Manufacturers of electronically generated bingo cards for electronic bingo daubers must use a computer to store the bingo cards and interface with a printer. The computer must:

(1) Retain in memory a record of transactions for a session until the operator totals, prints, and clears the transactions, even if the unit's primary power source is disrupted; and

(2) Compute a total of all transactions occurring during the current session and print out the total on request; and

(3) Maintain and control the time and date of sale and transaction number in a manner that prohibits change or resetting except by the manufacturer or qualified service personnel. Operators must retain a detailed record, supported by service documents for each service call involving a change of the time, date, or transaction number; and

(4) Secure the electronically stored bingo cards in a way that prevents an operator or player from modifying them. The system must not allow operators to exchange, transfer, refund, or modify the price of cards issued to a player in any way after the sale is made. The system must store cards on "erasable programmable read only memory" (EPROM), "compact disc read only memory" (CDROM), "write once read many" disc drives (WORM), or other systems we approve.
