I. Overview
There are hundreds of thousands to millions of Longquan swords on the market, and Longquan swords are sold all over the world through channels. However, when Baojian had an accident, the police went to the scene to deal with it. It was impossible to find the source of the sword through the sword, which made it very difficult to detect the case. In addition, Baojian’s anti-counterfeiting work is impossible.
Through the RFID traceability management system, combined with the technology of the Internet of Things, the chip is implanted into each sword. The smart chip uses a globally unique code, and the identity information of each sword is recorded in the chip. When selling the sword, the buyer’s ID card information is bound to the chip, so that by reading the chip, the production information of the sword and the buyer’s information can be obtained, so as to achieve the effect of anti-counterfeiting and solving the case.
Second, the use process
1. Baojian manufacturers implant chips
The manufacturer connects to the computer through the card issuer, and the computer network is connected to the database of the “RFID traceability management system”. Through the management software, the detailed information of the production time, origin, material, factory, and who made the sword can be recorded in the chip through the management software. The chip is unique in the world The code, embedded in the hilt of the sword, looks the same as the current sword.
Figure 1 Embedded chip
The chip needs to be built into the hilt to make the sword look the same as the current sword from the outside, to prevent malicious damage, and at the same time achieve the effect of anti-counterfeiting.

The card issuer is connected to the computer through a USB interface or wirelessly, and cooperates with the card issuing software to realize batch issuing of cards, without affecting the production efficiency of the manufacturer.
2. Dealers sell swords
When the dealer sells the sword, he needs to bind the production information of the sword with the buyer’s personal information, and finally bind it with the chip of the sword. There is a card issuer in the dealer’s store, which is connected to the computer via USB, which is convenient for reading the chip information in the sword. In addition, a second-generation ID card reader is connected. The buyer provides the ID card just like staying in a hotel, and then swipes on the reader to read the buyer’s identity information, click on the computer to confirm, and the system will display the buyer’s information Bind to the chip.
When the process is normal, the process card reader will pass the read tag number and the process number of the card reader to the system for unified processing, and the system can analyze and process the omissions in the first time.

3. Quickly locate the accident
When the police receives a case about Baojian, the police can take the handheld device to the scene of the crime, read the information of the built-in chip of the Baojian, and connect with the public security “traceability management system” through wireless GPRS to obtain the factory information and the buyer of the Baojian. Information, locate the suspect, provide great help to the detection of the case.

Figure 7 The sword is bound to the master of the sword
As shown in Figure 7 when the sword is bound to the sword owner, the sword number read is: LQ007339. The sword number needs to be communicated to determine the coding rules. If a one-dimensional barcode is to be pasted on the outside of the sword, it is recommended that the barcode information is consistent with this information. The ID number is 2560173D, which is unique in the world. It is written into the tag chip at the factory and cannot be changed.
Click on the event to enter the detailed information table. The handheld can display information such as the ID card, sword code, manufacturer, production date, sales store, store phone number, sword owner ID card, owner phone number, and owner address of the sword owner, which is convenient Solve the case as quickly as possible.
2. Computer monitoring software
Figure 8 Longquan Baojian Monitoring and Management System
“Longquan Sword Monitoring and Management System” uses Internet technology. As long as there is a network, you can check the latest situation of the registered Sword. The page rendering is shown above. Enter the account number, password and verification code and log in.
Figure 9 System architecture diagram
The system architecture diagram is shown above, you can see the information of the login person, login time and the police station to which it belongs.
Figure 10 Record registration information
On the registration page, you can see the owner’s ID card picture, sword owner’s name, ID number, owner’s contact information, sword brand, sword label, manufacturer, sales store, store phone number, sword brand, sword price and other information, as shown above . At the same time, you can also see the number of swords with chips installed and detailed information on each day.
Figure 11 Entering basic information
Before Baojian is sold to customers, the system needs to enter its detailed information, as shown above. The entry work needs to be completed by the manufacturer and the sales store. In the process of producing the sword, the manufacturer connects a card issuer to the computer, and enters the information of the sword brand, blade material, color, scabbard material, and sword label.
There is a computer in each store, which is connected to the Ethernet through a network cable or WIFI. The computer is connected to a scanner, a second-generation ID card reader and a card issuer. When the store purchases goods, the sales price, sales store, Information such as the store’s phone number and site is entered into the system.
When the customer wants to purchase, the customer needs to provide the ID card and contact information, put the ID card on the second-generation ID card reader, press the “read ID card” button on the interface, and the system can automatically recognize its information. The contact phone requires keyboard input. If the customer does not bring an ID card, he needs to provide his ID number and contact information.
