摘要： A method for detecting fingerprints implemented in an electronic device includes detecting whether a display device is being pressed by at least one finger of a user according to signals of a pressure sensing device. If the display device is being pressed by the at least one finger of the user, controlling a fingerprint acquiring device to acquire fingerprint images of the at least one finger of the user and controlling a positioning device to acquire location information of the electronic device. The fingerprint images of the at least one finger of the user and the location information of the electronic device can be uploaded by the electronic device to a fingerprint database for fingerprint recognition.

摘要： A communication device includes a positioning unit and a communication unit. The positioning unit obtains positioning information of the electronic device when the electronic device is turned on or off. The communication unit sends the positioning information to a base station of a communication operator of the electronic device at preset time intervals. Whether the base station has received the positioning information is determined. If the base station has not received the positioning information, the communication unit increases a transmission power for transmitting a signal and sends the high-frequency signal carrying the positioning information of the electronic device to a communication satellite.
