Multiple Fast Cash Buttons
(Maitre'D 2003, from Service Pack 10 and later versions of 2003)
You can use Fast Cash buttons lower then the check total multiple times.
Every time a Fast Cash button is touched, if the button is not enough
to close the bill, this amount will be cumulated with the next Fast Cash
button. When the total cumulated amount is enough to cover the check total,
the payment will be accepted.

To be able to multiply Fast Cash buttons, under the C:\Posera\MaitreD\Data
directory, in the [Miscellaneous] section of the Bo.ini file, add the
following configuration key and value:
MultipleFastCashKey=True
