For travelers, using airport kiosk has several benefits. First, there is the time it saves, especially in China where people are already aware of fact that hours spent queuing at airports to check in won't come back as useful consciousness later on. Because tickets can be booked so easily online nowdays, passengers just present their booking number or passport at the self-registration machine then swipe a card to confirm their payment and receive both boarding cards with tickets by mail at home before departure. Second, an kiosk makes people self-sufficient, parents who owe their children everything because they are still young at heart. The independence this gives is especially valuable in the peak periods of holiday travel when the airport's staff can find it difficult to cope. Third, human error will be greatly reduced when smart machines complete these tasks. In addition, tracking to evolving details of your scheduled flight can provide information that is useful in making adjustments and decisions for the meantime. Finally, the kiosk reduces stress and makes airports more pleasant overall places to come and go than they were in the past with long lines for anything just gone, ticket counters that only open on weekdays or take twenty minutes each customer at rush hour times, please.
