Could you show me your license?
Literal
License [object-を] show-[humble-receive-いただけ]-can [question-か].
Polite request using 見せていただけますか — 'could I humbly receive your showing?' A slightly less lofty alternative to the 拝見できますか framing; both belong to keigo register, but 拝見 puts more weight on the speaker's humility, while 見せていただく puts more emphasis on the listener's action.
