Here it works: your member will order at the restaurant front counter. The employee will grab a random pager, look at its digital number, and type that pager number into the POS system. Want to page pager #5? Press the #5 button followed by the enter button; it's that easy to operate a Pager Genius System.
Using a paging system in and around your pool is superior to food runners or overhead speakers calling out names all day. Using a paging system will keep your environment peaceful for your members but will also give you the efficiency you are looking for.
