Near field communication tag reader, mobile terminal for interworking with the reader, and operating method thereof

摘要

A mobile terminal acquires an item group identifier and an item identifier from a near field communication tag reader which recognizes an item group identification tag and an item identification tag. The mobile terminal acquires item group information related to an item group corresponding to the item group identifier, and extracts information related to an arrangement location of an item corresponding to the item identifier from the item group information. The mobile terminal checks whether or not the item has been correctly arranged based on the arrangement location and an identified location of the item corresponding to the item identifier, so as to display information indicating that the item has been incorrectly arranged.
