SerCal [wireless waiter calling system]

The SWIS Server Caller (SerCal) is a paging system for restaurants and pubs. The system allows restaurant/pub patrons to electronically "call" their server to let the server know that the patron is in need of assistance or ready to order. The system would consist of a transmitter unit placed discretely on every table, and a portable transceiver unit carried by the server. When a patron presses the transmitter unit, the server would be notified on his/her transceiver unit that a particular table needs his/her attention. The transmitter unit could be decorated to display a sign or menu item. The transceiver unit carried by the server allows the server to know which tables require assistance in a simple glance.
