Conditional location-based reminders

Architecture that enables conditional location-based notifications. One or multiple factors (filter criteria) can be considered, and triggering of a notification can be based on some or all of the factors. Those factors can be static (e.g., time based) or dynamic (e.g., a previous user location) and extend the ability to filter unnecessary notifications, and thus, increase user satisfaction. The filter criteria can include checking user back balance, and calendar as prerequisites to sending a notification.
