The system is perfect for restaurants and nursing homes. Messages are sent from a base transmitter to a watch receiver that the server or caregiver wears for easy access.

The base transmitter consists of four large, color-coded buttons. Establishments can either order and attach stickers that have the words they wish each button to represent or include a card with each unit that has explanations. For a restaurant, the buttons could correspond to simple commands, like “Ready to Order”, “Refills”, “Issue with Order”, and “Check Please”. But the buttons have no assigned meanings until an establishment gives them one, making the system fully customizable and adaptable to a wide range of businesses.

When pressed, the buttons light up to show customers that their signal is being sent. A corresponding colored light on the back of the unit also illuminates to give servers a bright visual signal. The signal is also wirelessly sent to the servers watch, which vibrates and lights up with the color of the button pressed. A number overlay indicates which unit sent the signal.

This system allows multiple transmitters to send signals to one or more receivers without alerting servers who aren’t handling that table. The server can touch the color notification to acknowledge it, which turns the lights off on the transmitter. This is a visual signal to the customer that their signal was received.
When servers are assigned to a table, they insert a wireless USB dongle in the back of the transmitter which is linked to their watch. The system is completely wireless, and includes an internal lithium-ion battery that can be recharged after the days use.
