Self-services such as checking personal information at railway station's turnstiles and checking in and checking out of the station will also be available to these holders, according to the company's release.

Also, international travelers holding ordinary passports can check their personal information online at the platform of 12306, by filling-in their information including names, nationalities and passport ID, from Tuesday. They can also upload pictures of their passport information to the platform for checkup.
