Abstract

(57) [Abstract] [Purpose] To obtain a non-contact type prepaid card with low cost, long life and high security level by an image processing device. [Structure] A prepaid card is used. The prepaid card has a two-dimensional pattern 13 formed on a mount 11, and the surface of the pattern 13 is covered with a light-transmitting coating outside the visible light region.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a prepaid card that is identified by image processing.

[0002]

[Prior art]

 There are contact type and non-contact type prepaid cards. Among the contact type, magnetic cards are the most popular, and recently, the non-contact type micro wave type is beginning to spread.

[0003]

[Problems to be solved by the device]

 Each of these conventional methods has merits and demerits, and it is cheap to use a magnetic card, but the processing speed is slow and the contact portion is consumed. In addition, the strong electromagnetic field that can be placed in factories has a large effect, and it is easy to falsify and the security level is low.

Although the security level is high in the case of using a microwave, the card is thick and expensive when used as a card.

It is also possible to use a barcode, but the surface of the barcode is easily scratched and has a single life.

The present invention provides a non-contact type system that is inexpensive, has a long life, and has a high security level by combining an image processing device and a card.

[0007]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention comprises a substrate, a two-dimensional image pattern recorded on the substrate, and a light-transmitting film laminated on the pattern, a prepaid card. .

[0008]

[Operation] The pattern of each card is a two-dimensional pattern, and the number of changes is almost infinite. The pattern of each card is converted into an electric signal and registered in advance in the image processing device. When the card carrier brings the card closer to the camera of the image processing device, the edge of the card triggers the image processing device, and the camera images the pattern through the light-transmitting film of the card. Can be recognized by searching and comparing with the recognition pattern of each person stored by being converted into an electric signal by image processing.

[0009]

【Example】

 The recognition card has a pattern 13 on a mount 11 as shown in FIG. The pattern may be, for example, a dot pattern or a curved pattern, and in any case, it needs to be photographable by a camera.

The pattern 13 is tightly covered with the coating 12. When the film 12 is an infrared transmissive film, a CCD element is used as the light receiving element of the image forming part of the camera, and the transmissive region is 0.8 to 1.1 micrometers and is invisible. Then, halation can be prevented by the coating film 12 when the pattern is imaged. The camera has CCD elements located in the optical system so as to match the pattern.

[0011]

[Effect of device]

 According to this invention, a thin card can be adopted as compared with the one using a transponder which has been conventionally used for ID management. And because the pattern applied to the card cannot be invested, it is fully secure, inexpensive and has a long life.
