Pairing method and pairing system

A method for pairing two devices (20, 30; 40, 50; 80, 90) and a pairing system (1) are provided. Each of the devices (20, 30; 40, 50; 80, 90) may be configured to receive power from a power supply device (10) and comprise a memory (23, 33; 43, 53; 83, 93). The method includes detecting non-contact power supply from the power supply device (10) to each of the two devices (20, 30; 40, 50; 80, 90), receiving the non-contact power supply and performing pairing setting of the two devices (20, 30; 40, 50; 80, 90) and storing identification information of one of the two devices (30; 50; 90) in the memory (23; 43; 83) of the other device (20; 40; 80).
