One of the most interesting scenes in the movie 'Minority Report' is when Tom Cruise enters a store. The video screen in front of him immediately addresses him by name and asks how enjoyed his last purchase. Bluekulu has developed a solution that provides a similar experience.
The bluetooth id built into most phones allows each phone to be uniquely identified via a bluetooth scan. This data can be used to launch a new video on a screen.
Bluekulu can provide a point of sales scanner that will monitor bluetooth id's as people move through the check out area. The generated data can be linked to sales information and a decision matrix generated that changes content on screen in the store the next time that phone is found in the store.
