摘要： According to an embodiment, a wireless tag reader apparatus includes a reader and a processor. The reader acquires the position information of the wireless tag based on the phase difference between the carrier waves and the response waves transmitted and received by the first antenna and the second antenna. The processor determines whether or not the wireless tag is in the predetermined zone based on the position information acquired by the reader.

摘要： A wireless tag communication device includes a directional antenna, a communication control circuit configured to communicate with a wireless tag through the directional antenna, a camera positioned such that a direction along which a signal strength of the directional antenna is maximized and a shooting direction of the camera coincide with each other, and a controller. The controller is configured to estimate a tag direction where the wireless tag exists, estimate a position of the wireless tag communication device, estimate a position of the wireless tag based on the estimated tag direction and the estimated position of the wireless tag communication device, and control a display to display a first image captured by the camera and a second image showing an explicit area containing the estimated position of the wireless tag.

摘要： A commodity container includes a main body with a container space and a radio frequency reader with a communication range that covers an opening of the container space. The radio frequency reader outputs tag information based on a radio frequency signal from a wireless tag and outputs time variation information indicating a time variation of the radio frequency signal. A registration device is attached to the main body and includes a communication interface to receive the tag and time variation information, and a processor configured to determine a time variation in a positional relationship of the wireless tag and the radio frequency reader based on the time variation information and update a commodity registration list based on the determined time variation of the positional relationship.

摘要： A wireless tag communication device includes an antenna, a communication control circuit, a camera, a sensor, and a processor. The antenna has directivity. The communication control circuit communicates with a wireless tag via the antenna. The camera captures an image in which a direction in which the directivity of the antenna is maximized coincides with a capturing direction. The sensor detects brightness in a first image captured by the camera. The processor calculates a detection position of a wireless tag as a search target in the first image and displays on a display the first image and a second image in which the first image is masked with a mask density according to a sensor value detected by the sensor in an area other than an explicit area with the detection position of the wireless tag as a base point.

摘要： According to an embodiment, a search device includes an antenna having directivity, a communication unit, a determination unit, an imaging unit, and a display unit. The communication unit that wirelessly communicates with a search-target wireless tag using the antenna. The determination unit is configured to determine a relative position of the wireless tag with respect to the antenna based on a state of communication between the communication unit and the search-target wireless tag. The imaging unit that obtains an image of an imaging range defined as a direction of orientation of the antenna. The display unit is configured to display a screen on which a guide image for bringing the antenna close to the position determined by the determination unit is superimposed on the image obtained by the imaging unit.
