A decentralized ordering system allows a customer to track order status from a centralized order status system by providing a single, easily remembered identifier (such as a telephone number) without having to log in and without having to specify which local system is handling the customer's order. The central system communicates with each local system to obtain order status information. The central communication function handles all login and authentication requirements on the local systems, if necessary, and reformats the order status data, if necessary, to a common format for storage at the central location. The system also may notify the customer, via telephone, text message, instant message or electronic mail, whenever the order status changes or when the order status changes to a predetermined condition (such as “out for delivery”).
I know about software patents but what’s the point when somebody can achieve the exact same functionality from the user’s perspective using totally different code. Just seems like a waste on a patent lawyer.
It’s not useful, as it doesn’t always reflect reality so it’s just a bunch of loading bars to manage customer expectation. Ask the domino’s subreddit
