Description

Description: TECHNICAL FIELD The present invention relates to an information card such as a magnetic card in which value information such as a balance and a balance is recorded, and a processing device therefor.

[Prior Art] In recent years, prepaid cards (hereinafter referred to as information cards)
Has become popular and is used in card-type vending machines and ticket vending machines. In this case, the information card reads all the information, performs necessary processing such as subtracting the sales amount, writes the processing result again on the card, and returns it. However, since all the data is read and written by this method, the processing time becomes long and the wear of the magnetic head also increases.
-127903 publication, data that does not require rewriting when used, that is, system code,
The fixed information section in which data such as ID code, card issue date information, expiration date information, card issuing machine number, etc. is written, and the data that needs to be rewritten at the time of use, that is, balance value information and card usage date etc. are written. There is a proposal that is composed of a variable information section. By doing so, since data writing only needs to be performed in the variable information section, the processing time is shortened and the wear resistance of the magnetic head is improved.

In order to standardize the information card with such a configuration, the same shape is often used for any vending machine, but by changing the identification code for each system,
After that, I use a standardized format. That is, as shown in FIG. 5, for example, there is information card 1 and the information card 2 for soft drink for cigarette vending machines, information card 1 is written in the specific cigarette vending machine system identification code 1 ₁ a fixed information section 1 _2, and a variable information portion 1 ₄ written in balance value information 1 _3. Information card 2 similarly, the fixed information unit 2 ₂ which has been written in the soft drink vending machine unique identification code 2 _1, and a variable information section 2 ₄ written in balance value information 2 _3. The information card 1 for the cigarette vending machine can be used normally when used in the reader / writer 3 for the cigarette vending machine system, and the information card 2 for the soft drink vending machine is used for the soft drink vending machine system. It can be used normally when used for the dedicated reader / writer 4. If this is used for a reader / writer of another system as shown by a dotted arrow, it cannot be used because the identification code is different, and confusion does not occur even if the shape is the same.

By the way, it is often the case that a person in a special position such as a maintainer of each device can freely modify the data of the variable information part to some extent. There is no problem as long as you modify such data on your own card, but it is necessary to rewrite the data in the variable information part of the information card of other systems, for example, the one whose residual value is lost by use. If this happens, the problem of unauthorized use will occur.

In order to prevent such fraud, as disclosed in Japanese Patent Laid-Open No. 61-123056, there is a method in which a hole corresponding to the balance value is discontinuously formed in the card and the position and the balance value information are collated. Proposed. Further, as disclosed in Japanese Patent Laid-Open No. 58-99878, it has been proposed to make counterfeiting a card difficult by providing a conversion information body separately from the magnetic stripe.

[Problems to be Solved by the Invention] However, the former requires a reading means other than the punch mechanism and the magnetic head, which complicates control and configuration, and the latter requires processing in addition to the magnetic stripe. However, there is a problem that the shape becomes large and the economical efficiency is deteriorated.

[Means for Solving the Problem] In order to solve such a problem, an identification storing a system-specific second system identification code rewritten by the balance value information area and the card writing means in the variable information section of the information card. A code area is provided, and the card writing means, a memory storing a system identification code unique to the system, and the first and second system identification codes are read based on the insertion of the information card in the information card processing device, Transaction permitting means for permitting transaction processing when each system identification code matches the system identification code stored in the memory is provided.

Further, a control means for rewriting the second system identification code on the card to the system identification code stored in the memory after the coincidence detection by the transaction permitting means is provided.

Also, a control means is provided for rewriting the second system identification code on the card to the system identification code stored in the memory when rewriting the value information.

[Operation] When the information card is inserted, the first identification code of the fixed information section and the second identification code of the variable information section of this card are read to detect a match with the identification code stored in the memory, When a match with the identification code of is detected,
Allow transaction processing. Then, when rewriting the value information, the second identification code on the information card is rewritten to the identification code stored in the memory. Therefore, for example, using a card processing device for a cigarette vending machine to illegally rewrite the value information of a card for selling soft drinks, insert the rewritten card into the card processing device for a soft drink vending machine. However, since the second identification code of the variable information part of the card has been rewritten, it is determined that the card is illegally used and the transaction is not allowed.

[Embodiment] FIG. 1 is a view showing an embodiment of the present invention. For example, there are an information card 10 for a cigarette vending machine and an information card 20 for a soft drink, and the information card 10 is a cigarette vending machine. Fixed information section 10 with system-specific identification code 10 ₁ written
₂ and the variable information section 10 _{4 in} which the identification code 10 ₁ and the balance value information 10 ₃ are written. That is, the same identification code 10 ₁ is written in both the fixed information section 10 ₂ and the variable information section 10 ₄ . Information card 20 as well,
A soft drink vending machine unique identification code 20 ₁ of the written fixed information section 20 _2, and a variable information portion 20 ₄ written identification code 20 ₁ and the balance value information 20 _3. And the information card 10 for the cigarette vending machine can be used normally when used in the reader / writer 30 dedicated to the cigarette vending system, and the information card 20 for the soft drink vending machine is dedicated for the soft drink vending system. It can be used normally when used for the reader / writer 40. By doing so, for example, even if the data of the variable information section 20 ₄ of the information card 20 for soft drinks is rewritten by the reader / writer 30 for the cigarette vending machine, the automatic information of the cigarette is sold in the variable information section 20 _4. the identification code 10 ₁ will be written for the machine. Thus the information card 20 rewrites the balance value of the variable information 20 ₄ for soft drinks writer
When used for 40, both the data of the fixed information part 20 _{2 and} the data of the variable information part 20 ₄ are read there. And although the identification data written therein matches are compared with the reader writer 40 is taken, the reader writer 30 for the cigarette vending machine identification code previously written in the variable information 20 ₄
Since rewritten, the identification code 20 instead of _1,
And it has a identification code 10 _1. However, what is written in the fixed information section 20 ₂ is the identification code 20 ₁ . Therefore, the identification code compared by the reader / writer 40 is not detected as a match and is determined to be an unauthorized use.

FIG. 2 is a functional block diagram of this device.
The motor control unit 51, the magnetic data read / write unit 52, the card position detection unit 53, the ROM 54, and the RAM 55 are connected by a bus, and an identification code for each terminal is written in the ROM 54. FIG. 3 is a circuit diagram, and FIG. 4 is a flowchart showing these operations. The operation will be described with reference to these figures. When the operator inserts the information card into a slot (not shown) (step 100), the sensor S1 in FIG. 3 detects this and causes the pulse motor PM to rotate forward, The information card is taken into the apparatus by the rollers R3 and R7 and the conveyor belt V1. And the top of the information card is the sensor
When S2 is reached, the magnetic data read section (magnetic head MH
Etc.) to read the identification code of the fixed information section of the information card and collate it with the identification code written in the ROM (steps 101, 102). As a result of the collation, if the identification codes do not match, the service ends there and the card is ejected (step 108).

If they match, read the identification code in the variable information section,
103) Matches with the identification code written in ROM. As a result of the collation, if the identification codes do not match, the service ends there and the card is ejected (step 108). If they match, the card data such as the remaining number of cards is sequentially read, this is recorded in RAM, and when the card head reaches the sensor S3, the pulse motor PM is stopped to finish reading the card data, Set to standby state.

The data recorded in RAM is analyzed by the CPU and the service is started by notifying the user (step 10).
Four). When the service ends (step 105), the pulse motor PM is rotated in the reverse direction, and the card data such as the card remaining amount and the identification data written in the ROM are transferred to the variable information section of the information card when the card rear end reaches the sensor S2. Write (step 106). Then, the information card is discharged (step 107), and the whole process is completed.

Although the identification data of the fixed information part and the identification data of the variable information part are read separately, they may be read continuously and the identification codes of the fixed information part and the variable information part may be collated in order. Alternatively, the information card may be ejected (returned) by passing the head once, recording the remaining amount at the time of normal rotation again, and then re-rotating again. The information card is not limited to a magnetic card as long as it has a fixed information section and a variable information section.

[Effects of the Invention] As described above, when the information card is inserted, the identification code stored in the memory by reading the first identification code of the fixed information section and the second identification code of the variable information section of the card. When the value is rewritten, the second identification code on the information card is changed to the identification code stored in the memory. Since the rewriting is performed, even if there is a person who can modify the variable information section data of his own system, the modification of the card of the other system can be prevented, so that there is an effect that fraud does not occur.
