Pinpoint is a tracking system for bicycles in NYC.
HOW IT WORKS
Passive RFID tags are embedded within the bike frame. These unpowered tags are read by the E-ZPass NY transponders that are along many major roads, sending the coordinates and timestamp to the cloud, where it is represented on their own private map.
To extend the search range beyond areas with transponders, phones with the app installed also record the location data of any tags they encounter.
