But not only, in addition to GPS, mobile phones Japanese also use other techniques for locating useful in areas where it is under cover, the GPS signal is not funzionae: train stations, for example, once you pass the entrance , the RFID chips of mobile phones provide to send an email with details of where the phone is located.
