Currency Handling System Offline Foreign Currency Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Gaming machines face challenges in managing foreign currencies due to communication errors with the management server, leading to uncertainties in exchange rates and potential disadvantages for players and owners, as they cannot accurately handle or monitor foreign currencies during offline states.
Innovation Solution
A currency handling system with a controller that limits the usage of foreign currencies while allowing local currencies during communication errors, includes a storage unit for exchange rates and a display device to inform users of limitations, and updates exchange rates once communication is restored.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the gaming machine accepts a variety of foreign currencies and uses real-time exchange rates from the management server, then the currency handling capability and accuracy are improved, but the system reliability deteriorates when communication errors occur
Solution Approach 1:
The gaming machine stores exchange rates in a storage unit beforehand, so when communication errors occur, the machine can continue to operate using the pre-stored exchange rates. This preliminary action ensures that the system maintains reliability during communication outages while still supporting multiple foreign currencies.
2Reliability
If the gaming machine limits foreign currency usage during communication errors, then the risk of disadvantage to players is reduced, but the ease of operation deteriorates
Solution Approach 1:
The display unit provides feedback to users about the communication status and currency usage limitations. When communication errors occur, the system informs users that foreign currency usage is limited and local currency usage is recommended, helping users understand the situation and adjust their behavior accordingly.
3Loss of information
If the gaming machine displays exchange rates continuously, then information transparency is improved, but the device complexity increases due to continuous communication requirements
Solution Approach 1:
The display of exchange rates is dynamic rather than static. The system automatically updates the exchange rate display when communication with the management server is successful, and hides or disables the display when communication errors occur. This dynamic behavior maintains information transparency when possible while reducing communication complexity when necessary.

AI summary
An object of the present invention is to provide a currency handling system which makes it possible to decrease a risk of dealing with foreign currency at the time of the occurrence of a communication error in a case in which a currency reading device capable of accepting a variety of currencies including a foreign currency is used while the currency handling system is connected to a management server through a communication line. A currency handling system 100 is connected to a casino management system 2 through a network 3, and includes a currency reading device 201 which is capable of accepting a variety of currencies and a PTS terminal 700. The PTS terminal 700 causes a process which limits usage of a foreign currency but allows usage of a local currency in the currency reading device 201 to be performed in a case (offline state) in which an error occurs in communication with the casino management system 2.
