a stage on which the item can be placed;
one or more antennas movable between first and second positions;
a camera facing the stage; and
a controller configured to:
control the camera to capture images and detect an object therein,
control the antennas to transmit radio waves to a wireless tag and move the antennas, wherein the transmitting and the moving are repeated while the antennas move from the first position to the second position during a tag reading period,
acquire tag information from response waves transmitted by the wireless tag in response to the radio waves,
based on the captured images, determine whether the object has moved during the tag reading period, and
upon determining that the object has moved during the tag reading period, issue a notification.
