Description

Precious metal product purchase system

The invention relates to a precious metal product purchasing system, which is suitable for recycling precious metal products such as jewellery which is not purchased.

Precious metals such as gold, silver, platinum, etc., are used in precious metal jewelry such as ring necklaces because of their high jewelry decoration. In addition, various characteristics (durability, electrical characteristics, etc.) of precious metals are also used in industrial applications, and the use value of precious metals is high due to a wide range of uses. Relative to the increased demand for such precious metals, the supply of precious metals is derived from minerals buried in resources, and the amount of mining is limited. Therefore, it is important to be able to stabilize and ensure useful precious metal resources, and to construct a recycling system for refining and recycling used precious metals.

There has been proposed a precious metal product purchasing system for securing used precious metal resources (see Patent Document 1) as one of means for achieving recycling. In the purchase system of Patent Document 1, when the precious metal product such as used jewelry is recovered, the purchase price of the precious metal product is calculated based on the raw material metal price. Since the price of the raw material metal changes at any time in response to changes in the market economy, the purchase price is calculated by reacting the market information as in the system of Patent Document 1, and the purchase price can be appropriately adjusted to some extent.

The price of this raw material metal has risen sharply due to the revaluation of spot assets associated with the deterioration of the world's economic conditions in recent years or the increase in demand associated with the development of emerging countries. Therefore, there is a tendency for the sales of precious metal products to be rushed to increase. Therefore, the realization of the precious metal product purchasing system in such a situation can be said to be a particularly effective means for securing rare precious metal resources.

However, in the conventional precious metal product purchasing system like the one in the patent document 1, in addition to the jewellery, there are also insufficient purchases of shops of various commercial natures such as pawn shops, second-hand shops, recycling stores, and seal shops. Precious metal identification capabilities. Moreover, even in the case of identification, almost all of them are identified based on subjective factors such as design and brand, rather than the value of the precious metal such as the purity of the precious metal. As in this case, the traditional precious metal product purchasing system has different calculation methods for the purchase price, and there is no uniform standard, which sometimes causes an unidentified identification risk or includes a purchase fee. Therefore, there are many opaque places in the price setting, and the actual purchase price is a low price outside the customer's expectation.

In addition, in the traditional precious metal product purchasing system, most of the purchasers do not have the refined recycling technology of precious metals. Therefore, if the purchased precious metal products are in good condition, they will be directly sold or processed and then sold. Under such circumstances, sometimes impure materials are included in the resold products, which become a heavy quality or price damage in the precious metal products market. The factor. On the other hand, in the case where the purchased precious metal products need to be recycled and refined, the recycling purchaser who buys the precious metal products is resold to the professional refiner. Therefore, the purchase price is lower and opaque due to the increase in purchase handling fee and the rate of refining recovery loss and the like.

As described above, in the conventional precious metal product purchasing system, since the purchase price and the calculation basis are unknown, the customer's distrust feeling is caused and the selling intention is lowered. Accordingly, it is an object of the present invention to provide a precious metal product purchasing system which enables a customer to trust peace of mind by realizing a recycling purchase using an appropriate rating based on an objective precious metal value.

The present invention for solving the above problems includes: a main server that stores a purchase price of a precious metal product linked to a raw material metal price; a plurality of client terminals installed in each of a plurality of purchase stores, and the main server Connection, receiving the purchase price of precious metal products from the main server; and buying and selling processing unit, which is connected with the main server, and issues a sales commission to the market; the customer terminal calculates the purchase price of the precious metal product according to the purchase price of the precious metal products received by the main server. Producing purchase information of precious metal products containing the purchase price of precious metal products, and transmitting the purchased precious metal product purchase data to the main server; the main server storing the purchase information of the precious metal products received by the customer terminal; the sale and purchase processing unit, which includes A terminal that accesses the purchase information of the precious metal product stored in the main server, and issues a sales commission to the market based on the purchase information of the precious metal product.

In the purchase system of the present invention, the sale and purchase processing unit issues a commission for the sale of precious metals to the market based on the purchase data, so that it is possible to avoid the original The risk caused by changes in the price of metal. Therefore, when setting the purchase price, it is not necessary to increase the price by avoiding the risk, and it is possible to purchase the precious metal product with an appropriate price. Therefore, it is possible to maintain the trustworthiness of customers and to secure precious metal resources.

In the purchase system of the present invention, the type of the noble metal to be used is not particularly limited, but it is particularly suitable as a purchase system for gold (Au), silver (Ag), and platinum (Pt) which are highly versatile in precious metal products. The precious metal product purchasing system of the present invention will be described in detail below.

First, the "purchasing unit price of precious metal products" stored in the main server will be described. Although it is also possible to immediately link the purchase price of precious metal products with the price of raw material metals, it is also possible to link the purchase price of precious metal products with the price of raw material metals on a daily basis based on the price of raw materials at a specific time before the start of business. In the case of linkage on a daily basis, if the price of the raw material metal changes significantly within one day, it is better to match the purchase price with the change in the unit price.

The raw material metal price as the basis for setting the purchase price is determined based on the international transaction price of precious metals and the inter-bank foreign exchange market as the domestic precious metal price. Moreover, the update of the purchase unit price can be automatically updated as the price of the raw material metal is determined. For example, it is possible to set, after inputting the raw material metal price, by checking and acknowledging, and automatically updating the purchase unit price of the main server.

This is better: the purchase price of precious metal products is stored in the main server as: in grams, according to the product category (gold, platinum, silver, etc.) and precious metal grade (K24, K18, etc.).

The so-called precious metal grade indicates the purity of the precious metal, such as gold. In case, K24 (24 gold) means 100% purity, and K18 (18 gold) means 75% purity (18/24*100).

The above-mentioned purchase price of precious metal products is announced to allow customers who are entrusted to recycle precious metals to refer to better, so that the announcement data is in a state of available Internet access. The fee for purchasing the handling fee, the appraisal fee, the refining and recycling fee, etc. can be reflected in advance in the purchase price of the announcement. By calculating the unit price of the purchase of various expenses in advance by announcement, the calculation basis for the purchase of precious metal products is made clearer to the customer.

Following, the "purchase price of precious metal products" is explained. The client terminal calculates the purchase price based on the above-mentioned purchase unit price received from the host server based on the grade and weight of the precious metal recovered by the customer. According to the present invention, the purchase price of the precious metal product can be calculated based on the objective identification and the clear calculation standard. The calculation procedure of the specific purchase price is first, in the recycling purchase shop, the grade identification and weight measurement of the precious metal brought by the customer. In the purchase system of the present invention, it is assumed that the result of the grade identification at this time is correct, so that an analysis apparatus provided for analyzing the precious metal content in the precious metal product is preferable. In addition, the weight of the precious metal product is also preferably measured by a specific meter that has been qualified according to the metrological method. The purchase price can be appropriated based on these objective identification results, and the risk due to identification misidentification can be avoided.

Here, a machine such as a fluorescent X-ray inspection apparatus is used as an analysis device for analyzing the precious metal content in the precious metal product. However, in general, the fluorescent X-ray inspection apparatus for identifying precious metal grades is a very sophisticated device and is expensive, so in the past, it was difficult to purchase in each recycling. Shop settings. Therefore, the applicant of the present invention and the device manufacturer jointly developed a fluorescent X-ray inspection apparatus which is simple in operation, small in size, and inexpensive. In addition, an inspection device that is specially used for the identification of precious metal grades has been developed, and a low-cost and small-sized fluorescent X-ray inspection apparatus that can be installed in each recycling shop has been completed. In the precious metal product purchasing system of the present invention, it is preferable to provide the above-described small intensive fluorescent X-ray inspection apparatus for each precious metal recovery and purchase shop. The operation of this device does not require particularly difficult knowledge and skill, and the salesperson who recycles the purchase shop can also easily operate.

According to the above-mentioned grade identification and weight measurement, as well as the purchase price of precious metal products stored in the main server, the purchase price of precious metal products is calculated. Specifically, the purchase price of the precious metal grade corresponding to the identification result is taken out, and the purchased purchase price is multiplied by the purchased weight to calculate the purchase price. As described above, in the present invention, the purchase price can be calculated based on the purchase price of the precious metal product published on the line and the objective identification result, and the calculation standard can be clarified.

Based on the above-mentioned purchase price of precious metal products, the customer terminal can generate "precious metal product purchase information". The purchase information includes the purchase price of the calculated result, and also includes the precious metal grade and the weight as a basis for calculation. After the generated purchase data is transmitted to the main server by the client terminal, it is stored in the server by the main server.

The trading processing unit can access the purchase information of the precious metal products in the above main server. Specifically, the transaction processing unit may include a computer terminal connected to the main server via the Internet.

Moreover, the purchase and sale processing unit, based on the purchase information of the access, and the city A "selling commission" for precious metals was issued. Selling orders are better in a way that avoids the risk of changes in the price of raw metal. Specifically, it is possible to adopt a method of issuing a sales order or the like on the day of purchase of the precious metal. This is because even if the price of the raw material metal changes during the period in which the purchased precious metal is refined and recovered, it is not necessary to bear the risk of change at that time. For example, the sale and purchase processing unit can issue an online sell commission to the market based on the purchase information.

In addition, you can also issue a sell order by telephone or the like. According to the above-mentioned sale and purchase processing unit, since the risk of fluctuation in the price of the raw material metal can be reduced, it is possible to purchase a precious metal product at an appropriate price without adding a risk premium to the purchase and purchase of the precious metal product.

Regarding the above-mentioned sale of precious metals, there are stock markets and futures markets as specific trading markets for precious metals. The well-known London gold market is the spot market. In the London gold market, the negotiation between the parties is conducted. In the negotiation and negotiation, as long as the parties exist, the purchase of precious metals can be carried out 24 hours a day by entrusting the telephone between the parties.

Next, the risk avoidance in the precious metal product purchasing system of the present invention will be described in detail. As described above, the present invention can avoid the risk of fluctuation in the price of the raw material metal. However, in addition to the market price change, the risk of purchase of precious metal products is also due to the loss of purification recovery due to the amount of reduction that cannot be recovered during the purification of precious metals. This refining loss can be reflected in the purchase price of the precious metal product in advance, and if it is preset as a fixed fee, the risk of variation in the refining recovery rate becomes a problem. In the purification and recovery of precious metals, the purification recovery rate is different from the specific purification and recovery methods. The purity, shape, weight, and the like of the purified precious metal may vary. Therefore, in order to make the purchase price of precious metal products more appropriate, it is necessary to take measures against the fluctuations in the purification recovery loss.

Therefore, in addition to the above configuration, the precious metal product purchasing system of the present invention further includes a recovery rate calculating unit provided in the purification and recycling plant. The recovery rate calculation unit includes a computer terminal that connects to the main server via the Internet, thereby accessing precious metal product purchase materials. The recovery rate calculation unit calculates and stores the precious metal recovery rate when the purchased precious metal is actually purified and recovered based on the purchased purchase data. The main server can access the precious metal recovery rate stored by the recovery rate calculation unit, and can correct the purchase price of the precious metal product based on the recovery rate. By providing such a recovery rate calculation means, when the purification recovery rate greatly fluctuates, the fluctuation amount of the purification recovery rate can be reflected in the purchase price of the precious metal product, and the risk of fluctuation in the purification recovery loss can be avoided.

The calculation of the "precious metal recovery rate" of the recovery rate calculation unit and the purchase price correction of the precious metal product of the main server will be described in detail. First, the purification of the actual precious metal is carried out as follows. The precious metal to be purified and recovered is transported to a refinery and recycling factory. It is also possible to move the precious metals directly to the refinery and recycling factory from the recycling shop, and temporarily store them in the warehouse, and then move them to the factory after accumulating a certain amount. Then, the refined recycling plant of the precious metal to be transported is subjected to a treatment process such as melting, acid treatment or the like to purify and recover the precious metal. Then, the precious metal purified and recovered can be put into the market as a reusable resource by buying and selling processing units. In this way, precious metals can be realized The recycling cycle of resources.

In the case of the above-described precious metal purification and recovery, the recovery rate calculation means stores the amount of the precious metal before the purification and transportation to the factory, and the amount of the precious metal after the purification and recovery. The recovery rate calculation unit calculates the "precious metal recovery rate" from the ratio of the amount of the precious metal actually recovered to the amount of the precious metal before the recovery, and stores the precious metal recovery rate. The amount of precious metal before recycling used in the calculation of the precious metal recovery rate is used as the basis for the amount of precious metals shipped to the factory and the amount of precious metal purchased materials. This is to calculate the precious metal recovery rate corresponding to the purchase data of each precious metal product.

The main server can access the precious metal recovery rate calculated by the recovery rate calculation unit, and correct the purchase price of the precious metal product based on the recovery rate. Therefore, when the actual precious metal recovery rate of the refinery and recycling plant is greatly changed, the purchase unit price stored in the main server can be corrected, thereby avoiding the risk of variation due to the purification recovery loss.

Further, the correction of the purchase unit price in the main server may be, for example, a recovery rate calculation unit that transmits the calculated precious metal recovery rate to the main server, and the main server automatically corrects the precious metal recovery rate based on the received precious metal recovery rate. In this case, the purchase unit price may be corrected immediately at the time of receiving the precious metal recovery rate, or may be divided into daily or weekly periods, and corrected based on the average value of the precious metal recovery rate received during the period. As described above, as long as the purchase unit price is corrected in a timely manner, the risk of variation due to the loss of the purification recovery can be further reduced.

As described above, the "master server" of the present invention is, and the client terminal The precious metal recovery rate of the recovery rate calculation unit can also be accessed. The network configuration is not limited to the fact that the main server, the client terminal, and the recovery rate calculation unit are all disposed on the same network. Therefore, the network connecting the main server and the client terminal, and the network connecting the main server and the recovery rate calculating unit may be individual networks.

According to the precious metal product purchasing system of the present invention described above, it is possible to realize the purchase using the appropriate price based on the objective identification result. Therefore, it is possible to maintain the trustworthiness of the customer and to secure the rare precious metal resources.

BEST MODE FOR CARRYING OUT THE INVENTION

[Example 1]

Fig. 1 is a schematic view showing the configuration of a precious metal product purchasing system in an embodiment of the present invention. In the first figure, a plurality of client terminals 20 and a transaction processing unit 30 installed in the collection shop are configured to constitute a precious metal product purchasing system that is connected to the network via the main server 10. As long as the main server 10 can be connected to the network as described above, the actual server setting can be selected anywhere.

In the main server 10, the purchase price (in grams) of individual precious metal products of each grade (K24, K18, etc.) of each precious metal type (gold, silver or platinum) is stored, which is capable of accessing the Internet through the Internet. Metal prices are linked. The unit price of the purchase is linked to the price of the raw material metal before the start of the store operation, and is automatically corrected daily. When the price of the raw material metal exceeds the large price change of the usual variation, the purchase price will be temporarily corrected during the business hours. In addition, the purchase price has already reflected the purchase fee and The fee and the refined recycling fee. In each of the purchase shops in which the client terminal 20 is provided, a fluorescent X-ray inspection apparatus for authenticating when the purchase price of the precious metal product is calculated, and a specific gauge that is qualified according to the measurement method are provided. In addition, the sale and purchase processing unit 30 can issue a sell order to the market via the Internet.

Next, the flow of the specific purchase processing of the above-described precious metal product purchasing system will be described based on the processing flow of FIG. First, the main server 10 transmits the purchase price of the precious metal product linked to the change in the price of the raw material metal to each of the client terminals 20 (S110). On the other hand, the client terminal inputs the result data of the grade and weight of the precious metal identified at the purchase shop in accordance with the customer's purchase purchase request (S120). The result of the identification of the input terminal is the precious metal grade measured by the fluorescent X-ray inspection apparatus and the weight of the precious metal measured by the metrology method. Then, the client terminal calculates the purchase price of the precious metal product based on the purchase unit price of the precious metal product received by the main server and the input identification result (S125). Specifically, the purchase price of the precious metal product can be calculated by multiplying the purchase price of the precious metal grade corresponding to the identification result by the weight of the precious metal.

As described above, in the purchase system of the precious metal product of the present invention, the precious metal grade and weight are objectively identified based on the general purchase price of the precious metal product purchased by the general public, and the fluorescent X-ray inspection apparatus and the meter which is qualified according to the law. The purchase price of precious metal products. Therefore, it is possible to realize a purchase using an appropriate evaluation based on a clear calculation standard. In addition, it is also possible to adopt a system that produces a specification in which a purchase price calculation standard is described, and allows the customer to confirm the purchase unit price, precious metal grade, weight, and the like.

Next, the client terminal generates the purchase information of the precious metal product and transmits it to the main server (S126). In the present embodiment, the purchase information of the precious metal product includes: the name of the purchase shop, the time of purchase, the grade of the precious metal as the result of the identification, and the weight, the purchase price, and the purchase price of the precious metal product at the time of purchase. The main server stores the purchased precious metal product purchase data in the server (S115).

Then, the transaction processing unit accesses the purchase information of the precious metal products in the main server, and issues a sales commission to the market according to the purchase data (S130, S135). For example, when the price of raw material metal is significant, the time to issue a sell commission can be delayed to minimize the risk of changes in the price of raw metal.

In the purchase system of the first embodiment, the risk caused by the variation in the price of the raw material metal can be reduced, and the purchase with an appropriate price can be realized. Furthermore, when calculating the purchase price of the precious metal product, a clear calculation standard can be recorded in the specification based on the actual identification result.
