Abstract: A networked application system includes a plurality of user front-end devices each operating a user front-end application and a plurality of provider front-end devices each operating a provider front-end application. A networked back-end operates to interface with the user front-end application of each of the plurality of user front-end devices and with the provider front-end application of each of the plurality of provider devices. A user of the user front-end application is uniquely identified by a user ID. A goods and services provider is uniquely associated each provider front end device and the provider site where the provider front end device is operated is known. The networked back-end operates to monitor each of the plurality of user front-end devices, and each of the plurality of provider front-end devices in order to detect triggering events such as interactions between user device users and a provider sites.
