The Smart Ping is a necklace designed for the elderly. By using the latest Bluetooth 5.0 technology, it provides higher transmitting speed and wider coverage. Smart Ping built-in 3-axis acceleration sensor can record more activity data, including walking, running, sleeping, accidental falling, etc. With the associated app, it allows the family to pay attention to the user’s status. When it detects a fall, the smartphone calls out and sends SOS messages to the contact person immediately. With a bright and mellow appearance, it looks like the Chinese jewelry „Lucky Jade“. This means wearing Smart Ping will bring safety and well-being. The front cover is embedded into the back cover, contributing to a seamless appearance. The distress button and light are designed on the back side, not only pressing the button is more intuitive but also seeing the SOS message sent out successfully.
