A system for reading data from a plurality of chips each comprising an RFTID tag, the system comprising: a chip tray having an area which can accommodate a 5 plurality of chips, an antenna including the area in its communication range, a database which can register the plurality of chips as data, 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 10 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 15 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.
