Abstract: In an example implementation according to aspects of the present disclosure, a method may include determining a transactional state of a point of sale (POS) system and, upon determining the transactional state, when the POS system is not in transactional use, automatically switching a display panel of the POS system from a first position to a second position. As an example, while in the second position, the POS system displays an advertisement on the display panel.

Abstract: In an example implementation according to aspects of the present disclosure, a method, system and computing device for supporting conditional firmware images. A set of conditions may be received, wherein the conditions are based on characteristics of a computer. A set of indications corresponding to displayable images may be received. The set of conditions may be compared against a system clock of the computer. Responsive to the comparing, a section of the non-volatile memory may be set to one of the set of indications based on the comparing. One of the displayable images corresponding to the section may be displayed.
