A multiple integrated machine system ("MIMS") capable of performing as multiple digital machines. The MIMS comprises multiple elements controlled by one operating system. Each element is different. Each element includes hardware and software and can perform as part of one machine. An element grouping control unit is provided. Upon receiving a first machine selection, the control unit automatically, operatively connects elements in a first combination forming a first machine. Upon receiving a second machine selection, the control unit automatically, operatively connects elements in a second combination forming a second machine. The first and second combinations differ. Multiple subgroup function control units are provided. Each subgroup function control unit corresponds to either the first or second machine selecting one or more functions to be performed by the respective machine. Four types of MIMS (desktop, kiosk, mobile and hospitality) are disclosed, with multiple machines being selectable for different functions.
