A biometric narcotic safe opens with a fingerprint instead of a key or code. Fingerprint readers are built for slow-paced, dry environments. An ambulance is the opposite. Hands are sweaty, gloved, or have blood on them, and the medic needs the drug box open now.
That’s why we don’t recommend biometric access for EMS narcotics storage. Here’s why, and what works better.
Where fingerprint access breaks down in EMS
- Gloves. Medics wear them on almost every call. A reader that needs a bare finger means stripping a glove mid-call to reach a drug.
- Sweat and blood. A wet or contaminated fingertip is exactly the kind of read a sensor rejects. Retry once, retry twice, and the patient is waiting.
- Power. A fingerprint reader is an electronic device in the box, so it needs a power source on the vehicle. That’s one more thing to install, wire and keep charged.
- The workaround. When a lock is unreliable under pressure, crews find ways around it. A box propped open or an override code everyone knows defeats the point.
Fast, reliable access on scene isn’t a nice-to-have. A narcotics lock that fails when a patient is crashing will be worked around, and then you have neither security nor a reliable record.
What we use instead: a smart key that keeps the accountability
NarcLock gets its accountability from a smart key, the NarcKey. Each medic carries their own. It’s programmed with exactly which boxes they can open, on which days and hours, and until when.
Touch it to the lock and it opens, gloved hand or not. There’s no reader to wipe and no wiring on the vehicle or at a remote station. The NarcKey powers the electronic cylinder at the moment of contact.
Every opening is recorded in both the lock and the key: which key, which box, the date and time, and whether access was granted. The lock stores up to 6,500 events and the key holds up to 12,000.
What about someone borrowing a key?
A NarcLock key is tied to one person, and the system makes a borrowed key hard to use and easy to spot:
- Expiration. Keys can be set to stop working at the end of a shift unless they’re docked and refreshed. A borrowed key has a short life.
- Lost keys. A lost or stolen key goes on a lost key list. Locks refuse it and record the attempt.
- Two-person access. A box can be set to require more than one authorized key before it opens, up to four. That works well for a station safe or a waste process.
- PINs. Agencies can require a PIN when a medic updates their key at a communicator, which ties the key to the person at the start of each shift.
None of that needs a bare, clean, dry finger in the back of a moving ambulance.
On a rig, the key wins every time. If you want to see it on your own vehicles first, ask us about our free pilot program.
