Abstract: A mobile system includes an electronic device and a flip cover device. The electronic device communicates with an external device through a near field communication (NFC) scheme. The flip cover device includes a back side cover, which is installed on a back surface of the electronic device to surround the back surface of the electronic device, a front side cover, which selectively covers a front surface of the electronic device and includes a display module, and a connector device, which connects the back side cover and the front side cover. The flip cover device receives power and information data from the electronic device through a first electromagnetic wave emitted from the electronic device and displays the information data on the display module using the power.
