Provided herein are methodologies, systems, apparatus, and non-transitory computer-readable media for configuring a graphical user interface of an electronic display device for enabling preauthorized payment of products or services using distributed processing. A customer may interact with a kiosk or terminal to identify themselves and initiate the process for dynamically computing an active preauthorization limit. Items may then be added to the customer's balance at various point of sale terminals or scanning locations within the facility. Total cost of the items is compared to the active preauthorization limit. Once the customer is finished shopping, a GUI can present them with an authorization screen showing their shopping balance and requesting authorization. The user can interact with the GUI to approve the total via the GUI without the need to produce their card or payment method at checkout.
