1. An adapter device for use in communicating with a first electronic device and a second electronic device, the adapter device comprising:
an adapter memory component;
a first connector operative to maintain a first communications link with the first electronic device;
a second connector operative to maintain a second communications link with the second electronic device; and
an adapter host subsystem communicatively coupled to each one of the adapter memory component, the first connector, and the second connector, wherein:
the adapter host subsystem is operative to switch between enabling a first communications path between the adapter memory component and the first communications link via the first connector and enabling a second communications path between the adapter memory component and the second communications link via the second connector;
each of the first and second communication links comprises one of a contactless communication link, a wireless communications link, and a mechanical communications link;
the first communications link is operative to communicate data between the first connector and the first electronic device according to a first communications protocol;
the second communications link is operative to communicate data between the second connector and the second electronic device according to a second communications protocol;
the adapter host subsystem comprises a controller;
the first communications path comprises at least a first portion of the controller between the adapter memory component and the first communications link;
the second communications path comprises at least a second portion of the controller between the adapter memory component and the second communications link;
when the first communications path is enabled, data is communicated along the first communications path according to the first communications protocol; and
when the second communications path is enabled, data is communicated along the second communications path according to the second communications protocol.
