Fast lanes cut waits to re-enter country

It's getting easier for foreign residents to enter China at Shanghai Pudong International Airport. As of Friday, some expats will be allowed to use self-service immigration lanes that cut long waits down to just seconds.

But there are certain conditions.

Only foreigners with valid residence permits of more than six months are eligible. And they must be holders of e-passports, biometric passports that store on electronic chips data concerning their facial features and fingerprints.
