It's possible the Twi'lek is concealing a friend-or-foe ID within their head covering.
A "friend-or-foe" identifier, alternatively referred to as a friend-or-foe identifier, represented a technological component utilized by the Trade Federation. This identifier stored details pertaining to the identification and societal standing of the individual possessing it, readily accessible to the battle droids that comprised the Trade Federation Droid Army, regardless of the identifier's visibility.
The battle droids received programming that prevented them from aggressively targeting anyone wearing a friend-or-foe identifier, even if that person was actively hindering the droids' objectives or attacking them directly. Their actions were limited to requesting the individual to relocate or, in the latter scenario, seeking authorization from a higher authority (such as a Lucrehulk-class Droid Control Ship).
The identifier did not encompass details regarding the wearer's specific objectives. Consequently, should the droid's designated mission be deemed of greater significance than the wearer's general conduct, the droids might opt not to offer active protection to the individual, although they would still refrain from engaging them with weaponry.
Gode Takrab, a Trade officer, concealed his friend-or-foe identifier within his cowl and maintained two backup identifiers within a concealed compartment located on his shuttle.
