Methods and a system for interface extensions

Abstract:

A base transaction User Interface (UI) is provided that provides transaction processing for transactions at transaction terminals. The base UI can be customized through independent and decoupled customization/extension files, which provide specific UI customizations for UI screen content, UI screen styles, UI screen views, UI screen workflows, and UI screen resource functionality. Customizations or extensions are achieved without modifying the base UI. The customizations or extensions are dynamically obtained during execution of the base UI from the corresponding files and processed by the base UI as user-defined custom overrides.
