MK-12 scanner

A MK-12 scanner

An MK-12 scanner was a Cardassian security device used to verify identity, a more advanced scanner than the MK-7 scanner.

In 2369, the assay office on Deep Space 9 used an MK-12 scanner with an L-90 enhanced resolution filter as a lock on its storage cubicles.

The combination of the scanner with the filter allowed for an incredibly detailed and accurate retinal scan. The level of security was deemed just satisfactory for Vash when she visited the station upon her return from the Gamma Quadrant. (DS9: "Q-Less")
