An On-screen button format has the following set of parameters: colour, size, text font characteristics, and relative positions of the text and the picture. Users can modify button formats on the basis of ready-made styles. These styles designate the relative positions of the picture and the text on a programmable button.

The on-screen button format is used in the Menu and Draft menu directories, in the Payment methods directory, and in the POS terminal operating modes directory.

The On-screen button formats directory is used to manage the formats of buttons that are displayed on POS terminal screens.
