The present invention relates to an ordering system that allows a mobile device to connect to the ordering system through an on-site wireless network access device and to place orders. A mobile device, such as a smartphone or a tablet, is connected to a service provider's wireless network access point to confirm the customer is physically on-site. The ordering system provides an ordering interface to the web browser running on the mobile device. A customer enters his order through the ordering interface on the mobile device. The order is sent back to the ordering system for processing. The ordering system processes the received order and sends status notifications to the mobile device to notify the customer that his order is ready.
