Abstract
The present invention relates to the technical field of printer consumables, and particularly relates to a consumable chip, a consumable and a consumable communication method. A session key for communication authentication is determined based on a communication session chip count which is selected by the consumable chip and stored in a storage device. The calculation process of the communication session chip count is avoided, thereby increasing the response speed of the consumable chip for a read request of an imaging device, and reducing the error rate.
