The invention discloses a connecting method of wireless devices, a wireless device and a wireless communication system. The method includes arranging a short-distance wireless communication NFC label reading module into a first wireless device without a display component and input component; connecting the first wireless device to a second wireless device in a wireless manner, and writing the required wireless connecting information into the NFC label reading module; allowing to the NFC label reading module to get close to the first wireless device, and allowing the NFC label reading module of the first wireless device to read the wireless connecting information from the NFC label reading module so as to allow the wireless device without the display component and input component to connect to anther wireless device conveniently and rapidly. According to the technical field, the wireless device without the display component and input component can be connected to anther wireless device conveniently and rapidly by adding one NFC label reading module only, and equipment cost of the wireless communication system is reduced greatly as compared with a wireless communication system adopting the display component and input component.
