Salesforce Marketing Cloud (SFMC) is a provider of digital marketing automation as well as analytics software and services. It automatically and in real time populates your SFMC with subscribers from your WiFi users. 

You have control over the user data that you want sent to SFMC. If a WiFi user later changes their marketing preferences in the ‘MyData’ portal, those changes will be reflected in SFMC.
