RFID stands for radio frequency identification. It is a really haps technology with great marketing upside. If you have a phone that is RFID enabled and walk by a pastry shop with tarts fresh out of the oven, you might get a special alert. “Hot apple tarts.” If you don’t pay attention and continue walking the shop may ping you with a coupon to slow you down. (Nuisance? Perhaps. Smart? Very.)
Checkin (a term that foursquare would like to own) is a manual geolocation application that allows your followers on foursquare to know where you are. If you checkin to Mary Carrol’s Irish pub on St. Paddy’s Day, your friends can find you. If Mary’s Carrol’s knows you have lots of friends, they’ll be smart to encourage you to checkin. Should you decide upon stealth mode, don’t do it.
These services subscribe to the marketing view that where you are is more important than what websites you visit. Don’t get me wrong, visiting websites is a directional indicator of interest, but feet on premise or near prem is a big driver of da monies. And thanks to social media apps like foursquare, gowalla, loopt, etc. we marketers have new exciting mobile toys to play with. Peace!
