A method for controlling a printer to print on a recording medium having a non-contact tag by a processor of the printer is provided. The method comprises placing the recording medium on a placement area of the printer; wireless reading, from the non-contact tag, a plurality of pieces of identification information each for identifying a specific image; detecting whether any one of a plurality operation buttons provided on the printer has been pressed by a user, wherein the pressed operation button is corresponding to one of plurality of pieces of identification information; acquiring, from a storage device provided in the printer, the specific image corresponding the one of plurality of pieces of identification information selected by the pressed operation button; and printing the specific image on the recording medium.

A wireless tag communication device includes an antenna, a first maximum value acquiring unit, a second maximum value acquiring unit, a first minimum value acquiring unit, a second minimum value acquiring unit, and a polarization direction determining unit. The wireless tag communication device acquires, for each of n wireless tags provided on a sheet, a maximum value M1(k) of a received power intensity of the wireless tag when the radio wave is transmitted from the antenna to the sheet in a first polarization direction; acquires, for each of the wireless tags, a maximum value M2(k) of a received power intensity of the wireless tag when the radio wave is transmitted from the antenna in a second polarization direction that is different from the first polarization direction; acquires a minimum value m1 of M1(k); acquires a minimum value m2 of M2(k); and determines the polarization direction along which one of m1 and m2 that is not smaller is acquired as the polarization direction of the radio wave transmitted to the sheet.

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.

A system is described to create customized unique identification (UID) codes combined with customized printable optical or NFC sensors and to combine these unique sensors and unique IDs with unique environmental events, traceability, unique data from cell phones (including geolocation) and person-specific unique indicators such as biomarkers to create completely unique, low cost and proprietary printable genomic and environmental blockchain sensor networks for the Internet of Things (IoT), counterfeit identification, healthcare, pharmaceutical applications and small payment transactions worldwide.

An information processing apparatus transmits a login request for logging into an external device to the external device, based on a short-range wireless communication being established between the information processing apparatus and the external device in a state where an application is operating in a background state on the information processing apparatus.

Provided is an electronic device that increases operability when writing information (for example, unique user information) that allows writing to a wireless tag from the outside. The electronic device of the present disclosure includes a storage device that stores first registered information; a wireless tag that stores second registered information; and a system-control unit that updates contents of the second registered information based on the first registered information; wherein the system-control unit updates contents of information other than information that allows writing when there is writing to the wireless tag from the outside.

An image forming apparatus includes a reading unit that reads data stored in an activity amount meter, at least one of an image forming unit that forms an image on a recording medium and an image reading unit that reads the image, a display unit that displays an option to be selected such that the display unit receives a use instruction of a function that is selected, and a sending unit that sends the data stored in the activity amount meter and read by the reading unit. The display unit receives the use instruction even when the sending unit is sending the data stored in the activity amount meter and read by the reading unit.

An information inputting apparatus includes: a circuit substrate configured to communicate with an information terminal through Near Field Communication; a placement surface on which the information terminal is to be put, the placement surface facing the circuit substrate; an operation unit disposed adjacent to the placement surface, the operation unit having an operation surface parallel to and protruding further than the placement surface; and a protrusion disposed between the placement surface and the operation unit, the protrusion having a height equal to or higher than a height of the operation surface at which the operation unit reacts.

There is provided an information processing apparatus and a control method thereof. The information processing apparatus and a control method acquires user information from an external apparatus by using near field wireless communication, determines how to handle the acquired user information according to a type of a screen displayed by a display unit. For example, when the displayed screen is an authentication screen, authentication processing is executed by using the acquired user information.

According to an embodiment, an image forming apparatus includes a sheet conveyance unit that is configured to transport a print medium along a conveyance path. An antenna is configured to emit radio waves towards a predetermined portion of the conveyance path. A controller is configured to control the antenna to emit the radio waves towards the predetermined portion with a polarization direction set according to a type of the print medium being transported by the sheet conveyance unit. The print medium may have, for example, one or more wireless tags thereon or therein.
