Methods and a system for interface extensions

A method, comprising:

• providing a transaction user interface (UI) for a transaction manager as a set of default UI screens provided with default screen sequences, default screen content, default screen layouts, default screen styles, and default screen option functionality, wherein the transaction UI comprises a base and overridable source code;
• providing customizable override files that can be customized with override data that overrides for the default screen sequences, the default screen content, the default screen layouts, the default screen styles, and the default screen option functionality;
• processing the transaction UI for a transaction at a transaction terminal;
• and
• dynamically overriding, by the transaction UI, one or more of:
• the default screen sequences, the default screen content, the default screen layouts, the default screen styles, and the default screen option functionality by dynamically interpreting and processing the override data without modifying the base and overridable source code associated with the transaction UI.

A system, comprising:

• a transaction terminal comprising a processor and a non-transitory computer-readable storage medium:
• the non-transitory computer-readable storage medium comprising customization files and executable instructions for a transaction User Interface (UI), wherein the transaction UI comprises a base and overridable source code;
• each customization file comprising text and instructions for custom overrides to the transaction UI;
• the transaction UI executed by the processor from the non-transitory computer-readable storage medium causing the processor to perform processing comprising:
• dynamically obtain the customization files upon initiation on the transaction terminal during a transaction being processed on the transaction terminal;
• and
• dynamically implement the custom overrides during the transaction to change default content, default screen sequences for screens rendered on a display of the transaction terminal, default screen styles, default screen layouts, and default screen option functionality that are provided by the transaction UI without modifying the base and overridable source code associated with the transaction UI by dynamically interpreting and processing each customization file.
