Materials that need to be used for a period of time to settle the balance can be read and paid again.

The dual-frequency RFID tag is divided into a non-encrypted area, an encrypted area and a payment encrypted area.

In this embodiment, the data is signed and encrypted through the electronic certificate issued by the certification center, which effectively improves the accuracy of identity confirmation and the confidentiality of the data, and ensures the security of the payment process; the signed and encrypted data are written into the double When the materials are sent to the buyer's warehouse, the buyer's warehouse personnel use RFID handheld devices to scan the materials in batches through ultra-high frequency technology to check whether the data is consistent with the real object, and speed up It improves the work efficiency of workers, and the verification is convenient and quick.

The following is an example to illustrate the settlement method based on dual-frequency RFID, which includes the following steps:

Step S201, the authentication center system manages USB shields, electronic certificates, keys, etc. The constraints of the authentication center system server are: meet the configuration requirements of the mainstream security authentication system servers in the industry; upstream and downstream enterprises in the supply chain such as Huawei, ZTE, Nokia, etc. Manufacturers apply for electronic certificates to the certification center. After the approval, the certification center produces their own electronic certificate information for each manufacturer and binds them to the USB shield. The USB shield is then issued to the corresponding manufacturer. The constraints of the USB shield are: high security level certificate, The key is out of the USB shield;

In step S202, the upstream and downstream enterprises in the supply chain use desktop computers and USB shields during the delivery process to encrypt the original delivery information such as company information, material code, material description, material quantity, etc., and store them in the dual-frequency RFID tag. The material code, material description, material quantity and other information are stored in the non-encrypted area of the dual-frequency RFID tag in an unencrypted form, which is convenient for later RFID handheld devices and NFC mobile phones to read the tag information. The desktop constraints are: intel I7 processor, 8G memory, 200MB free space, Window 7/8/10 32-bit/64-bit operating system;

Step S203, the encrypted information is transported to the Henan Mobile warehouse along with the dual-frequency RFID tag, and the warehouse operator uses the RFID handheld device to read the encrypted information from the dual-frequency RFID tag, and then uploads the encrypted information to the Henan Mobile supply chain system;

Step S204, the Henan Mobile supply chain system decrypts the encrypted information using the applied electronic certificate, obtains the signature, verifies the authenticity of the signature, outputs the enterprise information, material code, material description, material quantity, etc., and returns the above information to the RFID handheld devices;

Step S205, the warehouse operator checks the returned information and the on-site materials to confirm whether they are consistent, and if they are consistent, notify the Henan Mobile financial system to pay to the upstream and downstream enterprise financial systems of the supply chain;

Step S206, after the material is installed at the final use site, the acceptance personnel read the high-frequency data of the electronic tag through the NFC mobile phone, pass the system authentication and decryption, and then notify the Henan Mobile financial system to pay the material to the financial system of the upstream and downstream enterprises in the supply chain. Remaining funds;

In addition, for materials that need to be used for a period of time to settle the balance, you can read and pay again.

The settlement method based on the dual-frequency RFID in this embodiment can realize the function of one-time settlement and payment of inter-enterprise material payments or multiple settlement and payment functions.

In the warehouse, warehouse managers can use RFID handheld devices to scan materials in batches through UHF technology. UHF technology has the advantages of long transmission distance and fast transmission speed. It is convenient and fast to operate, and can quickly obtain relevant information about materials; when After the materials are installed at the place of use, the acceptance personnel read the high-frequency data of the dual-frequency RFID tag through the NFC mobile phone. The high-frequency technology has the characteristics of short transmission distance. The dual-frequency RFID tag of the present invention has two types of chips: an ultra-high frequency chip and a high frequency chip. In different application scenarios, warehouse managers can read the data in the corresponding chips.

The above are only the preferred embodiments of the present invention. It should be pointed out that for those skilled in the art, without departing from the principles of the present invention, several improvements and modifications can be made.
