priority number queuing system
So, I think there are more than one service counters in this case. What about queue ticket dispensing? Is it going to be a single queue ticket printer? If yes, you may consider using a PC controlling the Q number and doing the ticket printing management. That PC is connected to keypads via some sort of RS485 network, or LAN network. Say, you have 10 counters with 10 keypads. Each keypad is showing the current customers in the Q. The service provider at each counter could make a free-hand keypress for a 3-digit Q number (say 123). To avoid mistake, each keypad is equipped with a LCD display to show the current number on call. An ENTER key to confirm calling, and then that Q number would be deducted from the control controlling software....
