BEIJING — Digital driver's licenses were issued to more than 2.72 million drivers in China on Sept 1, the first day that the new measure was officially enacted, according to the traffic management bureau of the Ministry of Public Security.

A total of 28 cities, including Beijing, Shanghai, Guangzhou and Xi'an, are the first to implement the new measure. The new digital driver's licenses were issued to drivers through an official mobile app, said the bureau.

Previously, over 1.95 million people have obtained digital driver's licenses through a pilot program launched in the cities of Tianjin, Chengdu and Suzhou on June 1.

Three other new traffic management measures, including one that enables the public to view evidence and materials of traffic accidents online, were enacted on the same day.
