1~20 keyboard only for fast pressing number
In some place, the store or shop provide self-service. Each customer gets a number and find a place to wait. When it is his turn, the server will call his number, but don't know where he is. Maybe the customer cannot hear the call while he is doing something else. Is there anything can help them?
Of course, they can use the queue wireless calling system.
Such calling system is opposite to normal. The server press the transmitter button, but each customer gets a receiver (of couse, mini one). Then no need long queue.
This one is 20 channels version, the keypad is from 1 to 20, press one of them, it sends the wireless signal directly.
