Black Meridian Biometric Deadbolt

The deadbolt reads approved living tissue, checks pulse and temperature, then drives a hardened bolt into the berth frame. Clean the reader with alcohol, not abrasive galley powder; greasy prints make it smell like old coins and reject legitimate hands. The lock suits cabins, clinics, and sensitive lockers where shared codes have become a joke. It delays casual entry and records attempts. Gloves, burns, cold skin, cloned samples, and severed network trust all complicate matters. Always retain a controlled mechanical route, unless suffocating behind a very clever door is part of the security plan. Black Meridian ships in a solvent-resistant case with tamper-evident fasteners and a log strip that cannot be wiped remotely. Corporate security buys it by requisition number; working crews usually acquire one after a very specific bad night.
