When Minimize is selected, it minimizes the number of bills dispensed, and when more than one cassette has the same bill denomination, one cassette is depleted before the other cassette is used.

For example:

A three (3) cassette cash dispenser has 1 cassette with $10 bills in cassette A and $20 bills in cassettes B and C. A request for $150 dollars would be filled with 1 bill from cassette A and 7 bills from from cassette B unless cassette B was out of money, in which case the bills would come from cassette C.

When Minimize EW is selected, the terminal rotates which cassette with the same denomination is used, by transaction, because picking multiple notes from one cassette is quicker than picking the same number of notes from multiple cassettes. After every restart, the terminal will start its rotation from the same cassette.

Examples:

1) Terminal 1 has two cassettes (A and B) with the same denomination. The first transaction after a terminal restart will always use casssette A. The second will use cassette B and subsequent transactions will continue to alternate between the two cassettes.

2) Terminal 2 has four cassettes (A, B, C, and D) with the same denomination. The first transaction after a terminal restart will always use cassette A; the second, cassette B, the third cassette C, the fourth cassette D, and the fifth would restart the pattern at cassette A.
