Claim:
An information processing system comprising: an electronic paper; and an information processing device that processes information from the electronic paper, wherein the electronic paper includes: a display that displays document data without power supply and that allows a user to add an external note on a surface of the display; a memory that stores a document id of the document data to be displayed on the display; and a first radio section; the information processing device includes: a second radio section; a data extraction unit that acquires the document data from a document memory based on the document id which is sent through communication between the first radio section and the second radio section; a first transport path that transports a paper medium; a second transport path that is different from the first transport path, and transports the electronic paper without applying a bend on the electronic paper; a scanner having a sensor that detects whether or not an object to be scanned is the electronic paper, the scanner being configured to scan the display of the electronic paper and obtain an image thereof; a transport path selection unit that selects the first transport path or the second transport path based upon the detection by the scanner; a difference processing unit that obtains a note image as a difference between an image of the document data from the memory of the information processing device and the scanned image of the display, the note image corresponding to the external note added to the surface of the display of the electronic paper; and a data generation unit that generates data by associating the note image and the document data.
