Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention provides a method for checking internally stored information such as product transaction information of an IC card used as a cash card, credit card, etc., as necessary. The present invention relates to an IC card reader that can be used.

[Conventional technology and its problems] In recent years, it has been called the cashless era, and by using cards issued by credit card companies, it has become possible to purchase products without having to take cash. ing. Conventionally, plastic cards, embossed cards, magnetic striped cards, and the like have been generally used as the above-mentioned cards, but these cards are easy to forge due to their structure, and unauthorized use has become a problem. In order to solve these problems, information cards, so-called IC cards, have recently been developed in which an IC circuit that stores the identification number, etc. is built into the card so that the identification number cannot be easily read from the outside. . This IC card has the advantage that it is difficult to forge, has excellent confidentiality, and can store a large amount of information. However, when actually conducting a transaction using an IC card as described above, it is necessary to use an IC card installed at a bank or store.
Insert the IC card into the card terminal and enter the BL identification number etc. to confirm the validity of the card and cardholder.
After that, predetermined processing operations are performed.

Here, an IC card is being considered that can store transaction data (passbook balance, purchase amount, etc.) point by point at a bank or store, etc., but in order to check the stored information, for example, You must go to your original bank or credit card company and print out the stored information. For this reason, for example, it is not easy to check how much one has spent on a credit card, or the balance on a cash card, which is very inconvenient.

(Objective of the invention 1 This invention was made in view of the above problems.

For example, when verifying the identity of a person using a card terminal installed at a store, the PIN verification unit 54 combines the PIN entered by the cardholder with a key, and the true PIN stored in advance in the verification unit 54. This is compared with the cardholder's personal identification number PIN, and if the verification unit 54 determines that the PINs match, a message indicating that the cardholder is OK is sent to the card terminal installed at the store.

Further, a data memory 55 is connected to the pass line 51. For example, when the present IC card 11 is a cash card, the data memory 55 stores deposits, withdrawals, and balances related to bank transactions. If the data is a credit card, the purchase amount and other data related to the product transaction are stored together with the date of the transaction.

Furthermore, the connection terminal 11a is connected to the pass line 51 via an interface section 56. The card circuit thus constructed from the system ROM 52 to the interface section 56 is driven by the power supply voltage VDD supplied via the interface section 43 and the connection terminal 24 of the card terminal 12.

Next, the operation of reading and displaying the transaction data stored in the data memory 55 of the IC card 11 in the actual flow side device will be explained with reference to the flowcharts shown in FIGS. 5 to 7.

Here, it is assumed that the IC card 11 is used as a credit card for commodity transactions.

First, attach the IC card 11 to the card terminal 12 and 1! When the source switch 12a is turned ON, the terminal mode is automatically set to CAL mode, and rOJ is set in the mode designation area 38 of the terminal 12. Here, in order to make the card terminal 12 function as a data reading device for the IC card 11, a key 8Il113 is required.
When the ID mode is specified by operating the CA L/ID key 16, Y is selected in step A1 in FIG.
(Yes), that is, it is determined that there has been a key operation from the CAL mode to the ID mode, and the process proceeds to step A2, where 11-: is forcibly set in the mode designation area 38, and the card terminal 12 is set to the CAL mode. Switch to ID mode. Next, the process proceeds to step A3, where it is determined whether card data such as product transaction information is already stored in the card data memory 41. If it is determined in step A3 that the data in the IC card 11 has not been read at all, the process proceeds to step A4, and the system 1IIt I[l 8I! 3
2. Supply the control signal a to the i,t card detection mechanism 40. As a result, the card detection mechanism 40 goes to step A5 to determine whether or not the IC card 11 is securely connected to the terminal 12. If the determination is Y (Yes) here, the card detection mechanism 40 goes to step A5. , the system system department 32 proceeds to step 86, and the system system department 32 executes the interface department 43.
A control signal is supplied to the As a result, the interface 8III 43 becomes activated in step △7, and all of the commodity transaction information as shown in FIG. The data is transferred to the card data memory 41, read, and stored in the card data memory 41. Here, the card terminal 12 constantly monitors whether or not there is no more card data read from the card 11 side via the interface section 43 in step 88. In this state, the process returns to step A7 to continue reading the card data. After this, in step 88 above, Y (Y
eS), ")Mari IC card 11 data memory 55
When it is determined that all the product transaction information stored in
stops supplying the III signal to the interface section 43 and releases the card data reading state.

On the other hand, it is determined that the card data is already stored in the card data memory 41 (Y (Yes) in step A3, or N (No) in step A5, that is, the card terminal 12 If it is determined that the IC card 11 is not in the connected state, the processing ends without performing the processing in the steps after that step.

When reading of the card data in the card terminal 12 is completed in the flowchart shown in FIG. 5, the process proceeds to a flowchart shown in FIG. 6 for displaying the product transaction information stored in the card data memory 41.

First, in step B1, the card terminal 12 searches the mode designation area 38, and searches the current terminal 1.
2 is in ID mode. Here Y (
Yes), that is, if it is determined that the mode area 38 is set to "1" and the mode is in the ID mode, the process proceeds to step B2, and the key input unit 13 is pressed with the numeric keypad and 5T.
Using ART key 17 or TERM key 18,
The date or period for which the card data is to be displayed is designated, and the period designation data is stored in the period memory 37. Here, for example, by the key input section 13, [60.5
] → [If you operate the key as 5TART and specify the cumulative total for May 1960, Y (Y
es), the process proceeds to step 84 and latches "1" in the memory designation flag 39 (F←1). Also, for example, if you operate the key as [60.5.27] → [5TART] and specify the cumulative total for May 27, 1960,
It is determined as Y (Yes) in step B5, and the process proceeds to step B6, where "2" is latched in the memory designation flag 39 (F←2). Furthermore, for example [60.5.271
→ [TERM] → [60.6.4] → [5TART] and specify the cumulative total from May 27, 1960 to June 4, 1960.
If it is determined (Yes), the process proceeds to step B8, where "3" is latched in the memory designation flag 39 (F←3). If no period is designated in step B2, the process proceeds to step B9, and the memory designation flag 39 is kept at "O" (F+-0).

In this case, when it is recognized that no display data is specified based on the above (F←0), the process proceeds to step BIO, and the memory specifying unit 42 specifies the R new data memory area (for example, the 8th In step B11, the system control unit 32 specifies the display system of the data corresponding to the specified memory area! Write to section III 35 is executed. As a result, the latest data in the card data memory 41, that is, the latest information on the product transaction read from the IC card 11, is displayed on the display section 14 in step 812.

On the other hand, if the memory designation flag 39 is set to "1" to "3" between steps B3 to 88, and it is confirmed that some display data has been designated in step B2, step Proceeding to B13, the individual product transaction data in the card data memory 41 is stored in the memory specifying section 4.
Month designation f- stored in the period memory 37 by 2
Only data within the period based on evening or date specified data or period specified data is retrieved and accumulated, and ST21B1
113 and 812 will be displayed. In other words, when [1] is latched in the three memory designation flags, the cumulative transaction data for May 1960 among the product transaction data stored and held in the card data memory 41 is If “2” is latched, May 2, 60
The cumulative transaction data for 7 days and, if r3J is latched, the cumulative transaction data from May 27, 1960 to June 4, 1960 are written to the display control section 35 and displayed on the display section. It will be displayed at 14.

In this way, in order to update the memory address in order to display other transaction information while the card data is displayed according to the flowchart in FIG. 6 above, proceed to the flowchart in FIG. 7 and press the key input section. 13 (+
) key 19 or (-) key 20. If, for example, the (-) key 20 is operated to display transaction information older than the currently displayed transaction information, the terminal 12 determines whether or not it is currently in the ID mode in step C1. In this step C1, Y(
Yes), that is, "1" is set in the mode area 38, and if it is determined that the mode is in the ID mode, step C
Proceeding to step 2, it is determined whether the memory designation flag 39 is set to "1". Here, Y (Yes), that is, currently,
If it is determined that the card data based on the month specification is displayed, the process proceeds to step C3, and the month specification data stored in the period memory 37 is updated in step B2 in FIG. In this case, the above month specified data is 5/60.
It will be updated from February to April 1960. On the other hand, if the determination in step C2 is negative (No), the process proceeds to step C4, where it is determined whether or not the memory designation flag 39 is set to r2J. If it is determined that the card data is currently displayed by specifying the date (Y), the process proceeds to step C5, and the date specification stored in the period memory 37 is performed in step B2 in the sixth step. Update data. In this case, the date designation data will be updated from May 27, 1960 to May 26, 1960. Furthermore, in step C4 above, N(
If the determination is No, the process proceeds to step C6, where it is determined whether or not the memory designation flag 39 is set to rOJ.

If it is determined that the latest card data is currently being displayed without any designation (Y (Yes)), the process proceeds to step C7, and the memory designation unit 42 inputs the designated address for the data memory 41 at the time. The memory area in FIG. 8 is updated in the upward direction, that is, in the upward direction. In this case, in step CB, the display control unit 35i: writes the transaction information in the card data memory 41 corresponding to the updated memory address, and in step C9, the transaction information in the card data memory 41 is written in the display control unit 35i. Information that is one data older than the transaction information displayed at B12 is now displayed.

On the other hand, between steps C2 to C5, it is confirmed that three memory designation flags are set to "1" or "2", and as described above, the month designation data in the period memory 37 is updated or the date designation is performed. If the data has been updated, the process advances to step C10, and the individual product transaction data in the card data memory 41 is stored in the period memory 37.
Only the data within the period based on the month designation data or the date designation data updated and stored in is extracted and accumulated, and is displayed through steps C8 and C9. That is, if the month specification data is updated in step C3 above, the cumulative transaction data for April 1960 is updated, and if the date specification data is updated in step C5 above, the cumulative transaction data for April 1960 is updated. The cumulative transaction data for the 26th day of each month is written into the display control section 35 and displayed on the display section 4.

If this I, for example, the (+) key 19 in the key input unit 13 is operated, the specified address for the card data memory 41 will be changed again through the processing of steps C1 to C8 or C1 to C5° CIO, C8. Updated in a timely manner, display 8i! 14, new product transaction information is again displayed in step C9.

Therefore, the card owner can easily and easily read out the stored information in the IC card 11 as appropriate.
Furthermore, it is possible to specify and confirm only the transaction information that you want to continue posting.

Next, after reading the card data as described above, when using the card terminal 12 as a normal calculator, first input the CAL/I in the key input section 13.
Operate the D key 16.

Then, in step A1 in FIG. 5 above, N
If it is determined (No), the process proceeds to step A10, where rOJ is set in the mode designation area 38 of the card terminal 12, and the function is switched to the calculator i function in the CAL mode. After this, by determining N (No) in steps B1 and C1 in FIGS. 6 and 7,
Even if the transaction information of the IC card 11 is stored in the card data memory 41, that information will not be displayed and the (+) key 19. When the (-) key 20 is operated, the routine advances to step C11, where normal addition/subtraction processing is executed, and the result of the calculation is displayed through steps C8 and C9.
