Definitions

• the invention relates to a method for transmitting printed information with protection against misuse.
• the invention further relates to an information carrier which is protected against misuse.
• An example of the transmission of printed information is the announcement of price information by a price label on a product, for example in a supermarket.
• One possibility of misuse is to peel off a price label from one product and stick it on another product whose price label has also been removed beforehand or is pasted over.
• This abuse is aggravated by the fact that the price labels are provided with predetermined breaking points, so that the price labels can only be removed in two or three parts.
• the abuse succeeds, however, if enough time is available to assemble the label stuck on the other product and sufficient care is taken.
• the use of more complex security systems is opposed by the labeling process, which is designed as a mass process.
• PIN numbers for credit cards, access authorizations or the like.
• PIN numbers are colorlessly embossed in a closed form in the form of a carbon copy, so that the PIN number can only be read on the inside carbon paper covered cover page.
• the recipient of the PIN number can therefore be sure that no third party has taken note of the printed PIN number if the set of forms is locked intact. If an opening has taken place, the PIN number can be invalidated immediately and replaced by a new, valid PIN number. For this security, the great effort is carried out in practice with the carbonless form sets.
• the invention has for its object to enable the transmission of printed information with sufficient protection against misuse in a simple and easy to manufacture.
• a method of the type mentioned at the outset is characterized in that the information is provided by means of a flat carrier fastened to a base by an adhesive, which is split due to a lower cohesive force than the adhesive force of the adhesive when removed.
• the attempt to remove the carrier from the excellent product leads to the splitting of the carrier according to the invention, so that the surface provided with the price information now has a Carrier residue is connected, which has no adhesive effect. It is therefore not possible to stick it on another product.
• a particularly advantageous embodiment of the inventive concept is when the carrier residue connected to the adhesive can be detached from the substrate, in particular in such a way that the substrate is not damaged in any way. If the product is purchased legally, the carrier residue can be removed without any problems. For this it is necessary to set the adhesive force between the adhesive and the substrate exactly. On the one hand, this must be less than the force required to split the support, on the other hand, it must not be so great that the adhesive affects the surface when removing the rest of the support.
• the method according to the invention can advantageously also be carried out when the printed information is covered by the carrier and the carrier and the adhesive are at least translucent in such a way that the information can be read after the carrier has been split.
• the information for example a PIN number
• the covering effect must be effected on the top of the carrier, for example by coloring the surface, sticking on a non-translucent material, etc.
• the splitting of the carrier when peeling off and the translucent design of the carrier and the adhesive make the information, for example the PIN number, legible. It is not possible to restore the cover to conceal the (unauthorized) knowledge of the PIN number, since the split carrier material has no adhesive effect and, because of the irregular splitting, cannot be put together again with normal effort so that the fact of the split remains unnoticed ,
• Fissile adhesive systems are known in principle and are used, for example, for temporarily fixing a paper tape wound on a roll on the winding underneath, in order to avoid unwanted winding up of the paper tape and yet to be able to easily detach the end from the roll if required. In the completely different field of information transmission addressed here, the suitability of the use of fissile systems has not become known.
• the flat carrier 2 has a lower cohesive force than the adhesive force of the adhesive with which the carrier 2 is glued to the base.
• the carrier 2 When attempting to pull off the carrier 2 from the base, the carrier 2 thus splits, as a result of which the opaque surface 3 is pulled off with part of the carrier 2.
• the carrier 2 and the adhesive located underneath are transparent or at least translucent, so that when the carrier 2 is split, the information 1 covered by the non-split carrier 2 with the surface layer 3 is now visible.
