Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a card information recording method in which a magnetic stripe and an IC module are attached to a card, and a card recording method of which reliability is improved by recording and storing information in both.

[0002]

2. Description of the Related Art In recent years, chip cards in which IC chips such as microcomputers and memories are mounted or built-in,
Research has been conducted on cards called memory cards, microcomputer cards, electronic cards, etc. (hereinafter referred to as IC cards). Since this IC card has a larger storage capacity than the conventional magnetic stripe card, it is considered to record and store the history of deposits and savings in place of a bankbook for banking and the history of transactions such as shopping for crediting. .

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of such circumstances, and an object thereof is to provide a card recording method capable of improving the reliability of an IC card.

[0004]

SUMMARY OF THE INVENTION According to the present invention, a part or all of information stored by providing an IC module and a magnetic stripe together on the same card, for example, an ID code such as an individual name and a bank account number, and a final information. By recording / storing the balance or ID code and the final balance in both the memory section of the IC module and the magnetic stripe, even if one of them loses the stored data due to damage or the like, one of them assists. It is the one.

[0005]

As described above, since the IC card has a large storage capacity and can store transaction history (information), the offline method has a great merit, not the online method like the current CD card. Has been done.

However, since information is stored only in the memory section of the IC module, and if the IC module stops functioning, the stored information disappears, not only the card issuer but also the card user. It will be a great trouble for me. Especially IC
In the case of a chip, even if it is made into a module, it is vulnerable to static electricity, moisture, etc. from the outside, which may cause a function stop such as data destruction. Also, the chip bonding portion in the IC module may be broken due to external pressure due to bending of the card or the like. On the other hand, the magnetic stripe card has a weak point that data is lost due to the influence of external magnetism.

The present inventors have installed an IC module and a magnetic stripe on the same card in order to solve the above problems.
Data such as ID code and final balance, which are the most important data for the card issuer and card user, can be recorded and stored in the memory of the IC module and the magnetic stripe in a duplicated manner so that one of the data can be backed up. By redundantly recording and storing data, one of them has a backup function for the loss of data. The card issuer determines the content of the duplicated data, but if the ID code and the final balance are recorded for verification of the person in question,
Trouble between the card issuer and the user will be avoided. It is up to the card issuer whether to duplicately record the personal identification number in the ID code. Further, when recording on the magnetic stripe, it is not necessary to record all transaction history data from the storage capacity, but if the recorded data in the memory section of the IC module matches the storage capacity of the magnetic stripe,
Recording of all data would be possible.

Embodiments of the present invention will be described below with reference to the drawings. As shown in FIGS. 1 and 2, an IC module 3 is provided in a part of the center core 15, and the oversheets 14 and 14 are provided on the front and back surfaces of the contour core 15.
The magnetic stripe 2 is provided on the surface of the oversheet 14, and the printed pattern 4 is provided between the sencota core 15 and the oversheet 14,
A card 1 in which the magnetic stripe 2 and the IC module 3 of the present invention are provided side by side is configured. If necessary, embossed characters 5 can be applied as shown in FIG. Incidentally, the positional relationship of the above-mentioned respective parts is not particularly limited, and for example, as shown in FIG. 3 and FIG. 4 which is a sectional view thereof, the IC module 3 may be provided on the front surface of the card, while the magnetic stripe 2 may be provided on the back surface of the card. . Also, the shape of the IC module is not particularly limited.

If the IC module 3 is described in detail, it is as shown in FIG. That is, an IC chip 9 such as a microcomputer and a memory is surrounded by an epoxy resin 11 except for the upper surface, a circuit 7 is provided on the upper surface of the IC chip 9, and the IC chip 9 and the circuit 7 are connected by a lead wire 10. On the other hand, the surface of the IC module 3 is provided with an electrode 6 in contact with an external connection terminal, the electrode 6 and the circuit 7 are held by a substrate 8 such as a glass epoxy film, and the electrode 6 and the circuit 7 are connected. Are conducted by through holes (not shown). In addition, as a flow stop for the epoxy resin 10 when the IC module 3 is manufactured, I
A glass epoxy film frame 12 is provided on the side of the C module 3.

The IC module 3 having the above structure is attached to the concave portion of the card 1 by the adhesive 13. What is illustrated here is a hard vinyl chloride plastic card specification, and the card 1 is composed of the center core 15 and the oversheet 14, but the specification is not particularly limited to this specification. Incidentally, the recording / storing method of the information on the magnetic stripe and the IC memory in the IC module is performed by a commonly used method.

[0011]

As described above, in the card of the present invention, the magnetic stripe and the IC module are provided side by side in one card,
Information is recorded and stored in duplicate on both sides, and even if the information on one side disappears, the information remains on the other side, so that the reliability of the card is greatly improved.
