The money identification device 6 includes a control unit 61 including a storage unit 61a and a transmission / reception antenna 62. The storage unit 61a includes a transmission / reception frequency for each denomination. ID, denomination code, production lot, and serial number are stored.
FIG. 6 is a schematic configuration diagram showing an external appearance of the currency identification device 6, which has a mounting table 63 on the upper surface, and as shown in FIG. 6, a plurality of ID-attached currencies (for example, one thousand-yen ID banknote 1 is one piece). 2 pieces of 1-yen ID coins 3) are placed on the placing table 63, and the total amount of the placed ID money is received by the transmitting / receiving antenna 62.
FIG. 7 is a memory layout diagram showing the allocation of each denomination. As shown in FIG. 5, the receiving frequency, ID, and denomination of 10,000 denominations of 10,000 yen to 1 yen currently issued in Japan. A code, a production lot, and a serial number are assigned and stored in the storage unit 61a.

In the above configuration, the processing of the currency with ID will be described with reference to the flowcharts of FIGS.
First, in the standby state, when money is placed on the placing table 63 of the money recognition device 6 (step S1), first, from the transmission / reception antenna 62 on the money recognition device 6 side, for example, a large denomination. It switches to "100 MHz" which is the frequency of the ID bill 1 of 10,000 yen (step S2), and transmits an ID response instruction (step S3). Here, if the 10,000 yen ID banknote 1 is placed on the placing table 63, a response signal is transmitted, and it is determined whether there is an ID response (step S4). If there is an ID response (step S4, Yes), 10,000 yen is set as the identification result (step S5), and then the number of identifications is set (step S6).
At this time, the ID, lot number, and serial number are also set in the storage unit 61a.

On the other hand, if there is no ID response (step S4, No), the frequency is switched to the next-ranked currency frequency, and finally the processing is performed by switching to the ID coin 3 of 1 yen to calculate the total amount.
Next, the total amount calculation processing of the ID-added money when the ID-added money of “1002 yen”, which is an example shown in FIG. 6, is placed on the placement table 63 will be described.
First, in the standby state, when money is placed on the placing table 63 of the money recognition device 6 (step S1), first, from the transmission / reception antenna 62 on the money recognition device 6 side, for example, a large denomination. It switches to "100 MHz" which is the frequency of the ID bill 1 of 10,000 yen (step S2), transmits an ID response instruction (step S3), and determines whether there is an ID response (step S4). In this case, since there is no ID response to the frequency of the 10,000 yen ID bill 1 (step S4, No), the process proceeds to step S7.

In step S7, the frequency is switched to the frequency “101 MHz” of the ID bill 1 of 5,000 yen, an ID response instruction is transmitted (step S8), and it is determined whether there is an ID response (step S9). In this case, since there is no ID response with respect to the frequency of the ID bill 1 of 5,000 yen (step S9, No), the process proceeds to step S12.
In step S12, the frequency ID banknote 1 of 2000 yen is switched to “102 MHz”, an ID response instruction is transmitted (step S13), and it is determined whether there is an ID response (step S14). In this case, since there is no ID response to the frequency of the 2000 yen ID banknote 1 (step S14, No), the process proceeds to step S17.
In step S17, the frequency is switched to the frequency “103 MHz” of the thousand yen ID banknote 1, an ID response instruction is transmitted (step S18), and it is determined whether there is an ID response (step S19). Here, as shown in FIG. 7, one thousand yen ID banknote 1 is placed on the mounting table. Therefore, it is determined that there is an ID response (step S19, Yes), and a thousand yen is set as the identification result (step S20). Subsequently, the number of sheets is determined based on the reception level and one identification number is set (step S21), and the process proceeds to step S22.

In step S22, the frequency is switched to “104 MHz” which is the frequency of the ID coin 3 of 500 yen, an ID response instruction is transmitted (step S23), and it is determined whether there is an ID response (step S24). In this case, since there is no ID response to the frequency of the 500 yen ID coin 3 (step S24, No), the process proceeds to step S27 in the flowchart of FIG.
In step S27, the frequency is switched to the frequency “105 MHz” of the 100-yen ID coin 3, an ID response instruction is transmitted (step S28), and it is determined whether there is an ID response (step S29). In this case, since there is no ID response to the frequency of the 100 yen ID coin 3 (step S29, No), the process proceeds to step S32.
In step S32, the frequency is switched to the frequency “106 MHz” of the 50-yen ID coin 3, an ID response instruction is transmitted (step S33), and it is determined whether there is an ID response (step S34). In this case, since there is no ID response to the frequency of the 50-yen ID coin 3 (step S34, No), the process proceeds to step S37.

In step S37, the frequency is switched to the frequency “107 MHz” of the 10-yen ID coin 3, an ID response instruction is transmitted (step S38), and it is determined whether there is an ID response (step S39). In this case, since there is no ID response to the frequency of the ID coin 3 of 10 yen (step S39, No), the process proceeds to step S42.
In step S42, the frequency is switched to the frequency "108 MHz" of the 5-yen ID coin 3, an ID response instruction is transmitted (step S43), and it is determined whether there is an ID response (step S44). In this case, since there is no ID response to the frequency of the 5-yen ID coin 3 (step S44, No), the process proceeds to step S47.
In step S47, the frequency is switched to "109 MHz" of the 1-yen ID coin 3, and an ID response instruction is transmitted (step S48), and it is determined whether there is an ID response (step S49). Here, as shown in FIG. 7, two 1-yen ID coins 3 are placed on the mounting table, so that an ID response is present (step S49, Yes), and 1 yen is set as the identification result (step S50). Subsequently, the number of sheets is determined based on the reception level and two identification sheets are set (step S51).

In this way, it is identified that one thousand yen ID banknote 1 and two one-yen ID coins 3 are placed on the placing table 63, and 1002 yen is output to the host device. (Step S52), the identification of the currency with ID is completed.
In this way, in response to the frequency transmitted by the currency with ID, the ID is transmitted to the currency identification device 6 side, and this ID is received by the currency identification device 6 so that the “true” ID is obtained. It is determined that the money is attached money, and after this determination, the authenticity determination is further performed by determining the lot number and the serial number.
Further, the lot number and serial number are assigned at the time of issuing money with ID, and there is no same number, and it is easy to track the determination of fake money with ID or the circulation of money with ID.

  Furthermore, even if a plurality of ID-attached coins are placed on the mounting table, it is not necessary to determine by placing them on the mounting table one by one by switching the frequency and sequentially determining them.
