RFID Phones unlock doors
July 26, 2004
Creative use of new technology: Shin'ichi Konomi reports from Japan:
Hayakawa Realty starts selling new condos whose doors can be opened by RFID-powered mobile phones.The idea of sending the plumber / the cable guy / a friend an SMS message with a one-time key to your house can certainly spur a raft of creative applications (and loads of potential problems). Still - a cool idea!
It is similar to using RFID cards to open doors but there is a fundamental difference because RFID tags embedded in mobile phones can easily be connected to the network. Keys can be digitally copied over the network. Also, one could issue a temporary key that expires after a specified period of time.
