Pager Genius pagers work great in a supermarket setting. Supermarkets use pagers at meat counters, pharmacies, and bakeries. Customers place an order and then can shop around the store with the pager. When the pager alerts, the customer knows the order is ready for pick-up.
The Pager Genius System does not connect to the internet or any phone lines, so there are zero monthly fees. Paging pager #7 is as easy as pressing the seven button, followed by the call button; it is really that easy to page someone.
