[0040] The substrate 12 also includes a translucent region 14, which is preferably transparent, and which is referred to as a "window" in the following description. This region 14 is preferably surrounded by an opaque region 16 .

[0041] The presence of such a window 14 ...

Abstract

The invention relates to a document (10) which includes a substrate (12) and a security element (20) including first (22A) and second (22B) patterns supported by the substrate (12), the substrate (12) also including a translucent or transparent area (14), with the first and second patterns (22A, 22B) at least partially extending therein. The first and second patterns (22A, 22B) are suitable for producing, inside the transparent area (14), at least first and second colours respectively when observing the document (10) by reflection and for switching said first and second colours when observing the document (10) being sent.

Description

technical field [0001] The present invention relates to the technical field of secure elements for important documents such as security documents. Background technique [0002] The term "security document" is meant in the present invention to cover any document used to communicate large sums of money, such as banknotes, checks and bank cards. [0003] The term "like document" refers to any document issued by the state authority to verify personal identity and driving rights, such as ID card, passport, driver's license, etc. The term also covers any credentials used to identify valuables, such as labels on luxury clothing. In addition, the term also covers any document used to identify tax payments, such as tax stickers. [0004] Currently, there is a great demand for important credentials that include secure elements that are easily identifiable to the naked eye and difficult to replicate. Such a secure element is also referred to as a "level one" secure element. [0005...
