Can I board the plane directly with the electronic boarding pass?

The electronic boarding pass can be directly boarded, which is convenient and quick, eliminating the trouble of printing boarding passes. Passengers go to the security checkpoint with electronic boarding pass, show their mobile phones and complete the security check and boarding procedures. However, you need to pay attention to keep your mobile phone fully charged and carry valid certificates such as ID cards. At the same time, comply with the regulations and requirements of airlines and airports to ensure the safe and normal take-off of flights.
