The WRC-800 is among the best and most useful calling systems for finding out about and attending to customers’ requests. When the customer presses the pager button and determines the order type, the wristband begins vibrating and the order information is displayed on it. Using this product, you can call waiters in restaurants, dining-rooms and cafes based on order type. Other applications include summoning nurses in hospital, calling the security staff in stores and malls and summoning a specific employee such as a security guard or a secretary. It can also be used in clinics, nursing homes, water parks, swimming pools, offices, factories, hotels and any other place that requires a calling system. This product is 100% waterproof and can be used in humid environments. Compared to its counterparts, the WRC-800 wristband covers more area since it is long-range.
