Abstract
A reading system includes an evaluation value acquirer and a determining processor. The evaluation value acquirer is configured to acquire, with regard to a reading device configured to perform wireless communication with an electronic tag attached to each of one or more items by using a radio wave as a medium to read item information on each of one or more items, an evaluation value about at least one of: the number of times; a time interval; or a frequency, of reading the item information for each of at the one or more items. The determining processor is configured to determine, for each of the one or more items, whether or not each of the one or more items is an object to be read based on a change in the evaluation value over time.
