The pairing method of first and second devices each having a communication function using a millimeter wave band, includes: determining, by the first device, whether or not the a security code of the second device has been registered; when the first device determines that the security code of the second device has been registered, transmitting, by the first device, an activation command instructing the second device to perform millimeter wave band communication, a device ID, and the security code of the second device to the second device through RFID communication; and when the first device receives a message indicating that the second device is ready for millimeter wave band communication from the second device, activating, by the first device, an element for performing communication using the millimeter wave band.
