The CA$H-CART was designed for placement in convention centers and other inside venues.  This unit is ideal for weekend events.  It can be rolled into place, locked down, plugged in , and be ready for use in minutes.  At the event conclusion it is simply rolled out.  The unit shown in the picture is an NCR 5670. 

These units have been placed at convention centers, indoor arenas, and in seasonal venues.  The units, because they can moved easily, can be stored in a closet or storage room when not in use.  As an example, the unit shown above is used at an outdoor amphitheater.  It is kept in the box office and rolled out for each event.
