Steel plates and paper records: keeping both aligned

Steel recovery plates solve a different problem than bound ledgers. The plate holds the seed or split fragments; the ledger explains which plate belongs to which wallet, where the plate is stored, and what verification date you last confirmed its presence.

We suggest a three-column backup map in your record book: wallet label, backup type (steel / paper / device), and location code. Location codes should match physical labels on boxes or safe drawers—“BUS-2F-SAFE-A” rather than “the safe upstairs.”

When you engrave a new plate, add a ledger row before you store the plate. Clients who engrave first and document later often forget which wallet a plate was meant for when multiple migrations occur in the same year.

Humidity matters for paper stored near coastal apartments in Busan. Keep steel plates in their intended containers; keep the ledger in an archival slipcase inside a climate-stable room. The ledger should note environmental concerns if a backup site is a garage or boat locker.

During verification, touch the plate location and update the log date—even if you do not open the plate. Alignment between physical reality and paper record is the disaster recovery outcome we optimize for.
