Define the new state letter or code in the NDC configuration initialization file. Before writing a single line of code, you

States define the logical workflow of the ATM application. Each state is designated by a three-character alphanumeric ID (e.g., A01 , B22 ) and a specific State Type letter (e.g., State A for Card Read, State B for PIN Entry). Each state processes a specific action. It evaluates user inputs or hardware responses. States define the logical workflow of the ATM application
