[0002]
[Prior art]
In magnetic card processing machines that process magnetic information of magnetic cards used for station services, distribution, etc., there is a strong need to be able to easily and stably process magnetic information, but third parties can easily read and decode recorded information. A method that cannot be tampered with is desired.
[0003]
Hitherto, a method has been devised in which the recording magnetic layer is formed into a multilayer structure using materials having different characteristics of magnetic properties. However, since the characteristics of the magnetic material are not significantly changed, they have not had a sufficient protective ability.

However, in order to stably record independent information on the high-retention recording magnetic material and the low-retention recording magnetic material, the difference in the coercive force is small at present, causing mutual interference or essentially rewriting. Has the disadvantage that it is possible. That is, there is a possibility that the magnetic card is forged or falsified.

[0017]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 and FIG. 2 show a magnetic card coated with a magnetic material such as a commuter pass, a ticket, a prepaid card, etc. used for transportation, distribution, and the like. Here, a prepaid card is described as an example of a magnetic card having a price function.
[0018]
That is, in the magnetic card 1, as shown in FIG. 1, a magnetic layer 3 in which a high-retention recording magnetic material and another magnetic material are mixed is provided on a base layer 2. The base layer 2 is made of PET (polyethylene terephthalate) or paper.
[0019]
The magnetic layer 3 has a high holding recording magnetic material made of barium ferrite and has a low coercive force initially set by a special treatment, but once exposed to a magnetic field, the coercive force increases significantly. S magnetic material having characteristics (difficult to record with a conventional magnetic head) ｛For example,MnBi(Manganese bismuth) is applied to the base layer 2 by mixing a magnetic powder, such as magnetic powder, whose retentivity greatly changes between an initial state and after exposure to a magnetic field.
[0020]
The magnetic layer 3 of the magnetic card 1 has two tracks, a one-time recording track (issue information track) 4 and a read / write track (use track) 5, as shown in FIG.
[0021]
The one-time recording track (issue information track) 4 records issuance information at the time of issuance, that is, in the initial state, so that the S magnetic body 4a records the recorded content with a remarkably high coercive force. Reference numeral 4b denotes a track for holding the recorded content at a high level, and it is possible to read the recording magnetic flux recorded on both of the magnetic bodies 4a and 4b in reading.
[0022]
In the one-time recording track 4, once the magnetic field is exposed, the S magnetic body 4 a changes to a remarkably high holding force, and it is not possible to perform recording again on the S magnetic body 4 a, and the basic issue of the magnetic card 1 is performed. Information recorded only at the time of issuance of information or the like (information that is not rewritten when recorded at the time of issuance) is recorded, and protection information such as an encryption key is also recorded. As a result, rewriting cannot be performed on the one-time recording track 4, so that recording that is difficult to falsify can be performed.
[0023]
The basic issuance information includes information indicating the range of the amount of money, the issuing organization, and the applicable system in issuance, and the issue number as $ D of the card.
At the time of issuance, that is, in the initial state, the read / write track (used track) 5 is first erased (application of a magnetic field) by a DC magnetic field, so that the S magnetic body 5a has a remarkably high coercive force and magnetic rewrite. And the high-retention recording magnetic material 5b is erased from the high-retention recording information, and no information is recorded. If the high holding recording is further performed, the S magnetic body 5a does not contribute to the recording because it has changed to a remarkably high holding force, but the high holding recording magnetic body 5b can record, read, and rewrite as usual.
[0024]
The read / write track (use track) 5 is used as a recording area for sequential information such as a conventional record for each use (transaction such as consideration) and a balance record (charging information). That is, as information generated for each use, a usage record and a balance information such as a usage amount, a code indicating purchased property information, a date and time of processing, a processed place, and a balance are recorded. This track is a track that must be rewritten because recording and reading are repeated each time it is used.
[0025]
As described above, the magnetic card 1 having the same magnetic material structure can be switched to applications having different properties by the first processing, and thereby the falsification can be prevented.
[0026]
FIG. 3 is a sectional view showing a configuration of a main part of the magnetic card issuing machine.
That is, a stacker 12 in which a plurality of magnetic cards 1 before issuance are stored is provided on the left side of the main body 11 in the figure. The magnetic cards 1 of the stacker 12 are taken out one by one by a take-out roller 13 and are conveyed by a conveyance path 14. The transport path 14 is provided with transport rollers 15 for transporting the magnetic card 1. The transport path 14 includes write heads 16 and 17 for recording information on the magnetic card 1 taken out by the take-out roller 13 and erasing the information by a DC magnetic field, and a read head for reading information recorded on the magnetic card 1. 18 are provided sequentially. The magnetic card 1 read by the reading head 18 is issued from an issuing port 19 provided at the end of the transport path 14.
[0027]
The magnetic card 1 is transported on the transport path 14 in the transport direction x shown in FIG.
The write heads 16 and 17 can separately apply a recording or erasing magnetic field to the one-time recording track 4 and the read / write track 5, respectively.
[0028]
The read head 18 can separately read the one-time recording track 4 and the read / write track 5.
FIG. 4 is a block diagram showing a configuration of a control circuit of the magnetic card issuing machine.
[0029]
That is, the control unit 21 controls the entire magnetic card issuing machine. The control unit 21 includes an operation panel 22 for inputting issuance contents and the like, a driver 24 for driving a transport mechanism 23 by the take-out roller 13 and the transport roller 15, a driver 25 for driving the write head 16, a write head 17 And a reading circuit 27 for determining the contents read by the reading head 18 are connected.
[0030]
Next, the issuing process (1) of the magnetic card 1 will be described with reference to a flowchart shown in FIG.
That is, the user designates the amount of money to be issued, the issuing organization, the range of the applicable system, and the issue number as the conditions for issuing the card by using the operation panel 22, and inputs a start key (not shown) (ST1).
[0031]
Then, the control unit 21 rotates the take-out roller 13 and the transport rollers 15,... By driving the transport mechanism 23 by the driver 24. Thereby, the magnetic card 1 stored in the stacker 12 is taken out by the take-out roller 13 and is conveyed by the conveyance path 14 (ST2).
[0032]
Next, the control unit 21 transmits information indicating the amount of money, the issuing organization, and the range of the applicable system in issuance as basic issuance information corresponding to the issuance condition of the card specified by the operation panel 22, and encodes the issue number as $ D of the card. Is supplied to the write head 16 via the driver 25 (ST3).
[0033]
As a result, the write head 16 uses the S magnetic body 4a and the high-holding recording magnetic body 4b of the one-time recording track 4 to indicate the amount of money, the issuing institution, and the applicable system range in the issuance as basic issuance information. Is issued, a DC erasing magnetic field is applied to the read / write track 5, and the track is erased (ST4).
[0034]
As a result, the basic issue information is recorded on the S-magnetic body 4a of the one-time recording track 4 with a remarkably high coercive force, and the S-magnetic body 5a of the read / write track 5 enters an erase state with a remarkably high coercive force.
[0035]
At this time, the control unit 21 stores the basic issue information in an internal memory (not shown).
Next, the controller 21 supplies the write head 17 via the driver 26 with the DC erasing signal and the encoding information of the format data as the information of the initial value (ST5).
[0036]
As a result, a DC erasing magnetic field is applied to the one-time recording track 4 by the write head 17, the basic issue information recorded on the high-holding recording magnetic material 4b is erased, and the initial value information, for example, is written to the read / write track 5. Format data is recorded (ST6).
[0037]
As a result, the basic issue information is recorded on the S magnetic body 4a of the one-time recording track 4 with a remarkably high holding force, the high holding recording magnetic body 4b is erased, and the S magnetic body 5a of the read / write track 5 is markedly remarkable. In the erase state with high holding power, format data is recorded on the high holding recording magnetic body 5b.
[0038]
Further, the one-time recording track 4 and the read / write track 5 are read by the read head 18, and the read contents are supplied to the control unit 21 via the read circuit 27 (ST7).
[0039]
Thereby, the control unit 21 compares the read content from the one-time recording track 4 with the recorded basic issue information stored in the internal memory, and compares the read content from the read / write track 5. The validity of the magnetic card 1 is confirmed based on whether the format data is correctly recorded according to the content (ST8).
[0040]
As a result, when the validity of the magnetic card 1 is confirmed, the control unit 21 guides the issuance of a correct card through the operation panel 22 and issues the magnetic card 1 from the issuing port 19 (ST9).
[0041]
If the validity of the magnetic card 1 is not confirmed in step 8, the control unit 21 guides the card issuing abnormality through the operation panel 22 and ejects the magnetic card 1 from the issuing port 19 (ST10). .
[0042]
Further, the magnetic card 1 in which the issuance is abnormal may be collected in a collection box (not shown).
In the case of this issuance process (1), the read output of information recorded on the one-time recording track 4 (the S magnetic body 4a thereof) and the information is recorded on the read / write track 5 (the high holding recording magnetic body 5b thereof). The read output of the information is at the same level.
[0043]
At this time, the magnetic layer 3 is applied at a component ratio such that the outputs of the high-retention recording magnetic material and the S magnetic material of each track are the same.
Next, the issuing process (2) of the magnetic card 1 will be described with reference to the flowchart shown in FIG.
[0044]
That is, the user designates the amount of money to be issued, the issuing institution, the range of the applicable system, and the issue number as the card issuing conditions using the operation panel 22, and inputs a start key (not shown) (ST11).
[0045]
Then, the control unit 21 rotates the take-out roller 13 and the transport rollers 15,... By driving the transport mechanism 23 by the driver 24. Thereby, the magnetic card 1 stored in the stacker 12 is taken out by the take-out roller 13 and is conveyed by the conveyance path 14 (ST12).
[0046]
Next, the control unit 21 transmits information indicating the amount of money, the issuing organization, and the range of the applicable system in issuance as basic issuance information corresponding to the issuance condition of the card specified by the operation panel 22, and encodes the issue number as $ D of the card. Is supplied to the write head 16 via the driver 25 (ST13).
[0047]
As a result, the write head 16 uses the S magnetic body 4a and the high-holding recording magnetic body 4b of the one-time recording track 4 to indicate the amount of money, the issuing institution, and the applicable system range in the issuance as basic issuance information. Is issued, and a DC erasing magnetic field is applied to the read / write track 5 to erase the track (ST14).
[0048]
As a result, the basic issue information is recorded on the S-magnetic body 4a of the one-time recording track 4 with a remarkably high coercive force, and the S-magnetic body 5a of the read / write track 5 enters an erase state with a remarkably high coercive force.
[0049]
Next, the control unit 21 supplies the encoding head of the format data as the information of the initial value to the writing head 17 via the driver 26 (ST15).
As a result, information of the initial value, for example, format data is recorded on the read / write track 5 by the write head 17 (ST16).
[0050]
As a result, the basic issue information is recorded on the S magnetic body 4a of the one-time recording track 4 with extremely high coercive force, and the basic issue information is also recorded on the high magnetic recording body 4b. The magnetic material 5a is in an erasing state with a remarkably high coercive force, and format data is recorded on the high-retention recording magnetic material 5b.
[0051]
Further, the one-time recording track 4 and the read / write track 5 are read by the read head 18, and the read contents are supplied to the control unit 21 via the read circuit 27 (ST17).
[0052]
As a result, the control unit 21 compares whether the content read from the one-time recording track 4 matches the recorded basic issue information, and the format data is correctly recorded based on the content read from the read / write track 5. Then, the validity of the magnetic card 1 is confirmed (ST18).
[0053]
As a result, when the validity of the magnetic card 1 is confirmed, the control unit 21 guides the issuance of a correct card through the operation panel 22 and issues the magnetic card 1 from the issuing port 19 (ST19).
[0054]
If the validity of the magnetic card 1 is not confirmed in step 18, the control unit 21 guides the card issuing abnormality through the operation panel 22 and ejects the magnetic card 1 from the issuing port 19 (ST20). .
[0055]
In the case of this issuance processing (2), the read output of the information recorded on the (one-time recording track 4 (the S magnetic body 4a and the high holding recording magnetic body 5b)) is changed to the (high holding recording magnetic The read output of the information recorded on the body 5b) is higher by the read output of the S magnetic body 4a.
[0056]
That is, the issuance process is completed with the output level difference between the one-time recording track 4 and the read / write track 5.
FIG. 7 is a sectional view showing a configuration of a main part of the magnetic card processing machine.
[0057]
That is, an insertion slot 32 into which the magnetic card 1 is inserted is provided on the right side in the figure of the main body 31. The magnetic card 1 inserted into the insertion slot 32 is transported on a transport path 34 by transport rollers 33,. The magnetic card 1 taken into the main body 31 is transported on the transport path 34 by the reverse rotation of the transport rollers 33,... And is discharged from the insertion slot 32. The transport path 34 is provided with a read head 35 for reading information on the magnetic card 1 and a write head 36 for recording information on the magnetic card 1. The read head 35 reads information from the magnetic card 1 inserted through the insertion slot 32 and reads the recorded information from the magnetic card 1 on which information is recorded by the write head 36. The write head 36 is for recording information on the magnetic card 1 being conveyed and for applying an erasing magnetic field.
[0058]
The magnetic card 1 is transported on the transport path 34 in the transport direction shown in FIG.
The write head 36 can separately apply a recording or erasing magnetic field to the one-time recording track 4 and the read / write track 5.
[0059]
The read head 35 can separately read the one-time recording track 4 and the read / write track 5.
FIG. 8 is a block diagram showing a configuration of a control circuit of the magnetic card processor.
[0060]
That is, the control unit 41 controls the entire magnetic card processing machine. The control unit 41 includes an operation panel 42 for inputting processing details, a driver 44 for driving a transport mechanism 43 by transport rollers 33,..., A read circuit 45 for determining the content read by the read head 35, and a write head 36. Is connected.
[0061]
Next, the use process of the magnetic card 1 issued in the issue process (1) will be described with reference to the flowchart shown in FIG.
That is, when the insertion of the magnetic card 1 from the insertion slot 32 is detected by a detector (not shown) (ST31), the control unit 41 drives the transport mechanism 43 by the driver 44 to correct the transport rollers 33,. Rotate in the direction. Thereby, the magnetic card 1 inserted from the insertion slot 32 is transported by the transport path 34 (ST32).
[0062]
Next, reading of the magnetic card 1 is performed by the reading head 35. That is, information indicating the amount of money, the issuing organization, and the range of the applicable system in the issuance as the basic issuance information recorded on the (one-time recording track 4) (the S magnetic body 4a thereof). The usage record such as the balance recorded on the (high-retention recording magnetic body 5b) of the write track 5 is read, and the read contents are supplied to the control unit 41 via the reading circuit 45 (ST33).
[0063]
The control unit 41 determines the validity of the read basic issuance information (ST34), and if determined to be valid, calculates the remaining amount as a new usage record by subtracting the fee for the current process from the remaining amount (ST35). At this time, the fee for the current process is specified by the operation panel 42, for example.
[0064]
Next, the control unit 41 supplies the direct current erase signal and the remaining encode information as a new use record to the write head 36 via the driver 46 (ST36).
As a result, a DC erasing magnetic field is applied to the one-time recording track 4 by the write head 36, and the remaining amount as a new use record is recorded in the read / write track 5 (ST37).
[0065]
Thereafter, the control unit 41 drives the transport mechanism 43 by the driver 44 to rotate the transport rollers 33 in the opposite direction. As a result, the magnetic card 1 on which the writing is performed by the writing head 36 is conveyed to the insertion port 32 side by the conveying path 34 (ST38).
[0066]
Next, the one-time recording track 4 and the read / write track 5 are read by the read head 35, and the read contents are supplied to the control unit 41 via the read circuit 45 (ST39).
[0067]
Thereby, the control unit 41 compares the contents read from the one-time recording track 4 with the basic issue information read in step 33, and if it is determined that there is no change due to erasure due to the match (ST40), further reads / writes. The legitimacy of the magnetic card 1 is determined based on the coincidence of the read content of the track 5 with the recorded new use record (ST41), normal processing is guided by the operation panel 42, and the magnetic card 1 is ejected from the insertion slot 32. (ST42).
[0068]
If the validity of the read basic issuance information is not determined in step 34, if it is determined in step 40 that there is a change due to erasure, if the validity of the magnetic card 1 is not determined in step 42, the control unit 41 guides through the operation panel 22 that the accepted magnetic card 1 is an abnormal ticket, and ejects the magnetic card 1 from the insertion slot 32 (ST43).
[0069]
As described above, by applying a DC erasing magnetic field to the one-time recording track 4, it is determined whether the issuance information recorded on the one-time recording track 4 has been erased or not, and whether or not the information has been forged. It is something to check.
[0070]
Next, the use process of the magnetic card 1 issued in the issue process (2) will be described with reference to the flowchart shown in FIG.
That is, when the insertion of the magnetic card 1 from the insertion slot 32 is detected by a detector (not shown) (ST51), the control unit 41 drives the transport mechanism 43 by the driver 44 to correct the transport rollers 33,. Rotate in the direction. Thereby, the magnetic card 1 inserted from the insertion slot 32 is transported by the transport path 34 (ST52).
[0071]
Next, reading of the magnetic card 1 is performed by the reading head 35. That is, information representing the amount of money, the issuing organization, and the range of the applicable system in the issuance as the basic issuance information recorded on the (one-time recording track 4 (the S magnetic body 4a, the high holding recording magnetic body 4b)), Reading of the issue number and reading of the actual usage such as the balance recorded on the read / write track 5 (the high holding recording magnetic material 5b thereof) are performed, and the read contents are supplied to the control unit 41 via the reading circuit 45. Is performed (ST53).
[0072]
The control unit 41 determines the validity of the read basic issuance information (ST54), and when it is determined to be valid, the read level from the one-time recording track 4 is the read / write track 5 (the high holding recording magnetic material 5b). It is determined whether or not the reading level is higher than that of the S magnetic body 4a by the S magnetic body 4a (ST55). The balance as a new usage record obtained by subtracting from the balance is calculated (ST56). At this time, the fee for the current process is specified by the operation panel 42, for example.
[0073]
Next, the control unit 41 supplies the direct current erase signal and the encoding information of the remaining amount as a new use record to the write head 36 via the driver 46 (ST57).
Thus, the remaining amount as a new usage record is recorded on the read / write track 5 by the write head 36 (ST58).
[0074]
Thereafter, the control unit 41 drives the transport mechanism 43 by the driver 44 to rotate the transport rollers 33 in the opposite direction. Thereby, the magnetic card 1 on which the writing is performed by the writing head 36 is conveyed to the insertion port 32 side by the conveying path 34 (ST59).
[0075]
Then, the read / write track 5 is read by the read head 35, and the read contents are supplied to the control unit 41 via the read circuit 45 (ST60). Thus, the control unit 41 determines the validity of the magnetic card 1 based on the coincidence of the read contents of the read / write track 5 with the recorded new use record (ST61), and guides the normal processing through the operation panel 42, and Then, the magnetic card 1 is ejected from the insertion slot 32 (ST62).
[0076]
If the validity of the read basic issuance information is not determined in step 54, if the read level is not large by the S magnetic body 4 a in step 55, the validity of the magnetic card 1 is determined in step 61. Is not determined, the control unit 41 guides the received magnetic card 1 to the effect that the received magnetic card 1 is an abnormal ticket through the operation panel 22 and ejects the magnetic card 1 from the insertion slot 32 (ST63).
[0077]
As described above, depending on whether or not the read level of the one-time recording track 4 is higher than the read level from the read / write track 5 (the high-retention recording magnetic body 5b) by the S magnetic body 4a. This is to check if it is counterfeit. Also, by checking this decrease, it is possible to know the possibility that a forgery attack has been made.
[0078]
Also, by utilizing the features of the one-time recording track 4 and linking it to an issue number, an encryption key, and the like, important data is scrambled by a functional formula, and this is recorded on the read / write track 5 as well. Thus, a relationship between the one-time recording information and the rewriting recording information can be created to prevent tampering.
[0079]
Further, in the above-described embodiment, the case where the magnetic layer formed by mixing the high retention recording magnetic material and the S magnetic material is applied over the entire surface of the magnetic card on the base layer has been described. The present invention is not limited to this, and as shown in FIG. 11, a configuration may be adopted in which the high-retention recording magnetic material 51 and the S magnetic material 52 are applied in a two-layer structure over the entire surface of the magnetic card 1 on the base layer 2.
[0080]
In this case, the issuing process shown in FIGS. 5 and 6 and the use process shown in FIGS. 9 and 10 can be performed similarly.
As shown in FIG. 12, in the magnetic card, the S magnetic material 53 is applied only to the portion of the one-time recording track 4 on the base layer 2 and the high holding recording magnetic material is applied only to the portion of the read / write track 5. 54 may be applied.
[0081]
The issuing process of the magnetic card 1 in this case will be described with reference to the control circuit of the magnetic card issuing machine shown in FIG. 4 and the flowchart shown in FIG.
That is, the user designates the amount of money to be issued, the issuing organization, the range of the applicable system, and the issue number as the card issuing conditions using the operation panel 22, and inputs a start key (not shown) (ST71).
[0082]
Then, the control unit 21 rotates the take-out roller 13 and the transport rollers 15,... By driving the transport mechanism 23 by the driver 24. Thereby, the magnetic card 1 stored in the stacker 12 is taken out by the take-out roller 13 and is conveyed by the conveyance path 14 (ST72).
[0083]
Next, the control unit 21 transmits information indicating the amount of money, the issuing organization, and the range of the applicable system in issuance as basic issuance information corresponding to the issuance condition of the card specified by the operation panel 22, and encodes the issue number as $ D of the card. Is supplied to the write head 16 via the driver 25 (ST73).
[0084]
As a result, the write head 16 records information indicating the range of the amount of money, the issuing organization, and the applicable system, and the issue number as $ D of the card on the one-time recording track 4 (ST74).
[0085]
As a result, the basic issue information is recorded on the one-time recording track 4 with extremely high holding power.
Next, the control section 21 supplies the encoding information of the format data as the information of the initial value to the writing head 17 via the driver 26 (ST75).
[0086]
Thereby, information of the initial value, for example, format data is recorded on the read / write track 5 by the write head 17 (ST76).
As a result, the format data is recorded on the read / write track 5.
[0087]
Further, the one-time recording track 4 and the read / write track 5 are read by the read head 18, and the read contents are supplied to the control unit 21 via the read circuit 27 (ST77).
[0088]
As a result, the control unit 21 compares whether the content read from the one-time recording track 4 matches the recorded basic issue information, and the format data is correctly recorded based on the content read from the read / write track 5. Then, the validity of the magnetic card 1 is confirmed (ST78).
[0089]
As a result, when the validity of the magnetic card 1 is confirmed, the control unit 21 guides the issuance of a correct card through the operation panel 22 and issues the magnetic card 1 from the issuing port 19 (ST79).
[0090]
If the validity of the magnetic card 1 is not confirmed in step 8, the control section 21 guides the card issuing abnormality through the operation panel 22 and ejects the magnetic card 1 from the issuing port 19 (ST80). .
[0091]
Further, the use processing of the magnetic card 1 is performed in the same manner as in the case of the flowchart shown in FIG.
As shown in FIG. 14, in the magnetic card 1, a high-retention recording magnetic material 55 is applied over the entire surface of the magnetic card 1 on the base layer 2, and only the one-time recording track 4 has an S magnetic material on it. 56 (two-layer configuration) may be applied.
[0092]
Further, as shown in FIG. 15, in the magnetic card 1, a magnetic layer 57 (a mixture of two types) in which an S magnetic material and a high-holding recording magnetic material are mixed is provided on the one-time recording track 4 on the base layer 2. The high-retention recording magnetic material 58 may be applied to the portion of the read / write track 5 on the base layer 2.
[0093]
Also in the case of FIGS. 14 and 15, the issuing process shown in FIGS. 5 and 6 and the use process shown in FIGS. 9 and 10 can be carried out similarly.
Also, as shown in FIGS. 1, 11, 14 and 15, in a magnetic card, a one-time recording track is composed of a mixture of two types of S magnetic material and high holding recording magnetic material or a two-layer structure. In the above, information to be concealed, such as issue information, may be recorded on the S magnetic body, and concealment information may be recorded on the high holding recording magnetic body.
[0094]
In this case, as shown in FIG. 16, the magnetic card issuing machine includes a read head for reading data written by the write head 16 for confirmation between the write heads 16 and 17 having the configuration of FIG. 20 is added. As shown in FIG. 17, the control circuit has a configuration in which a reading circuit 28 connected to the control unit 21 and outputting the content read by the reading head 20 to the control unit 21 is added to the configuration of FIG. .
[0095]
The issuing process of the magnetic card 1 in this case will be described with reference to a flowchart shown in FIG.
That is, the operation panel 22 specifies the amount of money to be issued, the issuing institution, the range of the applicable system, and the issue number as card issuing conditions, and then inputs a start key (not shown) (ST81).
[0096]
Then, the control unit 21 rotates the take-out roller 13 and the transport rollers 15,... By driving the transport mechanism 23 by the driver 24. Thereby, the magnetic card 1 stored in the stacker 12 is taken out by the take-out roller 13 and is carried by the carrying path 14 (ST82).
[0097]
Next, the control unit 21 transmits information indicating the amount of money, the issuing organization, and the range of the applicable system in issuance as basic issuance information corresponding to the issuance condition of the card specified by the operation panel 22, and encodes the issue number as $ D of the card. Is supplied to the write head 16 via the driver 25 (ST83).
[0098]
As a result, the write head 16 uses the S magnetic body 4a and the high-holding recording magnetic body 4b of the one-time recording track 4 to indicate the amount of money, the issuing institution, and the applicable system range in the issuance as basic issuance information. Is issued, and a DC erasing magnetic field is applied to the read / write track 5 to erase the track (ST84).
[0099]
As a result, the basic issue information is recorded on the S-magnetic body 4a of the one-time recording track 4 with a remarkably high coercive force, and the S-magnetic body 5a of the read / write track 5 enters an erase state with a remarkably high coercive force.
[0100]
Next, the one-time recording track 4 is read by the read head 20, and the read content is supplied to the control unit 21 via the read circuit 28 (ST85). Thereby, the control unit 21 confirms the validity of the magnetic card 1 by comparing whether the read content from the one-time recording track 4 matches the recorded basic issue information (ST86). .
[0101]
As a result, when the validity of the magnetic card 1 is confirmed, the control unit 21 sends the random data as the concealment information and the encoding information of the format data as the information of the initial value to the write head 17 via the driver 26. Supply (ST87).
[0102]
As a result, a magnetic field corresponding to random data is applied to the one-time recording track 4 by the write head 17, the basic issue information recorded on the high-holding recording magnetic body 4b is erased, random data is recorded, and read / write is performed. Initial value information, for example, format data is recorded on the track 5 (ST88).
[0103]
As a result, basic issue information is recorded on the S-magnetic material 4a of the one-time recording track 4 with extremely high coercive force, random data is recorded on the high-retention recording magnetic material 4b, The body 5a is in an erased state with a remarkably high coercive force, and format data is recorded on the high-retention recording magnetic body 5b.
[0104]
Further, the one-time recording track 4 and the read / write track 5 are read by the read head 18, and the read contents are supplied to the control unit 21 via the read circuit 27 (ST89).
[0105]
Thereby, the control unit 21 confirms whether or not the concealment has been correctly performed based on whether or not the read content from the one-time recording track 4 does not match the recorded random data (reading of the one-time recording track 4). The readability of the write head 17 and the effect of concealment of the one-time recording track 4 are checked.) The validity of the magnetic card 1 depends on whether the format data is correctly recorded based on the contents read from the read / write track 5. Is confirmed (ST90).
[0106]
As a result, when the concealment is confirmed and the validity of the magnetic card 1 is confirmed, the control unit 21 guides the issuance of a correct card through the operation panel 22 and issues the magnetic card 1 from the issuing port 19 (ST110). ).
[0107]
If the validity of the magnetic card 1 is not confirmed in steps 86 and 90, and the concealment is confirmed in step 90CanIf not, the control unit 21 guides the card issuance abnormality through the operation panel 22 and ejects the magnetic card 1 from the issuance slot 19 (ST110).
[0108]
Next, a process of using the magnetic card 1 will be described with reference to a flowchart shown in FIG.
That is, when the insertion of the magnetic card 1 from the insertion slot 32 is detected by a detector (not shown) (ST91), the control unit 41 drives the transport mechanism 43 by the driver 44 to correct the transport rollers 33,. Rotate in the direction. As a result, the magnetic card 1 inserted from the insertion slot 32 is transported by the transport path 34, passes through the read head 35, and is transported to the write head 36 (ST92).
[0109]
The control unit 41 supplies the DC erasing signal to the write head 36 via the driver 46 (ST93).
Thus, a DC erasing magnetic field is applied to the one-time recording track 4 by the write head 36 (ST94). As a result, the random data recorded on the high holding recording magnetic material 4b of the one-time recording track 4 is erased.
[0110]
Thereafter, the control unit 41 drives the transport mechanism 43 by the driver 44 to rotate the transport rollers 33 in the opposite direction. Thus, the magnetic card 1 from which the random data of the high-holding recording magnetic material 4b has been erased by the write head 36 is conveyed to the insertion slot 32 side by the conveyance path 34 (ST95).
[0111]
Next, reading of the magnetic card 1 is performed by the reading head 35. That is, information indicating the amount of money, the issuing organization, and the range of the applicable system in the issuance as the basic issuance information recorded on the (one-time recording track 4) (the S magnetic body 4a thereof). The usage record such as the remaining balance recorded on (the high holding recording magnetic material 5b of) the write track 5 is read, and the read content is supplied to the control unit 41 via the reading circuit 45 (ST96).
[0112]
The control unit 41 determines the validity of the read basic issuance information (ST97), and if determined to be valid, calculates the remaining amount as a new usage record by subtracting the fee for the current process from the remaining amount (ST98). At this time, the fee for the current process is specified by the operation panel 42, for example.
[0113]
Thereafter, the control unit 41 drives the transport mechanism 43 by the driver 44 to rotate the transport rollers 33,... Again in the forward direction. As a result, the magnetic card 1 read by the reading head 35 is transported by the transport path 34 to the side opposite to the insertion port 32 side (ST99).
[0114]
Next, the control section 41 supplies the random data and the remaining encoding information as the new usage record to the writing head 36 via the driver 46 (ST100). Thereby, the write head 36 records random data on the high holding recording magnetic material 4b of the one-time recording track 4, and records the remaining amount as a new use record on the read / write track 5 (ST101).
[0115]
Thereafter, the control section 41 drives the transport mechanism 43 by the driver 44 to rotate the transport rollers 33,. Thus, the magnetic card 1 on which the writing is performed by the writing head 36 is conveyed to the insertion port 32 side by the conveying path 34 (ST102).
[0116]
Next, the one-time recording track 4 and the read / write track 5 are read by the reading head 35, and the read contents are supplied to the control unit 41 via the reading circuit 45 (ST103).
[0117]
As a result, the control unit 41 confirms that the read content from the one-time recording track 4 cannot be read, and matches the read content of the read / write track 5 with the recorded new record of use to check the magnetic card 1. The validity is judged (ST104), the normal processing is guided by the operation panel 42, and the magnetic card 1 is ejected from the insertion slot 32 (ST105).
[0118]
If the basic issue information cannot be read in step 97, or if the validity of the magnetic card 1 is not determined in step 104, the control unit 41 informs the operation panel that the accepted magnetic card 1 is an abnormal ticket. In addition to being guided by 22, the magnetic card 1 is ejected from the insertion slot 32 (ST 106).
[0119]
As described above, in the case where the one-time recording track is composed of a mixture of two types of the S magnetic material and the high-retention recording magnetic material or a two-layer configuration, the S magnetic material records the issuance information to be kept secret, Random data is recorded on the recording magnetic material, and at the time of processing, the random data of the high-retention recording magnetic material is erased so that the issuing information of the S-magnetic material can be read. After the processing, the random data is again written on the high-retention recording magnetic material. It is recorded and ejected. Thereby, falsification and forgery are prevented.
