The Proxidyne Wireless Grocer Cashier Call Button System allows cashiers to easily request help so that they can keep working. To request assistance, they just touch one of several labeled buttons which announces a specific request such as “change needed” or “price check” on the staff's 2way radio or smart phones. Proxidyne creates and operates an IoT platform for wireless button and sensor management, monitoring, and analytics for its sensors, buttons, beacons and mobile apps. The company serves customers in the grocery industry through its authorized resellers. (less)
