AUTHENTICATING A CONSUMABLE PRODUCT BASED ON A REMAINING LIFE VALUE
摘要
Authenticating a consumable product based on a remaining life value includes determining whether an identifier stored in memory of a consumable product is listed in a device history and concluding that the consumable product is not authentic if the device is determined to have used the consumable product previously based on the device history and a current remaining life value associated with the consumable product indicates less use than a recorded remaining life value for the consumable product associated with the identifier in the device history.
