Amazon’s palm-reading tech is gonna be provided when you are entering sports stadiums or music venues. And it can be extended to any other event, of course.
So we are making it more simple for entering, they claim.
But also more simple to track us via big data approaches. Of course, Google and Apple know already all the time where we have been. I assume that most people have the GPS service of their mobile phones switched on. Amazon is there a bit behind as they „only“ know our shopping habits.
