The Access Keeper — Tap-to-Unlock with a Searchable Audit Log
You'll walk away with: A tap-to-unlock access panel on your desk that Claude Code built — a 13.56 MHz reader that recognises tags you've enrolled by name, logs every tap (known or unknown) to a searchable local database, alerts you on an unregistered card, and optionally fires a relay — with an enrollment CLI, an audit log, and a local dashboard you can open on your phone.
