The two-dimensional bar code of electronic boarding pass is combined with encryption technology to ensure the security of information. The two-dimensional code for mobile phone boarding, just like the snowflake pattern when there is no image on the TV screen, contains the specific information of passengers and flights, including passenger name, flight number, boarding gate and seat number, which is much more difficult to copy than the traditional one-dimensional bar code; Passengers still need to provide ID cards with photos when they pass the security check. Security personnel can use this to check whether the message is a kiss.
On April 8, 2009, China Southern Airlines cooperated with China Mobile to launch electronic boarding pass service in China. Passengers can board the plane directly through the security check only by holding their ID cards, or by SMS and QR code sent by airlines. Passengers can apply for their own electronic boarding pass in the online electronic boarding pass service system 14 from the day before the flight takes off to 30 minutes before the flight takes off.
People can also use their mobile phones to write short messages to "apply for boarding passes" and follow the prompts to apply for electronic boarding passes with short messages and MMS QR codes. After that, China Southern will send a short message containing the passenger's name, flight date, flight number, seat number, QR code picture and other information to the passenger's mobile phone.
After arriving at the airport, passengers who have not handed in their luggage can directly check in and board the plane with the second-generation resident ID card; Passengers with other valid and legal identity documents can board the plane with the short message QR code boarding pass. People can apply for electronic boarding pass in advance without going to the airport, which saves the time of queuing at the airport to check in, and at the same time, they can choose their seats online in advance without printing the traditional paper boarding pass.
