Token dispensers provide an efficient way to manage queues in a variety of places such as banks, hospitals, parking lots, restaurants etc.
When a customer wants to enter a queue, he/she presses the button, and a token is automatically dispensed from ther machine. The token has a serial number, date, time, etc on printed on it. The customer retains the token till the time his token number is announced.
This system eliminates long standing queues in offices, thus spacing both space and energy.
