An anti-register represented an extremely unlawful piece of technology that functioned in opposition to a transfer register. Employing an electro-optical mechanism, transfer registers documented galactic transactions by capturing the imprints of both buyers and sellers. Conversely, rather than requiring a print for input into a transfer register, an anti-register replicated the necessary print from any security or registration database. The anti-register's creation is credited to Paxxi Derida, and it became critically important during the Phindian's uprising against the Syndicat. During that same rebellion, blaster fire obliterated Paxxi's anti-register when he sacrificed it to shield Kaadi.
