An electronic device includes a display module, an NFC (Near-field Communication) module, a verification module and a control module. The display module is disposed on a first surface of the electronic device. The NFC module includes an antenna unit. The antenna unit is configured to transmit and receive a wireless signal from an outward direction of the first surface. The verification module is disposed on a second surface of the electronic device. The verification module is configured to generate an identification input data according to an operation of a user. The control module is configured to drive the verification module to generate the identification input data when the NFC module receives an identification requirement data, and configured to determine whether the identification input data is valid.
