Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a magnetic recording type card, in which a fuse is incorporated in a circuit of the card and capacity data representing data content is added by a fuse body. The present invention relates to a magnetic recording card having a function of determining the authenticity of cards such as tickets and admission tickets and a function of preventing unauthorized use.

[0002]

2. Description of the Related Art Various functions are added to current cards to prevent unauthorized use such as authenticity, duplication, etc. The authenticity judgment function used in current magnetic recording cards is magnetic recording. By providing on the surface a magnetic barcode made by combining a soft magnetic material having a coercive force of 40 (Oe) or less and a filling material having no coercive force, each magnetic recording card can be easily forged or altered. I'm preventing.

In addition to magnetic barcodes, fixed data such as optical barcodes and IR barcodes (barcodes for infrared detection) are added, and a magnetic shield layer made of a soft magnetic material having high magnetic permeability is provided on the magnetic recording layer. To prevent reuse by providing a punching hole in a part of the card at the time of use, and special measures such as special coding of data and data scrambling from the software aspect, magnetic card To prevent unauthorized use of certain types.

[0004] However, despite measures to prevent unauthorized use of magnetic cards as described above, in today's widespread society of cards, various alterations,
Falsification and unauthorized use have become a problem, and new countermeasures and systems are constantly being demanded.

[0005] The present invention meets the above-mentioned demand, and a capacitive data card having an electrode part forming a part of a capacitor circuit is receiving attention.

[0006] This prepaid card system of the capacity type was disclosed on July 21, 1981 in US Patent No. Registered as 4280119. In addition, International Application Publication WO95 / 142 on May 26, 1995
The prepaid card system described in the specification of No. 85 incorporates a fuse in the circuit of the capacitive data card, and the fuse has a predetermined resistance value when it is in an intact (non-burned) state. FIG. 1 shows a system in which when a fuse is burned out, the resistance value increases to infinity, so that a bit of data is represented by the resistance state of the fuse.

This capacitive data card is shown in FIG.
As shown in FIG. 2, a circuit 13 having a capacitor can be formed only when the card 10 is integrated with the sensor unit 12 formed on the reading device side.

The card unit 10 includes a resistor R serving as a fuse.
11 and electrode portions 11a and 11b forming a part of a capacitor to be connected and connected to each end of the resistor R11. An opposite electrode of a capacitor connected and connected to each terminal of the power supply 14 is formed in the sensor portion 12. The respective electrode portions 12a,
When the card section 10 is set in the sensor section 12 (write head) of the input / output device, the counter electrodes 11a and 12a and the counter electrodes 11b and 12b An air condenser 13 facing each other at a distance d and sandwiching air between the facing sides;
A closed circuit having a and 13b is formed.

In the closed circuit 13 thus formed, a high voltage V is applied to the resistor R11 (fuse) by the power source 14.
, The resistor R11 is burned out by the high current, so that the circuit using the resistor R11 is used, and the resistor R11 that has not been burnt becomes an unused bit.

As described above, one resistor R1 of the card unit 10
A 1-bit signal is given by one closed circuit of 1 and a data card capable of storing a signal having a required number of digits by forming an arbitrary number of closed circuits in the card unit 10 can be formed. Become like

In the above-mentioned capacitive data card, the bit can be changed from unused to used by burning off the resistor R11. Therefore, the reverse data reproduction (returning the burnt-out fuse to the original state) is easily performed. Can not do.

Therefore, although data reproduction is not easy, there is an advantage that falsification is prevented and reliability is high, but a certain limit is imposed on updating of data stored in the card, and its utility value is increased. However, there was a problem that it could not be fully exhibited.

[0013]

By the way, in order to solve the above-mentioned problems, a configuration having a magnetic storage area for storing magnetic data in a capacitive data card has been considered. For example, Japanese Patent Application Laid-Open Nos. 9-
No. 305721.

The present invention is a card in which a magnetic storage area for storing magnetic data is added to the above-mentioned capacitive data card. The card has the advantage that the data is not easily reproduced, so that tampering is prevented and the reliability is high. An object of the present invention is to obtain a card having a high use value in which no limitation is imposed on updating data stored in the card.
