Description

CROSS-REFERENCE OF RELATED APPLICATIONS This application claims the benefit of Patent Application No. 2020-176900, filed in Japan on October 21, 2020, the contents of which are hereby incorporated by reference. TECHNICAL FIELD The present invention relates to a casino system applied to casinos that use casino item, a casino item usable in casinos, and a method for manufacturing casino item. BACKGROUND TECHNOLOGY Casino items used in casinos requires a high level of security, and casino items should be strictly managed. For example, casino items are manufactured in a manufacturing factory, but there is a risk of theft by malicious persons during the process of transporting the items from the manufacturing factory to the casino and using those on the floor area. There is also a risk of counterfeit casino items being used in the floor area of the casino to help players win the game unfairly. The casino items that require high security are typically gaming chips. Each gaming chip is given a unique identifier. The gaming chip contains an RFID tag, which stores the identification information. The casino system will also use a database that stores the identification information of the gaming chips. By reading the identification information from the RFID tag of the gaming chip and referring to the database at each of multiple locations in the casino that handle casino items, various security managements can be performed (see, for example, International Application Publication No. WO2008/120749). SUMMARY OF THE INVENTION PROBLEMS TO BE SOLVED BY THE INVENTION The purpose of the present invention is to enhance the security management of casino items given identification information. SOLUTION TO SOLVE THE PROBLEMS One type of casino system is a casino system in a casino that uses a casino item to which an RFID tag storing identification information is attached, and is equipped with a registration device that registers the identification information of the casino item that can be used in the casino, and a storage device that stores a list of the identification information registered by the registration device. The registration device performs an invalidation process to invalidate the registration of the identification information of the casino item when the casino item whose identification information is stored in the storage device as usable casino item meet the specified conditions. With this configuration, the registration of casino item that meet the predetermined conditions for invalidating the registration can be invalidated, and the invalidation process can be performed for casino item that were once registered but later became in a state where they should not be registered. The invalidation process includes deleting the item from the list of the storage device, storing the information that the item is invalid in the list of the storage device, and further includes storing the information that the item is suspicious, needs attention, or is a candidate for invalidation in the list of the storage device. In the casino system described above, the system is further equipped with a reader that reads the identification information from the RFID tag of the casino item to be registered. The identification information of the casino item that is determined to be genuine can be registered as the identification information of the usable casino item. This configuration can guarantee that the casino item to be registered are genuine. The casino system described above, may be further equipped with a reader that reads the identification information from the RFID tag of the casino item to be registered, and the registration device may register the identification information read by the reader. This configuration can prevent incorrect registration in which the identification information stored in the RFID tag of the casino item differs from the identification information stored in the storage device by the registration device. The casino system described above, may be further equipped with a reader that reads the RFID tags of the plurality of the casino item housed in a case, and the registration device may register the plurality of the identification information read by the reader. With this configuration, the registration work can be performed quickly and smoothly. In the casino system described above, the registration device may store the identification information of the usable casino items with a flag indicating that they are usable. With this configuration, the invalidation process can be performed by updating the flag. The casino system described above, may be further equipped with a reader that reads the identification information from the RFID tag of the casino item, and the registration device may perform the invalidation process for the casino item for which the identification information cannot be effectively read by the reader. With this configuration, the registration of casino item whose RFID tag is malfunctioning
