Eyewear charging case using charge pins as communication path

A method for use with an eyewear device and a case for the eyewear device, the eyewear device comprising a temple with a conductive interface, the case comprising a housing having an interior wall, a contact positioned on an interior back wall of the housing to couple with the conductive interface of the temple, and circuitry including a processor coupled to the contact, the method comprising:

• detecting connection of the conductive interface of the temple of the eyewear device with the contact supported by the interior back wall of the case;
• and
• in response to detecting connection of the conductive interface of the temple of the eyewear device with the contact supported by the interior back wall of the case at least one of providing an electrical charge at the contact of the case to the conductive interface of the temple of the eyewear device or exchanging data with the eyewear device via the contact and the conductive interface.
