Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a prepaid sheet that allows only legitimate users to check invisible information such as a password, and more particularly to a prepaid sheet that can be manufactured at a low cost.
[0002]
[Prior art]
For example, when using a prepaid mobile phone, the user purchases a prepaid card, and after confirming the PIN number hidden as invisible information on the prepaid card by rubbing it with a nail or a coin The mobile phone can be used by inputting the personal identification number into the mobile phone.
[0003]
In this prepaid card, for example, the surface of the personal identification number printed on the surface of the base material is concealed by a shielding ink layer. The actual situation is confirming the number.
[0004]
[Problems to be solved by the invention]
Thus, as a prepaid sheet used for a prepaid card of a mobile phone, etc., it is necessary to print information such as a personal identification number on the card base material, and to coat a shielding ink layer so as to conceal the surface. In addition to a printing process such as a code number, a problem has been pointed out that the coating process of the shielding ink layer is bulky and causes an increase in cost.
[0005]
Further, since the shaving ink layer is scraped when the personal identification number is confirmed, there is a problem that the appearance of the card is deteriorated and shavings and the like are scattered around.
[0006]
Also, this type of card is a kind of cash voucher, and strict management is required for its manufacture, storage, etc., and dealers are also required to handle it with sufficient care.
[0007]
The present invention has been made in view of such circumstances, and it is an object of the present invention to provide a prepaid sheet that can be manufactured easily and inexpensively without causing scraps or the like when confirming a personal identification number.
[0008]
[Means for Solving the Problems]
In order to achieve the above object, the invention according to claim 1 of the present application is provided with a thermosensitive coloring layer on the surface of the base sheet, and on the thermosensitive coloring layer, invisible information consisting of numbers or letters is formed by transparent ink. It is formed.
[0009]
Further, in the invention according to claim 2 of the present application , a thermosensitive coloring layer is provided on the surface of the base sheet, and on the thermosensitive coloring layer, invisible information consisting of numerals or letters is hollowed out. Or the transparent ink is apply | coated around the character .
[0010]
Furthermore, the invention described in claim 3 of the present application is characterized in that invisible information is formed by a thermal printer.
[0011]
Here, as the base material sheet, paper materials such as synthetic paper and neutral paper, and synthetic resin sheets such as polyester (PET) and polypropylene (PP) can be used, and the paper material is used as the base material sheet. When used, it is possible to use thermal roll paper provided with a thermosensitive coloring layer on the surface of the paper material.
[0012]
Furthermore, the transparent ink formed on the surface of the thermosensitive coloring layer is excellent in surface lubricity and uses an ink having a small resistance value against friction, and invisible information such as a password is in a positive or negative state. It is formed as follows.
[0013]
As is apparent from the above configuration, if the invisible information area of the prepaid sheet according to the present invention is rubbed with a nail or a coin, a transparent ink layer is provided due to a difference in frictional resistance between the thermosensitive coloring layer and the transparent ink. The heat-sensitive color developing layer at the uncolored portion develops color, and invisible information such as a code number appears.
[0014]
Therefore, conventional scraps and the like are not scattered around and the appearance of the prepaid sheet itself is good. Furthermore, since transparent ink should just be apply | coated on the thermosensitive coloring layer of a base material sheet, a man-hour can also be simplified. In particular, if it is made using a transparent ink ribbon by a thermal printer, it can be made whenever necessary, and it is not necessary to store it as a cash voucher, which is extremely convenient in terms of management.
[0015]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of a prepaid sheet according to the present invention will be described in detail with reference to the accompanying drawings.
[0016]
FIG. 1 is a front view showing an embodiment in which the present invention is applied to a prepaid card of a mobile phone, FIG. 2 is a cross-sectional view of the prepaid card, and FIGS. 3 and 4 show invisible information in the prepaid card. FIG. 5 is an explanatory view showing a management form of the prepaid card.
[0017]
First, as shown in FIGS. 1 and 2, the prepaid card 10 is provided with a thermosensitive coloring layer 30 on the surface of a base sheet 20, and a transparent ink 40 is further printed on the surface.
[0018]
The transparent ink 40 is excellent in surface lubricity, has very small frictional resistance, and is printed in a concealed state so that the code number 50 appears positively.
[0019]
For example, if the personal identification number 50 is set to four digits of 1, 2, 3, and 4, when the transparent ink 40 is printed, 1, 2, 3, and 4 are cut out in the invisible information area 11 (inside Printing is performed around the punched portion so as to be in a state of 41).
[0020]
Therefore, in the state shown in FIG. 1 and FIG. 2 where the prepaid card 10 is issued, since the personal identification number is formed by the transparent ink 40, the personal identification number 50 cannot be read and the personal identification number 50 is given to a third party. There is no leakage.
[0021]
Then, the user rubs the invisible information area 11 of the issued prepaid card 10 with a nail or a coin, so that the surface of the transparent ink 40 has good sliding property, and thus heat generation is suppressed to a low level. In the hollowed out part 41, the thermosensitive coloring layer 30 generates heat due to frictional heat, and the colored part 31 develops color, so that the code numbers (1, 2, 3, 4) are as shown in FIGS. Appears clearly.
[0022]
Of course, the number itself may be printed with transparent ink so that the PIN number appears as a negative.
[0023]
Therefore, in the prepaid card 10 according to the present invention, no scraps or the like are generated when the personal identification number 50 is confirmed. Therefore, the prepaid card 10 itself is not contaminated by the scraps and attached to the surroundings. The problem of scattering etc. can be prevented beforehand.
[0024]
Also, a printing process in which the transparent ink 40 is simply printed around each number constituting the code number 50 so that the code number 50 is in a hollowed state with respect to the substrate sheet 20 coated with the thermosensitive coloring layer 30. Thus, the production cost of the prepaid card 10 can be reduced.
[0025]
Next, when the prepaid card 10 is created by a thermal printer, the management form will be described. The card A before issuance is one in which the thermosensitive coloring layer 30 is provided on the surface of the base sheet 20, and this pre-issuance card 10 is The card A is printed with a printer 60 using a transparent ink ribbon in a state in which the code number 50 is hollowed out, and the above-described prepaid card 10 is issued. Thereby, storage and management of a cash voucher become unnecessary.
[0026]
When the user rubs the surface of the invisible information area 11 of the purchased prepaid card 10, the code number 50 appears. Therefore, the user reads the code number 50 and inputs the code number 50 to the mobile phone. You can use a mobile phone later.
[0027]
On the other hand, when the prepaid card 10 is issued to the terminal-side computer 70 connected to the printer 60, predetermined information is input, and data is input from the terminal-side computer 70 to the management host computer 80. The frequency is managed by the host computer 80.
[0028]
Although the embodiment described above has been described with respect to the use of the prepaid card 10 of the mobile phone, it can be applied to a prepaid seat generally used for a prepaid service in which only a legitimate user can check a personal identification number, etc. Application to instant lotteries is also possible.
[0029]
【The invention's effect】
As described above, according to the prepaid sheet according to the present invention, since no shielding ink layer is required, no shaving residue or the like is generated at the time of information confirmation. This has the effect of effectively solving the problem of scattering.
[0030]
Furthermore, according to the prepaid sheet according to the present invention, the transparent ink may be printed so that invisible information is formed on the thermosensitive coloring layer on the surface of the base sheet. , Prepaid cards can be produced easily and inexpensively, leading to significant cost reductions, and confidential information is not leaked to a third party, and the card can be stored and managed as a voucher at a store or the like. It has the effect of becoming unnecessary.
