RFID device based Applications... any takers ?
I had considered it strongly but decided against it because
I did some work for a company at http://www.freedompay.com which uses RFID technology similar to Mobil Speedpass for payment systems. They have embedded these devices into fob's and mini-credit-cards. The goal is for these to be used primarily for small purchases like gas, video rentals, vending machine purchases, etc.
The lack of a serious safe executing platform and networking platform in mobile computing will never allow the wet dream of having billions of users broadcast their GPS whereabouts (plus elevation and direction) to relational marketing opportunity. It will take a lot of infrastructure and a lot of years of maturation. So I don't know how long you have to wait before fetching that pulse of RFID from a block away.
Marketing purposes (data mining). You could drive around a neighborhood and find out exactly what people have.
