Problems solved by technology

Locally different adhesive forces lead to the fact that scratch-off labels can be seen to be damaged in the event of unauthorized removal and the information is only partially disclosed
While in the production of such scratch-off labels, the production process may be subject to changes due to changing production parameters, and these changes may cause the desired effect not to be fully achieved

Embodiment Construction

[0019] figure 1 A device 1 is shown consisting of an object 2 and a scratch area 3 with a small surface, wherein the object 2 is a value card, for example a prepaid telephone card (prepaid card), on which information 4 is applied in a protected manner. Similarly, any other desired value document or any value object can be used as the object. In top view, the device 1 comprises a scratch area 3 applied to the value card 2 as an opaque cover layer on the layer structure 8 , 9 printed on the value card 2 . The opaque covering of the scratch-off area 3 of the value card 2 can be easily scratched off with a fingernail or another suitable object, revealing the information 4 arranged thereunder. figure 1 The layer 8 , 9 arranged below the scraping area 3 is shown schematically (in dashed lines) in . In the top view of unused cards, they are completely hidden by scratch area 3.

[0020] image 3 A cross-section of the layer structure of the device 1 is shown. To produce the value...

Abstract

According to the invention, in order to secure an information item (4) hidden on an object (2) by a scratch field (3), intermediate layers between the information item (4) and the object (2) are provided with transversal recesses (10, 11) which form the spatial structure thereof. Said recesses (10, 11) are arrangeable on at least one layer (9) in the information item (4) area and / or on at least two layers in an area which surrounds said information item (4) and to which the information item (4) is not applied. In the first case, the parts of the information item (4) are printed on several layers (8, 9) and are disclosable by removing a layer. In the second case, a scalpel is guided to the lower layers devoid of information (4) if they are improperly lifted.

Description

technical field [0001] The invention relates to a device having applied thereon protected information, such as barcodes, identification tokens, PIN codes, etc., and an object for concealing the protected information. The invention also relates to a method of producing such a device. Background technique [0002] It is known to hide passwords, PIN codes or other secret information on value documents, such as bank or credit cards, prepaid telephone cards, chip cards, etc., by means of a removable opaque cover layer, the cover layer often Shown as covered adhesives or scratch-off labels. Typically, the authorized owner of a document of value removes the covering by scratching it off, thereby finding out the information intended for him. [0003] However, it should be possible that unauthorized persons may inadvertently attempt to falsify such that authorized persons may obtain falsified messages. Similarly, it is important that a person holding a document of value with an un...
