A reading apparatus includes a communication unit, a scanner, and a processor. The communication unit communicates with a wireless tag provided on paper. The scanner scans the paper. The processor acquires data from the wireless tag through the communication unit, acquires an image from the paper by using the scanner, and generates a file in which the data is embedded in the image as hidden characters.

A method of automatically displaying a predetermined set of print attributes of a print job, the method including receiving an image of a first printed sheet, the first printed sheet including one or more at least partial machine-readable codes, the one or more at least partial machine-readable codes encoded with data related to the predetermined set of print attributes, decoding the data from the one or more at least partial machine-readable codes, determining if the data includes all of the print attributes in the predetermined set of print attributes, and if the data includes all of the print attributes in the predetermined set of print attributes, displaying the data using augmented reality (AR) over the first printed sheet.

A sheet processing apparatus for processing sheets each with a wireless tag, includes a roller, a wireless tag reader/writer, and a controller configured to control the roller to convey a first sheet with a first tag along a path, control the reader/writer to acquire first strengths of radio signals received from the first tag during the conveyance and second strengths of radio signals received from wireless tags of sheets not being conveyed, determine a threshold value of signal strength for distinguishing a wireless tag being conveyed from wireless tags not being conveyed based on the first and second strengths, and control the roller to convey a second sheet with a second tag and control the reader/writer to write to the second tag when a strength of a radio signal from the second tag is greater than or equal to the threshold value.

An image forming apparatus includes a printing unit, a reversing unit, a writing unit, and a control unit. The printing unit forms an image on a sheet-like medium to which a wireless tag is attached. The reversing unit reverses a front and back of the medium. The writing unit writes data on the wireless tag. The control unit controls the reversing unit so that the medium is reversed twice upon the writing of data on the wireless tag failing and controls the printing unit so that an image indicating that the writing of data fails is formed on the medium reversed twice.

According to one embodiment, there is provided an image forming device that prevents write information from being incorrectly written to a non-target RFID tag. The image forming device according to the embodiment includes: a placement unit, a wireless tag communication unit, and a conductor. A sheet provided with a wireless tag can be placed in the placement unit. The wireless tag communication unit can write information to the wireless tag provided on the sheet. The conductor is provided in the placement unit and hinders communication between the wireless tag communication unit and the wireless tag.

An image forming apparatus includes a wireless tag communication device to write data to, and read data from, a wireless tag attached to a sheet. An image forming device in the apparatus is configured to form an image on the sheet. A controller in the apparatus is configured to determine whether a writing of data to a wireless tag was successful based on a notification from the wireless tag communication device and generate investigation support information if the writing was not successful and control the image forming device to form an investigation support image corresponding to the investigation support information if the writing was not successful.

An image forming apparatus includes an image reading unit configured to read an image formed on an object to be scanned, an image forming device configured to form an image on a printing object, a first processing unit configured to perform short-range radio communication to perform at least one of data reading operation from an information storage unit mounted on the object to be scanned and data writing operation to the information storage unit, and a second processing unit configured to perform short-range radio communication with the information storage unit mounted on the printing object to perform at least one of the data reading operation from the information storage unit and the data writing operation to the information storage unit. In the image forming apparatus, each one of the first processing unit and the second processing unit is configured to perform the short-range radio communication using a same antenna unit.

The invention relates to devices intended for reading and recognizing printed or written characters or for recognizing patterns, e.g., fingerprints, for document verification/authentication (e.g., passport verification). A portable hardware-software complex (PHSC) includes a housing with a visible spectrum camera and a fingerprint scanner. The housing includes a power supply unit and a processor. On the housing from the fingerprint scanner side there is a display, and on the back side of the housing there is a visible spectrum camera with two or more sources of visible spectrum radiation and UV radiation, installed to illuminate the visible spectrum camera field of view. On the back side of the body there is an infrared camera and one or more sources of infrared radiation, for illuminating the field of view of the infrared camera.

A conductive sheet capable of preventing erroneous reading and writing is provided. The conductive sheet according to one embodiment is configured to be positioned between a sheet tray of an image forming device and a sheet. The conductive sheet includes a base layer and a double conveyance prevention structure. The base layer comprises a conductive material positioned to overlap with a wireless tag of the sheet. The double conveyance prevention structure is coupled to or defined by the base layer. The double conveyance prevention structure is configured to prevent conveyance of the conductive sheet by the image forming apparatus when the conductive sheet overlaps the sheet in the sheet tray.

A sheet conveyance device includes a roller by which a sheet having a wireless tag is conveyed along a path, a communication device configured to transmit a radio signal to the wireless tag and receive a response signal therefrom, and a processor configured to repeatedly perform a process of controlling the roller to convey a sheet along the path while controlling the communication device to transmit the radio signal to a wireless tag of the sheet using a transmission power that is different in each repeat, and acquire a strength of the response signal from the wireless tag, and specify a minimum strength of the response signal that has been acquired in the repeated process, the minimum strength being equal to or greater than a threshold, and set a transmission power that has been used when the minimum strength has been acquired as a reference strength of the radio signal.
