Nothing costs less than .1 essence. Also, aren't there already nanotats? What is the need for this older tech?
Nanotats cost no essence, they just decay. This unit is permanent, and unlike the rest of the cyberware in SR, the only invasive part of it is the connection to the blood vessels (a connection to the vein and artery). There is no nerve connections and there is no permanent bonding with the cells or bones.
