A sheet conveying apparatus of an embodiment includes a conveyance path along which a sheet can be conveyed, and a plurality of conveyance rollers configured to move a sheet along the conveyance path. A wireless tag reader/writer is configured to read information from, and write information to, a wireless tag of a sheet on the conveyance path. A phase change detector is configured to detect a phase change in response waves received by the wireless tag reader/writer from a wireless tag. A tag specifying unit is configured to identify whether a wireless tag is moving along the conveyance path based on the detected phase change in response waves from the wireless tag. A controller controls the wireless tag reader/writer to write information to the wireless tag identified as moving along the conveyance path.

A sheet conveyance device has a sheet conveyance path with a first path and a second path. A wireless tag communication device can write information to a wireless tag on a sheet on the first and second paths and receive responses from the wireless tag. A controller controls the wireless tag communication device to attempt to write information to the wireless tag while on the first path, then determines whether information has been written to the wireless tag on the first path according to a response received from the wireless tag. The controller switches a conveyance destination for the sheet to the second path if the information has not been written or to a discharge location if the information has been written. The controller then controls the wireless tag communication device to attempt to write information to the wireless tag while the sheet is on the second path.

An image processing device includes a printing unit printing an image on a sheet including first and second tags. The first and second tags have first and second antennas extending along first and second directions. The device further includes a tag reading unit including a third antenna and configured to transmit, towards the sheet from the third antenna, first radio waves polarized in the first direction and second radio waves polarized in the second direction in each of a first period during which the sheet is conveyed towards the third antenna and a second period during which the sheet is conveyed away from the third antenna, and determine an orientation of the sheet based on intensities of third radio waves polarized in the first direction and fourth radio waves polarized in the second direction, which have been received by the third antenna in each of the first and second periods.

An image forming apparatus includes an information storing unit, an information acquiring unit and a control unit. On the basis of association between pieces of identification information stored in the storing unit and pieces of user information, the control unit authenticates the use of the image forming apparatus by a user corresponding to an associated piece of identification information. Upon acquisition by the acquiring unit, of a piece of identification information which is not stored in the storing unit, the controller unit causes a display portion to display display regions corresponding to pieces of user information so as to be selectable to cause the storing unit to store piece of identification information and a corresponding piece of user information in association with each other.

A method of detecting fraudulent use of a printing device including a non-contact memory tag, including receiving a request to read the tag, receiving information from the tag, determining an installed configuration of the printing device from the information, comparing the installed configuration to a current configuration of the printing device, and in response to determining that the current configuration is not the same as the installed configuration, indicating that a violation exists.

An image forming system includes an image forming apparatus and a writing device. The image forming apparatus includes an input and output unit and an image forming unit. The input and output unit acquires image information and write information to be written to a wireless tag. The input and output unit outputs the write information to the writing device. The image forming unit forms an image on a sheet to which the wireless tag is attached, based on the image information. The writing device includes an acquisition unit and a writing unit. The acquisition unit acquires the write information. The writing unit writes the acquired write information to the wireless tag via an antenna.

An information processing apparatus capable of executing near field wireless communication, comprises: a display unit configured to display a screen; an obtaining unit configured to obtain identification information regarding a device from a near field wireless communication tag with use of the near field wireless communication; a selection unit configured, in a case where the obtaining unit obtained the identification information, to select one of first processing for connecting to the device indicated by the identification information and second processing for connecting to the device indicated by the identification information and sending data to the device, based on a type of screen being displayed by the display unit; and a processing unit configured to execute the processing selected by the selection unit.

An image forming apparatus includes an image forming portion capable of forming an image on a sheet on the basis of image data image data sent from a portable terminal; a display panel for displaying a reading image including information for permitting wireless communication with the apparatus and readable by a camera of the portable terminal; and a controller capable of executing an operation in a first mode in which the display panel is turned on in a state that a main switch of the image forming apparatus is turned on and an operation in a second mode in which electric power consumption is smaller than electric power consumption in the first mode and in which the display panel is turned off. The controller causes the display panel to display the reading image in response to restoration from the second mode to the first mode.

An MFP establishes a first communication link L1 by receiving an activation command and sending an OK command. The MFP receives first target data from a portable device by using the first communication link. The MFP generates second target data by processing the first target data. After receiving the first target data, the MFP disconnects the first communication link. The MFP establishes a second communication link by receiving the activation command and sending the OK command. The MFP sends the second target data to the portable device by using the second communication link.

An information processing device 110 that performs processing according to a set value represented by device setting information 121 includes an NFC unit 115 that stores set value information representing an update set value for updating the device setting information 121 and a CPU 111 that detects status of the information processing device 110 when the set value information has been stored in the NFC unit 115 and does not incorporate the set value information into the device setting information 121 when the status of the information processing device 110 is predetermined status. The NFC unit 115 is configured to be able to receive writing of the set value information thereto even when power of the information processing device 110 is off.
