2. Description of the Related Art There has been a card reader / writer which performs data recording / reproducing processing of different types of cards such as a magnetic card and an IC card by itself (Japanese Patent Laid-Open No. 7-446).
No. 62), there are only cards that are magnetic stripe-only cards, IC-only cards, or cards that can be used for only one purpose even if they are both. In other cases, terminals are often
Both the C-card reader / writer and the magnetic card reader / writer were installed, and the corresponding software was provided to the terminal to support the operation. For example, when different types of cards are inserted into one terminal at random, it has been impossible for the device to cope with the situation as appropriate. Bank cash dispensers and ATMs (Automated Teller Machines) have a common standard between banks, and are programmed to automatically process on the device side. If inserted into the machine, the machine would reject it.
When compared by card type, IC cards tend to switch from magnetic cards to IC cards because they can store more information than magnetic cards and have high security. During this transition period, one financial institution
Even if the reader is completely replaced in order to switch the magnetic card to an IC card, in the current situation where financial institutions are getting into each other, if there is a financial institution that cannot replace the device, it will be used conventionally. The magnetic stripe cannot be removed. That is, for a while, many cards including bank cards use the magnetic stripe together with the IC card even after switching to the IC card system.

BRIEF DESCRIPTION OF THE DRAWINGS FIG.
A method of controlling the reader / writer for the IC card will be described.

FIG. 1 is a diagram for explaining the concept of a method for controlling a magnetic / IC card reader / writer of the present invention, and FIG. 2 is a diagram for explaining an example of a magnetic / IC card reader / writer. FIG. 3 is a diagram for explaining an example of a magnetic recording format using a magnetic stripe, FIG. 4 is a diagram for explaining another example of a magnetic recording format using a magnetic stripe, and FIG. 5 is a flowchart for explaining a procedure for guiding a card to an appropriate recording unit by a control method of an IC card reader / writer.

In FIG. 1, when a card 2 having a magnetic stripe and an IC module is inserted into a reader / writer 1 for both magnetic and IC cards, a first magnetic recording section 11 having a magnetic recording / reproducing head causes a magnetic field. Reads magnetic data on stripes, and uses a magnetic / IC card reader
The collation is performed via the control unit 14 with the collation format 15 stored in the writer 1. Next, the card is transported to the second magnetic recording unit based on an instruction from the control unit. IC based on the format recorded on the magnetic stripe
If there is a transport instruction to the recording unit, the card is transported to the IC recording unit. In FIG. 1, the first magnetic recording unit and the second magnetic recording unit are described separately for easy understanding. However, the second magnetic recording unit may be replaced with the first magnetic recording unit.
This will be described with reference to FIG. As a recording method of the second magnetic recording unit and the IC recording unit, a case where data inputted from a terminal keyboard is directly inputted, a case where the data is temporarily recorded in an external customer database, and a part of the contents are recorded on a card. There are two types when recorded. The format collation described above will be described with reference to FIGS. 3 and 4.

In FIG. 2, when the card 2 is inserted into the reader / writer 1 for both magnetic and IC cards, the magnetic recording format recorded on the card 2 is changed by the magnetic recording / reproducing head 11 of the first magnetic recording section. Read. The features of the information written on the magnetic stripe are read, collated with the collation format, and if data rewriting of the magnetic recording unit is necessary, a read / write unit control unit (not shown) 1
6, the unit is moved downward, and the card is conveyed to the second magnetic recording / reproducing head 12 of the second magnetic recording unit. If data rewriting to the IC chip is necessary, read
The unit is moved upward by the light unit control unit 16, the card is transported to the IC recording unit, and the contact 13 of the IC recording unit comes down to the external connection terminal surface of the IC card.

In the description of FIG. 1, the reason that the second magnetic recording unit can be replaced by the first magnetic recording unit is that the card 2 is inserted into the magnetic / IC combined reader / writer 1 in FIG. Read the data recorded in the magnetic recording unit first by the recording / reproducing head of the first magnetic recording unit 11,
As a result of the format collation, if an instruction is issued indicating that data rewriting in the magnetic recording section is necessary, the card is once conveyed in the direction of the entrance (reverse), and then moved again from the front end of the card (from left to right in FIG. 2). When the new data is written, and the written data is read to confirm that the data has been correctly recorded (verify), the card is moved to the next step.

Referring to FIGS. 3 and 5, the type of the inserted card is identified by using a part of the magnetic recording information recorded in the prescribed format, and is instructed by the magnetic / IC card reader / writer. An example in which the written information is written on a card will be described. This first example is assumed to be the format (F) A in FIG. 5, and the writing operation proceeds according to the procedure shown in FIG. Such an example as format A is often used for a credit card issued by a domestic credit company and a card (for example, a cash card) in a format common to all banks of Japan used by banks nationwide.

First, a card is inserted into a card insertion portion of a reader / writer for both magnetic and IC cards (step 15).
1), the card reads the information recorded on the magnetic stripe by the first magnetic head by the transport roller (step 152).

Here, an example of a recording format recorded on a magnetic stripe will be described. After the timing signal starting from the edge of the magnetic stripe, the start code 112 is recorded in the first digit. In the second digit, an industry code 113 is recorded. This industry code is determined by ISO 7812 (international standard by the International Organization for Standardization), and “6” is often used. Next, a three-digit code 114 indicating the type of card is recorded in the third to fifth digits, which is a code given to the credit card company. In the next 7 to 22 digits, 16
The digit credit member code 115 is recorded. This member code is common to the embossed code formed on the surface of the card with uneven characters. Further, from the 24th digit to the 38th digit, a 15-digit name is recorded in a pseudonym code.
The four-digit expiration date 117 is recorded in the 40th to 43rd digits, but in many cases, the total is four digits, that is, two digits for the year and two digits for the month. 45
Up to the 70th digit is a “spare area” or “arbitrary area” 118 that can be used freely by credit companies. 7
An end code 119 is written in the first digit, and a check code 120 is written in the 72nd digit.

As can be seen from FIG. 3, what is recorded for each digit from the start code 112 of the first digit to the check code 120 of the 72nd digit is determined. Further, the boundary of the “contents” 111 in FIG. 3 is often a space. That is, it is possible to determine whether or not the card is a credit card by storing the number of digits where the space is recorded and checking whether or not data is recorded according to the same rules. In the example of FIG. 3, the space code is entered in four digits of 6, 23, 39, and 44. The above features are common features even if the card holder changes, and have a common format for each card. If the second digit business code is read, it can be determined that the credit card is used. As described above, even if a special area is not determined and a special flag is not set, if the regularity of the magnetic recording data is used as a criterion for determination, there is no mistake in recognition, and the determination is accurate.

Now, returning to the description of FIG.
In the format collation of No. 3, the collation format is stored in the memory of the control unit, and the characteristics of the format of the card read by the magnetic head are the formats A, B, and C.
Is matched against As a result of the verification, the card is found to be a credit card (in this case, the recording format of the credit card is A), and the card is conveyed (step 156) and sent to the second magnetic recording unit 12. here,
Since it is a credit card, nothing is recorded (step 157), and the magnetic recording unit is left as it is (the same data may be re-recorded depending on the model) (step 157).
6 and transport the card to the IC recording unit 13.

In this case, the information written on the IC chip can be set freely because it does not have a common specification. Information generated at the terminal, for example, in the case of a credit card affiliated store, point data commonly used by several affiliated stores is written into a determined file (step 1).
57). If necessary, it is recorded as “customer data 3” in the customer data recording section of the terminal of the card member store. The processed card is ejected (step 158).

Next, referring to FIGS. 4 and 5, an example in which information for specifying a recording format recorded on a magnetic stripe is read, and information specified by a reader / writer for a magnetic / IC card is written to the card. explain. For this example, format (F) A in FIG.
It is assumed that the formats B and C in B and C are used. Examples of the formats B and C are often used for an employee ID card issued by a company or a house card such as a point card issued by a store.

First, a card is inserted into a card insertion portion of a reader / writer for both magnetic and IC cards (step 15).
1), the card reads the information recorded on the magnetic stripe by the first magnetic head by the transport roller (step 152).

Here, the recording format recorded on the magnetic stripe will be described. In the magnetic stripe, after the timing signal, the first digit is the start code 1
32 are recorded. In the second digit, the industry code 133
Is recorded. This industry code is ISO7812
(International standard by the International Organization for Standardization), and “9” is often used. Next, a two-digit code 134 indicating the card type is recorded from the third digit, and a four-digit company code 135 is recorded from the next seven digits. This company code is often a convenient code. Further, a ninth to four-digit personal identification number 136 is recorded, and is used for confirmation between the terminal and the card holder. From the next thirteenth digit, a four-digit employee number 137 is recorded. In general, the employee number is generally a few-digit number, but 16 digits are assigned here. Next, the expiration date 138 is recorded from the 29th digit, which is generally two digits for the year and two digits for the month, for a total of four digits.

Next, the spare column starts from the 33rd digit.
The area from 3 to 70 digits is arbitrarily used, and information indicating the above-described processing content is recorded in the first digit of this arbitrary area, that is, the first digit 139 of the spare. As in this example, in the case of an employee ID card or a store house card, the recording position can be freely selected, and as described above, the information indicating the processing content must be set at a predetermined position. There is no standard. After any area 7
An end code 141 is recorded in the first digit, and a check code 142 is recorded in the 72nd digit.

Returning to the description of FIG. 5, in the format collation (step 153), the formats B to C are recorded in the memory unit storing the collation format, and the 33rd digit read by the magnetic head is read. (Flag)
Depending on the code, whether the inserted card is an employee ID card,
Other, for example, a credit card, or
Whether the card is a magnetic recording target card or an IC recording target card is identified. If a code indicating that the card is for magnetic recording is recorded, the card is transported according to the instruction of format B (step 156), and processed by the terminal while being compared with the customer data 3 by the magnetic recording unit 12. The new information is written (step 157). The processed card is ejected (step 158).

The employee ID card is a composite card, a magnetic recording unit,
When rewriting both data in the C recording unit, since the format is C, the magnetic recording is performed by the magnetic recording unit 12 (step 157), and then the card is returned to the step 156, and the card is newly transported to the IC recording unit 13. Then, the data processed by the terminal is written while checking with the customer data 3 (step 157). The processed card is ejected (step 158).

[0022]

As described above, according to the control method of the present invention, the subsequent treatment is determined by the information pattern read by the first magnetic information reading / recording unit of the magnetic / IC card reader / writer. Since the information is appropriately processed by the internal control program, different types of cards can be easily handled without special consideration of the operator.
