## Abstract

A management system for a gaming chip is equipped with an RFID tag, wherein the RFID tag stores identification information including a tag ID assigned at the time of manufacture of the RFID tag and a chip ID assigned at the time of manufacture of the gaming chip. The management system includes an antenna and a chip tray reader/writer that read identification information from the RFID tag of the gaming chips that exist within a reading range; a table verification device that controls the chip tray reader/writer. The table verification device causes the chip tray reader/writer to repeatedly perform a first reading, in which the chip ID is read without reading the tag ID, and, when a new chip ID was read in the first reading, cases the chip tray reader/writer to perform a second reading in which the tag ID is read.
