As workers do their job, GRAVITY does its magic ensuring cards/keys are always kept close at hand.


Press on the key unit’s thumb release button and return it to the belt unit with a simple click and snap.

Three Way Separation Alarm:

When keys separate, the alert is instant and fool-proof. Belt and key units emit unique alarms based on feel (vibration of belt unit), audio (chirp and louder 85 dB alarm on key unit), and visual (strobe on key unit).

Industrial-Grade Quality:

GRAVITY is designed for industrial environments with usability in mind. The vibration feature can be felt through heavy utility belts and the 85 dB audio alarm can be heard in loud environments. GRAVITY runs on standard AAA batteries with an average life of six months. Once batteries reach 20% capacity, a warning chirp alerts users that they need to be replaced.


Multiple GRAVITY units can work in close proximity to one another because each key unit is uniquely married to its belt unit via an RF signal generator.


The key unit can be placed in a low-power state for off-shift storage within an access control cabinet. Removal from storage without re-holster to a belt unit causes alarm.


Prevent one key loss event from happening and the GRAVITY has paid for itself.
