There`s supposed to be a uniquely formed physical configuration input-output...behind that an input -output authenticator....

The uniquely formed I/O....although it has a unique physical configuration..it can still use standard protocols...such as USB2 or IEEE1394(Firewire..iLink) which can be utilized for the authentication process.

Perhaps they decided to implement the wireless configuration right from the get go.
