Meet Secufy: a smart SOS button that lets you quickly get in touch with your loved ones. It allows you to alert up to 3 contacts when you press 3 times. Each person gets your text message with GPS coordinates. They also see who else was notified.
This button is compact and IP67 dust & waterproof. It can be worn around your wrist or neck. Secufy is compact enough for you to easily carry on your keychain. No need to use a smartphone to connect this device either.
