As shown in FIG. 2, the calling method according to the present embodiment includes steps 201 to 208.

In step 201, the electronic price tag device receives an update instruction sent from the server, and updates the price tag information stored in the electronic price tag device according to the update instruction. The update instruction includes price tag information for updating, and the price tag information for updating includes the first position information of the electronic price tag device.

The electronic price tag device is generally used for displaying the price tag information of a commodity to a user, so that the user can purchase the commodity according to the price tag information.

The update instruction may include the price tag information for updating, and the price tag information for updating may include commodity name, commodity price, commodity origin, and the first position information of the electronic price tag device. The first position information indicates a position where the electronic price tag device is located, and for example, the first position information is a shelf number of a shelf where a commodity corresponding to the electronic price tag device is located.

After receiving the update instruction sent from the server, the electronic price tag device may replace original price tag information according to the price tag information for updating carried in the update instruction, and therefore the purpose of updating the price tag information is achieved.

When the electronic price tag device is initialized, the server sends an update instruction to the electronic price tag device to initialize the electronic price tag device. In this case, the update instruction includes price tag information, which is price tag information of a corresponding commodity in the initialization process, so as to realize the initialization update of the price tag information.

When the price tag information of the commodity changes, the server sends an update instruction to the electronic price tag device so that the electronic price tag device can update the price tag information. In this case, the update instruction includes price tag information for updating, which is price tag information of a corresponding commodity to be updated in the update process. The electronic price tag device can replace original price tag information with the price tag information for updating included in the update instruction, so that the price tag information is updated.

In step 202, the electronic price tag device determines whether an operation instruction of a user is received, and if the operation instruction of the user is received, step 203 is performed; otherwise, step 202 is repeated.

The electronic price tag device is in a standby state after completing the update of the price tag information, and at this time, the electronic price tag device determines in real time whether or not an operation instruction of the user is received (step 202). The operation instruction of the user may be an operation instruction generated by, for example, pressing a call button on the electronic price tag device.

In step 203, the electronic price tag device generates request information according to the operation instruction of the user, and sends the request information to the server. The request information includes the first position information of the electronic price tag device.
