In this step, there are many ways to select frequencies, for example, the client converts the identification information into a number and divides the number by the number of unassigned frequencies to obtain a remainder; and the client selects corresponding frequencies according to the remainder, wherein the client sorts 0, 1, 2 to N-1 according to the size of the unallocated frequencies, wherein N is the number of the unallocated frequencies. Or as a simpler implementation, the client randomly selects one of the unassigned frequencies as the frequency corresponding to the good.
And step S108, the client sends the selected preset frequency, the identification information of the goods and the geographical position information to a server for storage.
Step S110, the client writes the data to be written in the RFID tag into the RFID tag using the predetermined frequency, where the number of the RFID tags is multiple, and each piece of goods in the batch of goods is attached with one RFID tag. There are many kinds of data to be written to the RFID tag, which can be written as needed. For example, the data to be written to the RFID tag includes at least: the geographic location information; the geographic position information is obtained through a Beidou positioning system on the mobile terminal.
