Bluetooth Button Applications

Smart Healthcare

In the healthcare industry, the H3 Button can be used to enhance patient safety by enabling instant SOS alerts in case of emergencies. Healthcare staff can wear the H3 Button to access restricted areas and track attendance, ensuring that only authorized individuals have access to sensitive areas. Its motion detection and panic button capabilities can help prevent accidents and ensure staff safety.


The H3 Button can be used to monitor workers’ safety and improve communication between workers and management. Onsite workers can wear badges to report any unsafe working conditions, request help in an emergency, and track their attendance. This can help improve workplace safety by ensuring that workers are aware of any potential hazards and can easily report any incidents that occur.

In smart offices, the H3 Button is versatile for access control, attendance tracking, and visitor analytics. It plays a great role in ensuring staff safety and providing emergency assistance if needed. The H3 Button’s Geo-fence alerts and restricted entrance alerts can also be useful for managing visitor access and enhancing workplace security measures.

Warehouses & Factories

The adoption of H3 Buttons in large warehouses and factories can significantly enhance worker safety by enabling access control and tracking attendance. It helps track worker movements and ensure that they are not entering restricted areas. Moreover, the H3 Button can be affixed to assets using 3M stickers to facilitate efficient tracking of assets.
