Veinprint lock

A veinprint lock is a type of security system used by the Covenant, analogous to a biometric scanner. It verifies the user's identity by conducting a focused examination of their veins within their wrist. Because they also assess the movement of their blood, they will only unlock for a living individual; massaging a severed hand to stimulate blood flow will not fool it.

Most starships and warehouses owned by the Clan 'Umtalla on High Charity were protected by veinprint locks. During the Fall of High Charity, Jiralhanae forces were unable to co-opt the weapons and riches until they forced the scion P'thon 'Umtalla to unlock them.
