System and method for wireless device pairing

A wireless communication method comprising:

• a first portable biometric device and a second device communicating wirelessly to initiate a pairing process between the first portable biometric device and the second device, wherein the first portable biometric device comprises a user interface, at least one sensor, and wireless communication circuitry in a unit suitable to be worn by a moving human device user;
• the first portable biometric device subsequently generating a cue to the first portable biometric device user via the user interface requesting the first portable biometric device user to validate the pairing between the first portable biometric device and the second device;
• the first portable biometric device receiving input from the user indicating the user's agreement to validate the pairing request, wherein input comprises tapping the first portable biometric device anywhere on its exterior;
• the first portable biometric device detecting the tapping using a motion sensor;
• the first portable biometric device responding to the user input by signaling the second device to complete the pairing process;
• and
• the second device and the first portable biometric device communicating to complete the pairing process, wherein the first portable biometric device and a second device are remote from each other throughout the pairing process, after which the first portable biometric device and the second device are able to recognize each other;
• and
• the first portable biometric device and the second device automatically communicating to wirelessly exchange data subsequent to pairing when the first portable biometric device and the second device are within wireless communication range;
• wherein data comprises sensor data collected and stored by the first portable biometric device.
