TECHNICAL FIELD [0001] The present invention relates to a method of manufacturing a security tape for a plastic card,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a method for manufacturing a plastic card, and more particularly, to a method for manufacturing a plastic card, In order to prevent the information on the card from being used in advance, a plastic card which can be used to publicly display the fact of use of the sealed tape when the sealed password is used after sealing the unique password of the plastic card The present invention relates to a method of manufacturing a security tape for a security tape.

Today, many plastic cards are widely used. As a result of the development of information technology, the plastic card has been firmly established as one of the newly introduced payment instruments in accordance with the change of the era in which the credit transaction is mainly focused on the conventional cash transaction.

Plastic cards do not need to carry money directly, and sometimes they earn points and get a proper discount rate. Therefore, the use of plastic cards continues to expand.

Today, plastic cards can go beyond the scope of conventional plastic cards that are used as a simple financial transaction or transaction payment tool, they can be used as a kind of voucher, It is also used as a calling card, which is a calling card developed to be used for various purposes.

Such a plastic card may be classified into a general financial card and a functional card to which a specific function is added. In the plastic card, a main body of the card is formed by laminating a plurality of thin plastic sheets, And a magnetic stripe or an IC chip or the like is attached to the back of the card, and then a printing surface is formed on the front and back surfaces of the card. At this time, in order to prevent illegal use of the inside information of the plastic card, a unique identification code number (CVC: Card Validation Code) of the card is written on the back side (back side) of the plastic card, (Hereinafter, referred to as " security information " including the unique identification code number (CVC) of the card, pin number, and other security-related information in the present invention) Is used.

However, the sealing tape used today is such that when someone uses the tape by tearing it off, the tape itself may be damaged or the plastic card may have adhesive on the surface thereof, , Which can cause unpleasant emotions to users.

Also, today's sealing tapes, when viewed by the naked eye, can not read the unique identification code (CVC) of a card that is attached to the surface of the card and is engraved therein, but when viewed from the side of the card with bright light or light, The unique identification code number (CVC) of the card can be easily read. In such a case, the unique identification code number of the card can be obtained by simply looking at the opposite side of the sealed tape adhering to the surface of the card with no light and light rays, There is a possibility of illegal use.

In conclusion, considering the various uses of today's plastic cards and their security requirements, it is necessary to keep the security even by the external rays or light when the seal tape is attached, It is necessary to develop a technology for sealing tapes that can further enhance or improve the security of the sealing tapes by allowing them to leave traces of use on the sealing tapes.

Prior art related to a security tape related to a conventional plastic card will be described below.

Korean Patent No. 10-400484 "Method of manufacturing a plastic card for forgery prevention" (September 22, 2003); Korean Patent No. 10-426629 "Tape-type security card with improved security and method for manufacturing the same" (March 29, 2004); Korean Registered Utility Model No. 20-194010 "Security Sticker for Identification Card" (June 16, 2000)

SUMMARY OF THE INVENTION The present invention has been made in order to solve all of the problems of the prior art described above, and it is an object of the present invention to provide a sealing tape which can secure security even by external light or light when attached with a sealing tape, And it is an object of the present invention to provide a method for manufacturing a seal tape which can further enhance the security of the seal tape.

In order to achieve the above object, the present invention provides a method of manufacturing a semiconductor device, comprising: (S 210) forming a first adhesive layer by applying a first adhesive to a PET base layer of a transparent thin film; (S 220) of weakening the adhesive force of the adhesive on the first adhesive layer and applying a releasing agent in the form of an identification pattern to form a releasing agent layer; (S 230) applying a color ink on the first adhesive layer and the release agent layer to form a basic color layer; (S 240) formed on the basic color layer to form a light absorbing layer that absorbs light when light is emitted from the outside; (A) formed in the form of an identification pattern of the release agent layer and an outer portion of the cut portion by cutting the interface between the light absorbing layer and the basic color layer and cutting the interface between the first adhesive layer and the release agent layer (S 250) forming a non-cut region (B); (S 260) applying a second adhesive on the light absorption layer to form a second adhesive layer; A finishing step (S 270) of applying final release paper on the second adhesive layer to finish final finishing; The present invention also provides a method of manufacturing a security tape for a plastic card.

The security tape manufactured by the present invention is used by attaching security information used for maintaining the security of the plastic card in a plastic card in order to protect internal financial information of the plastic card .

The security tape manufactured by the present invention is characterized in that security information of a plastic card can be safely protected both in a state of being attached to and detachment from a plastic card.

The security tape for a plastic card according to the present invention uses a first adhesive agent and a second adhesive agent having different adhesive strengths and forms a release agent on a surface of a first adhesive agent to form a predetermined pattern, Is cut off. Therefore, when the security tape for a plastic card according to the present invention is released from the surface of the plastic card to which it is adhered, the plastic card is surely dropped along the pattern of the release agent, so that it is evident that the plastic card has already been used by anyone .

Further, since the security tape for a plastic card according to the present invention is absorbed in all the light even when a strong light from the front side to the back side of the plastic card is observed while being attached to the back surface of the plastic card, The CVC number written on the inner side of the tape can not be known at all.

1 is a block diagram showing a method of manufacturing a security tape for a plastic card according to the present invention,
2 is a cross-sectional view showing a configuration of a security tape for a plastic card according to the present invention.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. It is to be noted that the accompanying drawings are only for explaining the technical idea of the present invention in detail and that the technical idea of the present invention is not limited thereto and that various modifications are possible. In the specification of the present invention, the same reference numerals are used for the same parts, and parts that can be easily created by those having ordinary skill in the art are omitted in the description of the present invention. .

The present invention provides a method of manufacturing a security tape (100) for a plastic card that covers and protects security information unique to a plastic card.

Generally, a security tape for a plastic card covers the security information of a card described on the back side of a plastic card, and when any person peels off the tape or looks at the tape, it causes a certain damage to the tape, To be exposed to the outside. In addition, when the plastic card is exposed to external light or a light beam in a state in which the plastic card is not attached to or detached from the security tape for the plastic card, the security information unique to the card described inside the security tape can be read Therefore, a technique capable of completely preventing such a phenomenon is necessary. The security information refers to the CVC, the PIN number, and other security-related information used to maintain the security of the plastic card, as described above.

The method for manufacturing a plastic card security tape 100 according to the present invention includes a step (S 210) of forming a first adhesive layer 120 by applying a first adhesive to a base layer 110 of a transparent thin film.

The base layer 110 of the transparent thin film forms the outer surface of the security tape for plastic cards, and is preferably a flexible and transparent PET sheet. The first adhesive layer 120 is formed on the transparent base layer 110 by applying an adhesive. The adhesive may bond the base layer 110 and the layers formed thereon to each other. However, in order to distinguish the adhesive strength between the base layer 110 and the second adhesive to be applied in a subsequent step, . As the first adhesive, a product commonly used in this technical field can be used.

The method for manufacturing a plastic card security tape 100 according to the present invention includes a release agent formation step (S 220) for forming a release agent layer 130 by applying a release agent in the form of an identification pattern on the first adhesive layer 120, .

The releasing agent is applied on the first adhesive layer 120 and is not applied to the entire surface of the first adhesive layer 120 but partially applied thereto and more specifically, . This is because when the releasing agent is applied, the adhesive force of the first adhesive layer 120 is weakened due to the nature of the releasing agent in the applied portion, and when the weakened portion is later partially peeled off from the base layer 110, So as to form an identification pattern. The identification pattern may include letters, numbers, and symbols. In the case of a character, it is preferable to include a word or warning that indicates that the security tape 100 has been used when the security tape 100 is uncovered or looked up.

The method of applying the releasing agent on the first adhesive layer 120 is not particularly limited. The release agent may be applied by spraying, or a liquid release agent may be formed on the surface of the rotating roller and then transferred onto the first adhesive layer 120. At this time, in the case of the spraying method, it is preferable that an empty space is formed with a predetermined identification pattern by using an auxiliary tool (not shown), and the releasing agent is injected into the empty space. When the identification pattern is composed of a letter, a number, a symbol, a word, or a warning, it is possible to use the letter, number, symbol, word or warning written in the auxiliary tool as a blank space.

The method for manufacturing a plastic card security tape 100 according to the present invention includes the steps of forming a basic color layer 140 by applying color ink on the first adhesive layer 120 and the releasing agent layer 130 230).

The color ink is an ink commonly used in the art, preferably a color that can be visually identified by the transparent base layer 110. The color that can be identified by the naked eye is not particularly limited, but it is preferable to exclude the yellow color which is not clearly recognized by the naked eye. This is because when the security tape 100 is used, a portion of the base layer 110, which is partially peeled off from the base layer 110 and then re-bonded to the base layer 110, So that they can be clearly identified by the naked eye.

The method of applying the color ink on the first adhesive layer 120 and the release agent layer 130 is not particularly limited. However, it is preferable to coat the surface of the roller with a roller in such a manner that the surface is transferred onto the first adhesive layer 120 and the release agent layer 130. If the roller is used, the color ink can be transferred onto the first adhesive layer 120 and the release agent layer 130 while pressing the color ink.

The method for manufacturing a plastic card security tape 100 according to the present invention is a method for manufacturing a plastic card security tape 100, which is formed on the base color layer 140 and which is capable of absorbing light or light when the light or light is reflected from the outside (S 240).

The light absorption layer 150 imparts a function of absorbing light or rays radiated from the outside to a security tape covering security information of the card described on the back side of the plastic card. Generally, when the basic color layer 140 is attached to the back side of a card, the security information of a card present inside the basic color layer 140 is not visible to the naked eye. However, when light is emitted from the outside, The security information of the card can not be prevented from being read by the naked eye. In order to solve this problem, the present invention forms a separate light absorbing layer 150.

The light absorbing layer 150 is preferably formed of an ink material containing a material capable of absorbing light or light beams radiated from the outside. Examples of the light absorbing material include black based powdered carbon, black based dyes, and black based pigments. Among them, black dye is better. The black dye may be used as an ink material, and when a black ink is used, the light absorbing layer 150 can be formed simply and easily in a conventional manner.

The method of applying the light absorbing layer 150 on the basic color layer 140 is not particularly limited. Therefore, it is preferable to proceed by a method of transferring from the surface of the roller to the surface of the basic color layer 140 by using a roller, though it may proceed in a jetting manner using an injector. When the rollers are used, the two color layers 140 and 150 can be formed as one single layer by pressing and pressing the light absorbing layer 150 on the basic color layer 140 to be.

A method of manufacturing a security tape for a plastic card according to the present invention comprises cutting the light absorbing layer 150 and the base color layer 140 so that the first adhesive layer 120 and the release agent layer 130 (S 250) for forming a cut region (A) in the form of an identification pattern of the release agent layer (130) and a non-cut region (B) .

The cut portion A is a portion formed by cutting the light absorbing layer 150 and the basic color layer 140. The cut portion A is formed while passing through the releasing agent forming step S 220 and the basic color layer forming step S 230 It is very important to cut along the boundary which is divided along the identification pattern formed by the release agent. This is because the cut portion A is formed so that the remaining portion is divided into the non-cut portion B and the difference in adhesion between the cut portion A and the non-cut portion B is effectively utilized later In order to make it possible. In other words, the release agent layer 130 is present between the base layer 110 and the basic color layer 140 at a portion belonging to the cut portion A, whereas the release agent layer 130 exists between the base layer 110 and the basic color layer 140, The releasing agent layer 130 is not present between the base layer 110 and the base color layer 140 so that the adhesive strength to the base layer 110 at the cut portion A is less than that of the non- Is much weaker than the adhesive force to the base layer 110 at the region B.

The cutting region A is preferably formed on the surface of a roller (not shown) using a blade having the same shape as the identification pattern of the release agent layer 130. Since this method is known as a conventional roller cutting method, a more detailed description will be omitted.

The method for manufacturing a plastic card security tape 100 according to the present invention includes a step (S 260) of forming a second adhesive layer 160 by applying a second adhesive on the light absorbing layer 150.

The second adhesive is an adhesive having an adhesive property and is applied including both the cut portion (A) and the non-cut portion (B). The coating method of the second adhesive is not particularly limited. The second adhesive layer 160 is attached to the back surface of the plastic card and exerts a strong adhesive force.

The adhesive of the second adhesive layer 160 is weaker than that of the first adhesive of the first adhesive layer 120. If the adhesive force of the adhesive of the second adhesive layer 160 is stronger than the adhesive force of the first adhesive layer 120, the function as a security tape can not be attained.

The method for manufacturing a plastic card security tape 100 according to the present invention includes a finishing step (S 270) of finishing a final release by attaching a release paper to the second adhesive layer 160; .

The release paper (not shown) is generally used, and is used to prevent the second adhesive layer 160 from being contaminated by external contaminants and to maintain the quality of the product. This is a typical one, so a detailed description thereof will be omitted.

After completion of the above steps, the finished plastic card security tape 100 is cut into appropriate widths and lengths, is manufactured, then shipped to the market and attached to the back of the plastic card. The security tape 100 for a plastic card is firmly adhered thereon so as to cover security information of the plastic card, as described in detail above.

When the security tape 100 attached to the back side of the plastic card is removed, in the process of separating the security tape 100 from the surface of the back side of the card, The adhesive force is weakened by the releasing agent 130 and a phenomenon that the adhesive agent is slightly swollen is generated. On the other hand, in the portion belonging to the non-cut portion B, since the first adhesive layer 120 is still firmly attached to the rear surface of the plastic card, no lifting phenomenon occurs. Therefore, although the part belonging to the cut part A is reattached to the rear surface of the plastic card, unlike the uncut part B, complete adhesion is not obtained. Therefore, the cut part A and the non- The site B is clearly distinguished by the naked eye.

As a result, if the third party, not the end customer, prefers the security tape 100 of the present invention, which is attached to the back surface of the plastic card, and tries to find the security information of the card inside the security card by stealing it , The cut portion (A) and the non-cut portion (B) are clearly exposed on the security tape (100). Accordingly, the security tape 100 of the present invention can secure the security of the plastic card.

On the other hand, since the security of the case where the security tape 100 of the present invention is attached and light or rays are irradiated on the back surface thereof has been described in detail above, it will not be described repeatedly.

While the present invention has been particularly shown and described with reference to the preferred embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, The range is determined and limited by the claims.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the scope of the present invention.
