Abstract
The present application provides a system which includes a registration unit which reads data from the chip located within the communication range at a first timing via the antenna, and registers the data in the database, an updating unit which reads data from the chip located within the communication range at a second timing which occurs later than the first timing via the antenna, and updates the database based on the data read, a determination unit which reads data from the chip located within the communication range at a third timing occurring later than the first timing via the antenna, and determines whether or not data of a chip other than the chip read is registered in the database, and a communication unit which, when it is determined by the determination unit that data of a chip other than the chip read is registered in the database, communicates individually with each chip other than the chip read.
