BEIJING, Dec. 12 (Xinhua) — China announced on Monday that a digital tool to track cross-city travel will go out of service starting Tuesday.

The telecommunication-based digital tool — also known as the digital travel code — will end its service on all channels following the requirements of the central authorities.

The digital travel code was put into use in 2020 as part of the country's COVID-19 prevention and control measures. It has enabled the tracking of individuals' cross-city travels to help local governments take targeted steps to guard against potential contagion risks.
