It is set to be recorded.

In such a configuration, the case where the medium 10 is issued will be described first with reference to the flowchart of FIG. 12.

When the medium 1O is fed from the medium accumulation section (not shown) of the authentication reading device (step S1), the passage sensor 23 detects the feeding of the medium 10, and this detection signal TS is sent via the amplifier 30. The decoding unit 20 is manually operated. As a result, the rollers 638 to 63E are rotated in the direction M in FIG.

and C2 are output.

By the way, barcodes 15 and 16 are printed on the barcode band 13 using characters as shown in FIG. 5, but here the details of the start character and the first character are shown in FIG. 9(A). , the reading operation will be explained below.

As shown in Fig. 9 (A+), each character is composed of one trigger bar S1.52 and a data bar consisting of four bars composing data. A fIn material with a specific coercive force is included and printed, and here the trigger bars St, S

Z is recorded depending on the presence or absence of the bar mark II in 2 (for example, the 20-dotted line part in the data bar in the first character shown in FIG. 9 (8)). Therefore, when the start character and first character of the barcode 15 are detected by the magnetic detection means 21, the amplifier 26 outputs an output waveform MD2 as shown in FIG. 9(B). Here, since the trigger bars Sl and S2 are made of a magnetic material with a high coercive force, a waveform with a high peak value is detected, and the data bars 11 and 2 are made of a magnetic material with a low coercive force, so a waveform with a high peak value is detected. A waveform with low high values is detected. The barcode detection signal MD2 is sent to the reading circuit 27.
and 28, or input to the reading circuit 27 in FIG.

Therefore, the reading circuit 27 outputs a digital signal C1 which is binarized at the threshold level Ti11 and has the timing shown in FIG. 9(D), and the zone timing of the bar within the character is calculated from this timing. be done. Further, from the reading circuit 28, the binarized data shown in FIG.
E) The digital signal C2 shown in FIG. The presence or absence of bar printing up to the fifth character is detected. In this way, since the trigger bar is printed at the beginning of each character using a magnetic material having a different lin retention force than the data bar, only the data of each character can be extracted. Furthermore, the barcodes 15 and 16 can be identified by the fixed data of the end characters.

The decoding unit 20 converts the digital signals CI and C2 read by the reading circuits 27 and 28 into an algorithm layer, as described above.

Next, the collation unit 44 reads out the decoded data stored in the storage unit 51 and the storage unit 52 and collates it (step S5), and when the two match, generates basic data α and stores it in the storage unit 45. do. The encryption circuit 39 encrypts the stored basic data α into α° according to algorithm A3 (step S7). Note that when the basic data α do not match, the medium IO is taken into the device and recovered (steps S5 and S6). Here, other information MN as described above is collected.

and encrypts it into t+g data β according to algorithm B, and writes it in the storage circuit 43 (step S9).
. When the storage circuit 43 completes the encryption, it inputs the encrypted data β to the driver circuit 34, and the driver circuit 34 operates the writing means 33. At the same time, the decryption unit 20 rotates the rollers 638 to 83E again in the direction M in FIG. (Step 5)

The rollers 63^ to 63E are rotated again in the N direction, and the magnetizing/demagnetizing means 31 is operated to obtain usable frequency data for the barcodes 15 and 16 of the barcode band 13 (this is from the other information data output section 41). Other information (included in MN2) is magnetized and recorded (step 511), and a medium IO is issued (step 512). In this magnetization, for example, only the trigger bars of each character of the barcodes 15 and 16 are magnetized according to the frequency data, but it is also possible to magnetize each character including the data bar. Furthermore, if the next medium 10 is to be issued continuously, step 5 above is performed.
1, data is recorded on the medium 10 and issued by the same operation as described above (step 513.51).

Next, a payment method using the medium 10 will be explained with reference to the flowchart of FIG. 13.

As in the case of issuance described above, when the medium 10 is inserted into the authentication reading device, the medium 10 is taken inside, and the signal MD3 is first detected by the frequency detection means 90 from the magnetized barcode 15.16 of the barcode band 13. detected (step 52)
0), the signal M[14 amplified by the amplifier 91 is output from the reading circuit 92 as a binarized digital signal C3.

Here, regarding the operation of reading the digital signal C3 from the barcode band 13 which is converted into 6fl according to the frequency data, refer to Fig. 1θ (8) to (0) shown in correspondence with Fig. 9(A). I will explain. Note that here, an example is shown in which frequency data is magnetized for each character. As shown in FIG. 1θ (A), when the medium IO is issued, the magnetizing/demagnetizing means 31 causes the start character and the trigger bars SL, S2 . 1 in the data bar. to 2
is magnetized according to the power data DS (for example, 2), so the signal MD3 detected by the power detection means 90
is input to the amplifier 91, and outputted as an output waveform MD4 as shown in FIG. 9(B). This read signal MD4 is input to the read circuit g2, but the read signal MD4 is inputted to the read circuit g2 as shown in FIG.
Since the threshold level Tl11 shown in ) is set, the digital signal C3 is binarized at this threshold level Tl-11 and outputted as the digital signal C3 with the timing shown in FIG. Then, this digital signal C3 is manually inputted to the frequency detection section 93 for power determination (step 521), and is outputted as frequency data DS, and is also manually inputted to the frequency checking section 94.

On the other hand, when the medium IO is taken in, the On code data β is read from the magnetic recording band 12 by the magnetic detection means 22 (step 522), and this encrypted data β is decrypted by the decryption unit 35 using algorithms B and A3. The basic data α is stored in the individual basic data recording section 36, and the other information is stored in the other information data recording section 38 and output as magnetic recording information MNI. (step 523). Then, the information MNl is input to the frequency checking unit 94 for frequency checking,
It is compared with the frequency data DS detected by the frequency detection means 90 described above (step 524), and when they match, a frequency matching signal O is output to the decoding section 20 (step S25.
527). Also, if the frequency data does not match, use medium 10.
The medium 1O is treated abnormally as unusable or inauthentic, and after issuing a warning with a lamp or sound for a certain period of time, the medium 10 is returned or taken into it (steps 525 and 526).

Next, the rollers 638 to 63E are rotated in the N direction in FIG. 6 to return the medium 10 to a predetermined position, and then the rollers are reversely rotated to take the medium 10 into the apparatus again. At the same time, 6n is attached to the barcodes 15 and 16 by the young magnetic eraser 6n means 31 (step 528). Then, the residual 6J of barcodes 15 and 16 is detected by the magnetic pressure detection means 21.
,! Qi is detected (step 529) and reading circuit 27.
28, digital No. 43 C1°C2 is obtained, the data decoded by the decoding unit 20 is stored in the storage unit 51, 52, the basic data α is output from the collation unit 44, and the data is stored in the storage unit 4.
5 (step 530). Here, comparison section 3
Step 7 compares the basic data α stored in the storage unit 45 with the basic data α stored in the individual basic data storage unit 36 (step 531), and if they match, outputs an authentication signal light and sends the medium 10 is confirmed to be genuine, and payment processing is performed (steps 532 and 534). If they do not match, the medium 10 is treated as not genuine and an abnormality is processed, and after a certain period of time a lamp or sound alarm is issued, the medium 10 is returned or collected (steps S32, 533).
.

After the payment process, whether the data newly generated by the payment and the frequency data from which one dose has been subtracted are manually input to the other information data storage unit 38 based on the payment process, or the frequency is determined at this time (step 535). , if there is no remaining power, the medium lO
is taken into the collection section installed in the device and collected (
Steps 536, 537). If there is a remaining number of degrees, the above-mentioned basic data α is encrypted into α° by the encryption circuit 39 (step 538), and this α° and other information data recording unit 38 are updated as magnetic recording information MNI. The calculated frequency data and other information are mixed in the data mixing section 40 (step 539), and the encrypted data β is generated in the encryption circuit 42.
(Step 540), and this encrypted data β is magnetically recorded in the 6II record 1F12 of the medium 10 by the writing means 33 (Step 541). Also, the decoding unit 20
The barcode 15 is used to record the frequency data updated in the barcodes 15 and 16 by the magnetization/demagnetization means 31.
and 16 residual magnetism (in the example of FIG. 10, the start character) is demagnetized.

Here, the operation of updating and recording frequency data from barcodes 15 and 16 will be explained with reference to FIGS. 11 (8) to (D).

FIG. 11(8) corresponds to FIG. 1O(8), and the magnetizing/demagnetizing means 3 sets 1 to the trigger bar 31 and data bar of the start character attached in step 528.
By erasing 6n by 1, the frequency data is updated Pfi(2
-1-1) and record it. As a result, the signal MD3 is detected from the frequency detection means 90 at the next payment for the medium 10, and the amplifier 91 outputs the signal MD4 as shown in FIG. 11(B), and no signal is output from the start character. Then, in the reading circuit 92, as shown in FIG.
Since the signal is binarized at the threshold T111 shown in C), a digital signal C3 as shown in FIG. 11(D) is generated.
is output. As a result, the frequency (in this example, 1) of the medium is detected. When the update recording of the frequency data is completed in this way, the rollers 53A to 63E are moved to the sixth position.
Rotate in the N direction in the figure and return the medium 10 (Step 5
43).

(Modified example of the invention) In the above embodiment, two algorithms, layer and A2, were used as algorithms for OF1 encryption and decryption of encrypted data. 19, and the n pieces of encrypted data are encoded into the above nff
