In some embodiments, a wireless pairing method involves a touchscreen on a wireless host device combined with a switch on a wireless stylus device. The wireless pairing method uses the time-coincidence of a touch on the host device screen with the detection of a tip switch press on the stylus device as a mode of out-of-band communication to authenticate a pairing of the devices. In such embodiments, a user presses a tip portion of the stylus device against a pairing spot on the host device surface; the wireless devices then form a bonded pair if the touch and/or release of the tip portion of the stylus device with respect to the host device surface are within a pre-determined time co-incidence window of the detection by the host device of that touch and/or release of the tip portion of the stylus device.
