Claim:
A sheet processing system having a sheet processing apparatus and a server, the server comprising: a sheet data storage unit configured to store, as sheet data, the identification data of each sheet and the result of processing the sheet in association; and a first transmission unit configured to transmit the sheet information stored in the sheet data storage unit, to the sheet processing apparatus, and the sheet processing apparatus comprising: a storage unit configured to store the sheet information received from the server; a sheet hold unit configured to hold sheets; a sheet feed unit configured to feed sheets, one by one, from the sheet hold unit; a conveyor unit configured to convey sheets fed by the sheet feed unit; an image acquisition unit configured to acquire images of each sheets conveyed by the conveyor unit; an identification-data recognition unit configured to obtain the identification data from the images acquired by the image acquisition unit; a discrimination unit configured to refer to the sheet information stored in the storage unit, thereby to discriminate the sheet based on the identification data obtained by the identification-data recognition unit; and a collection unit configured to classify the sheets into groups on the basis of the result of discrimination performed by the discrimination unit, and to hold the groups of sheets thus formed; wherein the discrimination unit discriminates a sheet as a rejected sheet when history information representing that the sheet has been discriminated as being a forged sheet is associated with the identification data obtained by the identification-data recognition unit, in the sheet data that is stored in the sheet data storage unit; and wherein the storage unit is configured to extract sheet information according to input from the sheet data storage unit of the server and to store the extracted sheet information.
