Abstract: An information processing system includes an identification information acquisition unit configured to acquire identification information for identifying a user; a retaining unit configured to retain pieces of identification information for identifying users previously registered; an authentication unit configured to authenticate the identified user when the pieces of identification information retained in the retaining unit include the identification information acquired; a controller configured to register attendance information in which the identification information of the authenticated user and time information indicating an authentication time are associated with each other when the user is authenticated; a delay information acquisition unit configured to acquire delay information including delay time information indicating a delay time from a delay certificate; and a modification unit configured to modify, based on modification information in which the identification information of the authenticated us

Abstract: A disclosed image processing device includes: a media connecting portion including a first surface and a second surface forming a space for housing a protrusion type storage medium whose body protrudes from the media connecting portion and an insertion type storage medium whose body is inserted into the media connecting portion; a protrusion type slot portion for protrusion type storage media formed on the first surface; and an insertion type slot portion for insertion type storage media formed on the second surface. An insertion direction in the protrusion type slot portion is substantially orthogonal to an insertion direction in the insertion type slot portion.

Abstract: A reference-data storing unit stores reference data for determining whether to display image data by overwriting display data. A data converting unit converts the image data into display image data. A transparency determining unit determines whether a first pixel value of the display image data obtained through a color conversion by the data converting unit coincides with a second pixel value of the reference data stored in the reference-data storing unit. A data transfer unit that transfers, when it is determined that the first pixel value coincides with the second pixel value, the display image data to a display address space.

Abstract: An image processing system including an information processing unit, an image processing unit, a transmitter, and a charging unit. The image processing unit is connected to the information processing unit and conducts image processing selected by a user to obtain image data. The transmitter transmits the image data to an external receiver via a network. The charging unit charges a fee corresponding to the image processing selected by the user before the image data is transmitted to the external receiver.
