Fast food chains use apps to track customers' location for faster service.

McDonald's and Chick-fil-A are using geofencing technology to track the locations of customers who place mobile orders, allowing staff to start preparing their meals when they are close to the restaurant. This reduces wait times and ensures that the food is still hot and fresh when customers arrive. McDonald's is currently piloting this feature, while Chick-fil-A is rolling it out this summer. The fast-food industry is adapting to the growing trend of off-premise consumption, with more people ordering food online or for take-out.
