RFID has some of the significant properties you are looking for. I don't know if it has all of them because I've just about exhausted all my knowledge of RFID and don't know any details of the actual problem you are trying to solve. But RFID is deployed at scale and "everywhere." Probably because the technology doesn't depend on protocols developed for other uses (e.g. IP). Good luck. |
