Method for storing redundant data on dongles in gaming machine, involves storing generated index information with user information, where data of index space and user information of non-exchanged dongles are copied on exchanged dongles

摘要

The method involves providing three dongles that are in an operative connection with a common base system provided with a unique identifier. The dongles are randomly or sequentially numbered, and the base system is provided with the identifier, which is stored as identification on each dongle. An internal index space of each dongle is initialized with an initial value. The generated index information is copied to each dongle and stored together with user information. The data of the index space and the user information of non-exchanged dongles are copied on exchanged dongles.
