Description

[Detailed Description of the Invention] <Technical Field of the Invention> The present invention relates to various transaction systems using cards, in particular, to select only recorded data of a necessary management series from a card containing information on multiple management series. The present invention relates to a card information selection device for extracting card information.

<Background of the invention> In conventional financial transaction systems using cards, for example, magnetic cards are used for cash transactions, loan transactions, etc.
Only information related to a single management series, such as credits, is recorded. Therefore, each transaction institution issues its own magnetic card according to its management details, which requires customers to hold and use different types of cards, which is extremely inconvenient.

<Object of the invention> The present invention focuses on a transaction system that records information related to multiple management series on one card, and provides a new card that selects a necessary management series and retrieves predetermined data using this type of card. By proposing an information selection device, we aim to streamline and speed up card transactions, and to greatly improve convenience for customers.

<Structure and Effects of the Invention> In order to achieve the above object, the present invention reads recorded data related to all management series from a card containing information related to a plurality of management series using a card reading means, and corresponds to the transaction details. Information on necessary management series is selected by series selection means such as keys, and the card reading means is configured to output only read data related to the selected management series using selection processing means.

According to the present invention, at the time of a transaction, after inserting one card into a device that is a card reading means, the user can arbitrarily select the necessary management series and take out and process the specified data. , it is possible to realize the rationalization and speeding up of card transactions, and the user does not need to use multiple cards, which greatly improves the convenience of the user, achieving excellent effects that achieve the purpose of the invention.

<Description of Embodiments> FIG. 1 shows a magnetic card 1 used for carrying out the present invention, and the back of the card has information on a plurality of management series (hereinafter referred to as "first series", "second series", etc.). Information such as cash transactions, loan transactions, credits, commuter passes, etc. is independently recorded on the plurality of magnetic stripes 10A, 10B, 10C, and 10D, respectively.

FIG. 2 shows the basic configuration of the device according to the present invention, in which a card reading means 2 having a plurality of magnetic heads is shown.
reads recorded data from each of the magnetic stripes at the same time. On the other hand, the apparatus is provided with a series selection means 4, through which an operator or the like operates keys, pushbutton switches, etc. to select a necessary management series according to the content of the transaction. The selected series data is set in the storage means 5, and the selection processing means 6 causes the card reading means 2 to output only read data related to the selected management series.

FIG. 3 shows the operation flow of the above device. First, after setting the magnetic card 1 in the device, in step 71, the series selection means 4 specifies a management series, and the series data selected in step 72 is set in the storage means 5. Next, in step 73, the card reading means 2 reads all management series information from the card 1, but in the next step 74.
At this time, only the read data of the management series selected by the operation of the selection processing means 6 is output.

FIG. 4 shows a specific circuit example of the device according to the present invention.

In the illustrated example, the card reading means 2 has four magnetic heads 20A, 20B, 20C, and 20D, and each magnetic head includes a read amplifier 21, a peak detection circuit 22, a waveform shaping circuit 23, and a demodulation circuit 24.
The read data D and read clock signal CL output from each demodulation circuit 24 are sent to the selection processing means 6. Also, card reading means 2
includes a card detection section 3 consisting of a card position sensor 31 and an amplifier 32 for detecting the presence or absence of a card and the starting position of reading recorded data, and the detection output of this card detection section 3 is sent to the series selection means 4. .

The series selection means 4 includes three push button switches 40,
41, 42 and a priority encoder 43
, a decoder 44, and four AND circuits 4 to which the output of the decoder 44 and the detection output are input.
5, 46, 47, and 48, and each AND circuit outputs control signals i _A , i _B , i _C , and i _D to the selection processing means 6.

The selection processing means 6 connects each magnetic head 20 to gate circuits 60A to 60D inputting read data D whose opening and closing are controlled by control signals _iA to _iD and gate circuits 61A to 61D inputting a clock signal CL.
The output of each gate circuit 60A to 60D is connected to the input terminal IN of the shift register 64 via the OR circuit 62, and the output of each gate circuit 61A to 61D is connected to the OR circuit 63. The signals are respectively input to the clock terminals CL of the shift registers via the clock terminals CL of the shift registers.

In the series selection means 4, each pushbutton switch 41, 42, 43 has a function of self-maintaining the on/off state. It also has a function.

However, in the circuit shown in FIG. 4, when none of the pushbutton switches 40, 41, and 42 are pressed, the GS terminal of the priority encoder 42 becomes logic "H", and the AND circuit 45 outputs a logic "H" control signal. i Output _A , and other AND circuit 4
The outputs i _B , i _C , and i _D of 6, 47, and 48 are all logic "L"
becomes. As a result, only the gate circuits 60A and 61A are opened, and the read data D and the clock signal CL applied to the magnetic head 20A are input to the shift register 64, and the output terminal of the shift register 64 outputs 8-bit data.

Also, when the push button switch 40 is pressed,
The AND circuit 46 outputs a logic "H" control signal _iB to open the gate circuits 60A and 60B, and similarly, in response to the push button switch 41, the gate circuits 60C and 61C and the push button switch 42 are pushed. , gate circuits 60D and 61D are opened, respectively, and read data D and clock signal CL related to the corresponding magnetic heads 20B to 20D are sent to shift register 64.
