Abstract

(57) [Summary] [Purpose] The purpose is to prevent the forgery of prepaid cards. [Structure] A magnetic recording layer 5, an infrared reflective layer 4, and a bar code 3 are provided on a card substrate, and a concealing layer 2 and a protective layer 1 are disposed on the magnetic recording layer 5. Is.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a prepaid card having a magnetic recording unit.

[0002]

[Prior art]

 Conventionally, there has been a prepaid card in which a magnetic recording layer is provided on a substrate and a protective layer is provided thereon. The magnetic recording of the prepaid card is performed by utilizing the saturation residual magnetic flux of the hysteresis characteristic of the magnetic recording layer in the magnetic field, and the recorded information can be permanently stored, easily erased and written, and has a high recording density and many Information can be recorded.

[0003]

[Problems to be solved by the device]

 However, the conventional prepaid card has a drawback that it is easy to forge because information can be recorded and erased easily.

An object of the present invention is to provide a prepaid card which can prevent the forgery of the prepaid card.

[0005]

[Means for Solving the Problems]

 A prepaid card according to the present invention comprises a magnetic recording layer for recording magnetic data, which is provided on a card substrate, an infrared reflecting layer for reflecting infrared rays, and a bar code for absorbing infrared rays. The concealing layer and the protective layer have a laminated structure.

[0006]

[Action]

 The prepaid card according to the present invention is provided with a bar code (records identification information) on the magnetic recording layer, and this bar code is recorded so as to be identifiable by reflected light of infrared rays. Therefore, even if it is attempted to forge only the magnetic recording layer as in the past, this illegal use is impossible.

In other words, the reader / writer first irradiates the prepaid card with infrared rays and cannot read the bar code by infrared reflected light in the card in which the magnetic recording layer is simply forged. In this way unauthorized use is prevented.

[0009]

【Example】

 An embodiment of the prepaid card according to the present invention will be described with reference to the sectional view of FIG. In FIG. 1, C is a prepaid card, and this prepaid card C comprises a base 6 made of resin or the like and a magnetic recording layer 5 laminated on the base 6, and the magnetic recording layer 5 has magnetic data such as a monetary value. Is recorded.

An infrared reflection layer 4 having a predetermined thickness is provided on the magnetic recording layer 5, and a bar code 3 (identification information, for example, store number is recorded) that absorbs infrared rays on the infrared reflection layer 4. Is provided, the bar code 3 is covered with a hiding layer 2, and a protective layer 7 is provided on the hiding layer 2.

The infrared reflection layer 4 and the bar code 3 are configured to be distinguishable by reflected light of infrared rays. That is, the infrared reflective layer 4 is formed using an ink having a high infrared reflectance, and the bar code 3 is formed by applying or printing an ink having a high infrared absorptivity. The hiding layer 2 is an ink that transmits infrared rays but not visible light, and the protective layer 1 is formed by lamination of a synthetic resin film or the like.

When the prepaid card 1 configured as described above is inserted into the reader / writer, infrared rays are radiated from the infrared irradiation head inside the reader / writer to the prepaid card 1, hit the bar code 3, and are absorbed by the reflection layer 4. Is reflected. By receiving this reflected light, the bar code information is detected and the prepaid card C is identified. That is, it is checked whether or not there is the bar code 3, and if so, whether or not the data of the bar code 3 is correct.

After that, the magnetic data is read by the reader / writer, and a new balance is recorded on the magnetic data of the magnetic recording layer 5 by the reader / writer according to use. When the magnetic recording is simply forged on the magnetic recording layer 5 of the prepaid card C as in the conventional example, and the barcode 3 is not read by infrared rays when used as a reader / writer, the prepaid card 2 is illegal. The prepaid card C that has been used is discriminated and the inserted prepaid card C is ejected from the reader / writer to prevent forgery.

[0014]

[Effect of device]

 Since the prepaid card according to the present invention is provided with the bar code utilizing the reflected light of infrared rays inside the prepaid card, it is possible to further prevent forgery and illegal use.
