Abstract
A display method of an electronic identification device, a controller, an electronic identification device and a system are provided. The display method includes: controlling the electronic identification device to enter a working state from a sleep state, and obtaining to-be-displayed data; power consumption corresponding to the electronic identification device in the sleep state being lower than power consumption corresponding to the electronic identification device in the working state; and refreshing the to-be-displayed data to an electronic ink screen for display through a serial peripheral interface bus, and controlling the electronic identification device to enter the sleep state again after the refreshing is completed.
