  • Publication number: 20180091694
    Abstract: According to one embodiment, a verification system includes a first replacement member and an image processing apparatus. The first replacement member is a replacement member of an image processing apparatus, detachably attached to the image processing apparatus, and provided with a machine-readable code. The image processing apparatus reads the code placed on the reading surface, transmits the read code image data or the like to a predetermined transmission destination in advance, and receives, from the transmission destination, the verification result of whether the data coincides with first information uniquely identifying the replacement member and registered in advance. The image processing apparatus permits an operation using the first replacement member when the verification result is positive and prohibits the operation using the first replacement member when the verification result is negative.
