An electric device attachable to option boards and a method for controlling the same. The electric device includes option connectors for connecting to the option boards, a power unit which supplies a voltage for operating a circuit on the option boards, readers/writers which read information for determining whether or not the option boards are compatible with the electric device based on RFID tags added to the option boards, and a backup control portion which determines whether or not the option boards are compatible with the electric device based on the information read by the readers/writers. When the backup control portion determines that the option boards are compatible with the electric device, the power unit supplies the voltage to the circuit. When the backup control portion determines that the option boards are not compatible with the electric device, the power unit prevents the supply of the voltage to the circuit.
