DETAILED DESCRIPTION OF THE INVENTION Technical Field of the Invention The present invention relates to a method for determining the validity or invalidity of a cash card, and in particular is used in automatic teller machines, automatic teller machines, etc., and is used to determine the validity or invalidity of a cash card on which a secret number is recorded This invention relates to a valid/invalid determination method that determines whether

Description of the Prior Art In transaction processing devices such as automatic teller machines and automatic teller machines in banks, cash cards with secret numbers recorded thereon are often used to deposit and withdraw cash.

If such a Kitotshu card is stolen or lost, the cash card must be reissued. At this time, it is necessary to change the secret number conventionally recorded in the cash node to another number.

However, since the secret number of the stolen or lost ATM card is different from the reissued secret number, the user may accidentally enter the secret number of the lost Kiretshu card when using the reissued ATM card. There is a risk that it will become a problem.

This was particularly noticeable among children and the elderly who were not good at memorizing secret numbers. Therefore, it is possible to reissue a cash card with the same secret number recorded as the lost cash card, but in this case, the lost cash card is misused. j3 There was a problem with that.

Purpose of the InventionIn addition, the main purpose of the present invention is to avoid the risk of using the same secret number when reissuing a lost ATM card, and also to prevent it from being misused. We will present a method for determining validity and invalidity using the TSUSH card.
W.

Development and Effects of the Invention If this invention is not applicable, the cash card can be reissued by inserting a personal record area on the cash card to store the secret number and check flag. Updated check flags and updated 。〕tsuku-7
When registering the lag and determining the invalidity of Kitotshu/J--do, the secret number and check flag recorded in the recording area of Cage-1 Car 1~ are highlighted. The validity or invalidity of a cash card is determined by determining whether or not the secret number and check flag match.

Therefore, if you use this invention, it will be lost or stolen! The secret number recorded on your cash card and f
Even if a cash card with the same secret number recorded is reissued, a check flag is used to determine whether it is valid or invalid, so there is no risk of it being misused.
ShiDI also does not require the user to memorize a new secret number, so it can be used very effectively even by young Yarmians who have poor memorization skills.

The present invention will be explained in more detail below along with examples not shown in the drawings.

DESCRIPTION OF EMBODIMENTS FIG. 1 is a schematic block diagram of a transaction processing device to which the present invention is applied. First, the configuration will be explained with reference to No. 1N4. CPU 1 performs a deposit operation and a payment operation based on a program stored in ROM 4.
, to perform control.

This CPU 1 includes a keyboard 2, a card reader 3, and an RO.
M4, RAM 5, display 6, printer 7, and coin dispenser 8 are connected. The keyboard 2 is operated by the user when inputting a secret number. The card league 3 is for reading the secret number recorded on the keyboard and the check flag which is a feature of this invention. The RAM 5 stores data input from the keyboard 2, data calculated by Cl) U1, and the like. The display 6 displays data such as the amount of cash deposited or the amount paid, and the printer 7 prints the same data on the cash register (-).The coin dispenser 8 displays the amount of money to be paid. It is later to release the .

FIG. 4 is a flowchart for explaining the present invention in detail.

Next, the specific operation of the present invention will be explained with reference to FIGS. 1 to 4. As shown in FIG. 3, the magnetic stripe 10 of the cash card 9 is provided with an area for storing and storing the check flags 4-1. , 0000 is recorded in this area 12. and,(
When the security card 9 is stolen or lost and is reissued, 0001 is recorded as the boonick flag as shown in FIG. b) Check flag 0 as shown in
Check flags that are updated sequentially such as O10 are recorded. The updated f-errata flag is then registered in the host computer (f in the figure). In this way, since one nick flag is composed of one bin 1~, it is possible to reissue the cache/IJ-card 9 15 times. If you want to increase the number of times, increase the number of bits in area '12. +Sur good.

l2) When processing a transaction using the Noko Cash Card 9, the key V.
Insert the Tush card 9 into the card reader 3 shown in FIG. The card reader 3 reads the V) secret number and check flag recorded on the cash card 9 and
Enter i. At the same time, the user sweeps the keyboard 2 and inputs the secret code. The CPU 1 sends the secret number read by the card reader 3 and the check flag to the post computer. The host computer determines whether or not the secret number and block flag are registered. , if it is registered, please reply to CP LJ 1 and send it to Or' U N tj card reader 3.
It is determined whether or not the secret number read from the keyboard matches the secret number input from the keyboard 3. ~ Then, it is determined that the Kiki Tush card 9 is valid, and the necessary coins are discharged from the Chinese coin discharge transport 8.

However, if the host computer determines that the given secret number and check flag do not match the registered secret number and check flag, the CPU
1, the CPU 1 reads the card 9 with the card reader 3 and imports the card 9 into the card reader 3.
