DNA slot

The DNA slot is a means of identification for Covenant Sangheili. The DNA slot consists of a rectangular black box standing about five units high. Green light sprays out of a slot on the structure's side where the Elite is supposed to place their hand. When this is done, the machine samples their tissue and compares its DNA with that on file.

These are seldom used except in formal meetings with Prophets or other members of the High Council as to prevent any assassination attempts. When they are used, they are often guarded by a squad of Special Operations Elites who also must be presented with an Identity Disk before they are granted passage.
