Methodology
 Number of visitors to that place
 Work culture of visitors
 Work profile of the visitor
 Type of area
 Nearby population
 Turnover of the restaurant

Applications
 Hotels
 Restaurants
 Cinema Halls
 Parking

 One time investment when looked upon economic terms.
 The cost of workforce or the people hired for serving are absent
thereby cutting cost.
 This method is time saving because neither the customer has to stand
in queues nor he has to wait for the waiter to come and take the order.
 It is reliable as machines don’t make frequent errors.
 Ease in placing multiple orders – quite comfortable.
 It is better for both old-aged people and pregnant women with low
level of exertion.
 Menu can be easily updated.
