When people evaluate emergency devices, one question comes up often:
- Why doesn’t it have GPS?
- Why not cellular?
- Why not add more features?
On the surface, more capability sounds better. But in practice, every feature comes with a trade-off, especially when it comes to battery life, reliability, and day-to-day usability.
The trade-off most people don’t see
Devices with GPS, cellular radios, or always-on communication require significantly more power.
That typically means:
- Frequent charging
- Larger, more complex devices
- Greater risk of failure at the moment they’re needed
For a device that needs to be worn by every staff member, every day, those trade-offs matter.
If it needs to be charged constantly, it won’t be consistently ready.
Designed for consistency
The Rescue Card is built around a different principle:
It should work reliably, with minimal maintenance, for everyone.
That’s why it uses:
- BLE (Bluetooth Low Energy) for continuous location awareness
- LoRa for long-range, reliable emergency communication
- A replaceable battery that lasts approximately one year
No need for daily charging or constant attention. It’s a device that’s ready when it’s needed.
A system, not a standalone gadget
For out-of-building scenarios, the Rescue Card can connect to a mobile device, extending functionality without requiring the card itself to carry high-power components.
This allows the system to remain low-maintenance while still supporting broader use cases when needed.
The direction this is going
Over time, wearable devices are becoming more universal.
The same card can support:
- Identification
- Access control
- Emergency response
But for that to work at scale, the device has to meet a simple requirement:
It has to be low maintenance, long-lasting, and dependable.
That means making intentional trade-offs, not adding every possible feature, but selecting the ones that ensure the system works consistently across an entire organization.
