The most advanced airport in Tokyo uses SMS (text messaging) and a barcode for ticketing.
At Haneda, passengers can order a ticket online via the internet and the airline will send a barcode by SMS to the customer.
The passenger just has to hold the phone under one of 52 scanning devices at the airport and they are checked in.
According to ANA, passengers will need just eight seconds to check-in compared to the usual two minutes for passengers who check-in at the gate.
Already 70 percent of passengers at Haneda use these electronic tickets.
