547.9—What are the minimum technical standards for Class II gaming system accounting functions?

This section provides standards for accounting functions used in Class II gaming systems.
(a) Required accounting data. The following minimum accounting data, however named, shall be maintained by the Class II gaming system.
Title Description
(1) Amount In The total value of all financial instruments and cashless transactions accepted by the Class II gaming system. Each type of financial instrument accepted by the Class II gaming system shall be tracked independently per financial instrument acceptor, and as required by applicable requirements of any Commission and tribal gaming regulatory authority regulations governing minimum internal control standards.
(2) Amount Out The total value of all financial instruments and cashless transactions paid by the Class II gaming system, plus the total value of attendant pay. Each type of financial instrument paid by the Class II Gaming System shall be tracked independently per financial instrument dispenser, and as required by applicable requirements of any Commission and tribal gaming regulatory authority regulations governing minimum internal control standards.
(b) Accounting data storage. If the Class II gaming system electronically maintains accounting data:
(1) Accounting data shall be stored with at least eight decimal digits.
(2) Credit balances shall have sufficient digits to accommodate the design of the game.
(3) Accounting data displayed to the player may be incremented or decremented using visual effects, but the internal storage of this data shall be immediately updated in full.
(4) Accounting data shall be updated upon the occurrence of the relevant accounting event.
(5) Modifications to accounting data shall be recorded, including the identity of the person(s) making the modifications, and be reportable by the Class II gaming system.
(c) Rollover. Accounting data that rolls over to zero shall not corrupt data.
(d) Credit balance display and function. (1) Any credit balance maintained at the player interface shall be prominently displayed at all times except:
(i) In audit, configuration, recall and test modes; or
(ii) Temporarily, during entertaining displays of game results.
(2) Progressive prizes may be added to the player's credit balance provided:
(i) The player credit balance is maintained in dollars and cents;
(ii) The progressive accounting data is incremented in number of credits; or
(iii) The prize in dollars and cents is converted to player credits or transferred to the player's credit balance in a manner that does not mislead the player or cause accounting imbalances.
(3) If the player credit balance displays in credits, but the actual balance includes fractional credits, the Class II gaming system shall display the fractional credit when the player credit balance drops below one credit.
