Um ... it doesn&#x27;t work exactly like that. If you leave your phone&#x27;s WiFi turned on, you and your friends <i>will</i> be using Nomi sometime soon (so exciting, amiright?)! You see, the store&#x2F;eatery&#x2F;prison&#x2F;airline&#x2F;casino&#x2F;whatever just puts the Nomi WiFi access point on their premises, and when you come in your phone tries to connect to it, and BLAMO, it harvests your MAC address. Now they have a unique identifier for &#x27;you&#x27; (your phone&#x27;s MAC), and they can keep track of how many times you go into the place, where else you like to go, what sections you like to browse (just a few more of the gadgets scattered in the store), if you&#x27;ve been to their marketing events, etc. etc. etc. Oh hey, since it harvests your MAC address, they can also tell who manufactured your phone. &#x27;you&#x27; have an apple phone? Sweet! We&#x27;ve got ourselves a (probably) high-end customer.<p>Welcome to the future :(
