Description

[Detailed Description of the Invention] The present invention relates to an ID card (personal identification card) used in a cashless system, etc., and particularly to an I[) card that can prevent double use when the ID card is lost.

In cashless systems, ID cards are used to provide meals at the company cafeteria, for example.

In this case, the ID card has a mark unique to the user.

Numbers, etc. are written on the ID card, and by reading this ID card with a reader device, one meal is provided to the user with one reading operation, and the number of times of use is determined by the address unique to the ID card in the reader device. It will be remembered in

In such a system, if a user loses their ID card and a new ID card is reissued to that user, the lost LJ'c ID card may be misused by another user. The disadvantage is that it is difficult to distinguish even if

On the other hand, if you try to prevent misuse by changing the data contents of the card at the time of reissuance, you will have to compare all the data on the ID card to see if every card used is the lost one. In this case, when comparing the number of reissued cards and first edition cards, the number of first edition cards is much higher, so even the users of the first edition cards have to spend a lot of time to identify the number of reissued cards. It has the disadvantage of being bulky.

In addition, when an ID card with a new registration number is created for the lost person, the corresponding system stores the new registration number data and also stores the registration number data of the lost card. You must take steps to prevent the misuse of your cards.

Therefore, the number of the lost card naturally becomes a so-called vacant address, which has the disadvantage that the memory capacity of the system for storing this data further increases.

Therefore, this invention was developed in view of the above-mentioned circumstances.The card itself has a reissue bit separate from the personal number bit, and when reissuing, only the reissue bit is changed, so that if the card is lost, However, the purpose of the present invention is to provide an ID card that can be checked to prevent it from being misused, and that does not require any changes in administrative processing before and after reissuance.

An embodiment of the present invention will be described below with reference to the drawings.

First, the ID card according to the present invention is configured, for example, in a data form as shown in FIG.

That is, the ID card ID shown in the same figure has an individual number part IDF and a reissue part REF, and has an individual number part IDF+plus one digit 4.
Displayed as a 4-digit decimal number consisting of bits, reissue part R
EF is displayed as a 1-digit decimal number.

According to the ID card ID of such data form 1
This means that 10,000 people can be identified, and ID cards can be reissued 10 times for each individual.

This one data is set as follows.

If the user's personal number is 2654, the ID card ID
For example, by magnetically etc., 2654 is added to 3 in the individual number part IDF of
When issued for the first time, the reissue unit REF is set to 0 and the five-digit number 02654 is stored in the ID card ID.

Therefore, when reissuing an ID card ID if the user has lost it, the data in the individual number section IDF is set to 2654, the same as when it was first issued, and only the data in the reissue section REF is set to 0.
Rewrite it as 1.

Furthermore, when reissuing, the data in the reissue section REF is rewritten to 2 and the personal number section remains unchanged.

As described above, the ID card ID can be reissued 10 times.

Thus, the ID card configured as described above can be applied to a system as shown in FIG. 2 to check for card loss.

That is, the user inputs the ID card ID into the ID card reader CR.
The contents of the ID card are read by the card reader CR and the read contents are input to the collation circuit CC.

On the other hand, the data of the lost ID card ID is set in the verification setting device C8, and the data of the ID card ID transferred to the verification circuit CC and the data in the verification setting device C8 are set in the verification circuit CC. If the two match, the ID card inserted into the card reader CR is a lost ID card, and an alarm signal will be sent from the output terminal T to the row section.

Also, if the two data compared by the verification circuit CC do not match, this ID card is genuine.
A normal signal is sent from the output terminal T to a control section (not shown), and, for example, one meal is provided to the user and the number of times of use is stored.

Next, the specific circuit configuration of the verification setting device C8 and the verification circuit CC will be explained with reference to FIG.

Here, LCD i, LCD2... are digital switches DG 11 s DG in the dust card data setting section.
12...DG, and in one embodiment, 4 x 5 = 20 notation inputs are provided on LCD1, LCD2... to manually input 5 decimal digits using BCD. .

The first ID card issued to an individual user, for example, R026.
If the ID card containing the data of 54J is lost, this data 02654 is stored in the setting section LCDI (0000) to prevent it from being misused by another user.

(0010), (0110), (0101)s(010
0).

In this case, setting "0" is done by opening the digital switch DG corresponding to that bit, and setting "1" is done by closing the digital switch corresponding to that bit.

Further, if the reissued ID card is lost again, data r12654J at the time of reissue is set in the setting section LCD2.

Therefore, setting section LCDs are prepared for the number of ID cards that have been lost.

Also -NG 115NG21... -NG nl 412
It is a human-powered NAND gate, and one input terminal receives the outputs of each digital switch of the setting section LCD, and the other input terminal receives the scan signal terminals t1. t2・-
A scan signal, which will be described later, is input manually for each setting section.

When the digital switch DG is closed, the NAND gate NG receives a signal of "0", and when it is open, the signal is 1
``A level signal is given.

l0GI, l0G2...■OGn is two-person exclusive OR
gate, and one input terminal has each setting section LCD1. L
The outputs of the corresponding NAND gates of CDz, .

NAG is a multi-input negative logic NAND gate to which the output of the exclusive OR gate (IOC) is input.

This gate NAG produces an output of O'' only when the outputs of the exclusive OR gate IOG are all 1''.

Next, the operation of the above circuit configuration will be described.

now. Assume that an individual user loses an ID card storing data r02654J and the ID card storing data r12654J is reissued.

In this case, the data r02654j is set in the setting section LCDI by a digital switch.

Then, when the user inserts his/her ID card into the card reader CR, the data is read by the card reader CR, and data r12654J is sent to the verification circuit CC, and the other of the exclusive OR gates 10G1, 10G2, etc. is given to the input terminal of

On the other hand, data r02645J of the lost ID card is set in the setting section LCD1, and when the ID card is inserted into the card reader CR, a scan signal "1" from a timing circuit (not shown) is first sent to the scan signal terminal t1. given to NAND gate NG115NG12...
・Opens and digital switches DGll, DG12...
・The data set in the NAND gate NG 11
, NG12..., each OR gate ■OG1.
■Given to one input terminal of OG2...

Here, when comparing the data given by all the card readers CR and the data set in the setting part LCD1, the reissue parts are each 10, which does not match, so this part is input to the OR gate ■OG The exclusive OR is established and the output is NO.

Therefore, the output of the NAND gate NAG in this case is 1'', and in this case, the control unit (not shown) controls the personal number section I in the data of the ID card read by the card reader CR.
The number of times the DF data r2654J has been used is stored, and the user is provided with a meal.

By the way, when the supposedly lost ID card with the data "02654" stored in the card reader CR is inserted, it is read out by the data read by the card reader CR and the "1" signal given to the scan signal terminal t1. The data set in the setting section LCDI (OR game) all match at the input terminal of the IOC, and the
Since all outputs of Rage-IOC become 1", N
NAND logic is established in AND gate NAG, and its output becomes "NO".

If the output of the NAND gate NAG becomes 0'', an alarm device (not shown) sends an alarm signal to the outside because the lost card has been used after the ID card is reissued.

Furthermore, if an individual user loses their ID card and it is reissued for the second time, this ID card will contain data r226.
54J is memorized, and the lost data r1 is stored in the setting section LCD 2.
2654j is set.

Now, when an ID card in which data r02654J or r12654J is stored is used, the data of setting section LCD1 or terminal t1 is read out when the scan signal terminal t1 given from a timing circuit (not shown) becomes 1''. The setting section LCD2 is read out by the scan signal "1" given to the terminal t2 after becoming 0".
When any of the data read by the card reader CR matches, the output of the NAND gate NAG becomes 0'' and an alarm signal is sent to the outside (to the administrator).

In this case, when the scan signal "1" is applied to the terminal t1, the terminal t2 is "NO", so the outputs of the NAND gates NG 21, NG 22, etc. are all 1.
", and only the data of the setting section LCD1 is sent to the OR gate ■OR without being affected by the data of the setting section LCD2, and similarly, the scan signal " is sent to the terminal t2.
1'' is applied, the terminal t1 is O'', and only the data in the setting section LCD2 is read out without being affected by anything else.

In this way, the setting section LC is set for the number of ID cards lost.
By providing D, if a lost ID card is used after the ID card is reissued, there is no need to check all ID cards, and an alarm signal is immediately sent to the outside. Processing is carried out only by the individual number section IDF, which does not change even after reissuance, so it can be done without any new changes in case of administrative processing, etc.

As mentioned above, according to the present invention, by providing a new reissue section in the ID card itself in addition to the personal number section, it is very easy to check even if the ID card is reissued due to loss etc. Become.

In addition, no changes are required in subsequent administrative procedures, etc.I
I can provide a D card.

In the present invention, the ID card itself has a personal number section and a reissue section, and the personal number section is a number unique to the individual, and even if the card is lost and a new card is obtained, it will remain the same number.

Therefore, there is no need to copy the data corresponding to this number.

Furthermore, the difference between the lost card and the new card can be reliably determined by the reissue number.

In other words, only the number of issuance data of the ID card reissuing unit is changed, and the verification system side does not need to be changed at all.

Therefore, even if there is a lost person, there will be no vacant address, and therefore the memory can be used effectively without increasing the memory capacity.

In the above embodiment, an example was explained in which the verification setting device C8 was configured by a digital switch DG, but it may also be configured by, for example, a core memory or the like.

That is, as shown in FIG. 4, the data of the lost ID card is stored in a memo UM having the number of bits required to store the data of the lost ID card by a write command via the data register DR1 and the address register AR. When the ID card is inserted into the card reader CR, the data of the lost ID card is transferred from the memory M to the collation circuit CC via the data register DR2 by the address advance and read signal given to the address register AR. The data may be compared with the data read by the card reader CR.

Other vehicle designs can be modified and implemented without changing the gist of the invention.
