3DS service paging system is ideal for fast food restaurants or cafes. After the customer orders at a fast food restaurant or cafe, the waiter only needs to hand the pager to the customer, and the customer is free to walk around the restaurant or sit at the table and wait for food. When the food is ready, the pager lights up and vibrates to notify the diners to take food. The customer can return the pager to the waiter when they pick up the food. The process is easy and enjoyable, which helps to increase the customer’s goodwill and loyalty to the restaurant.
