The Chinese government presents the move as a user-friendly way to verify identity, but critics see it as another way to monitor people in a country famous for its authoritarian governments.
China's Ministry of Industry and Information Technology (MIIT) announced the rule in September, requiring enforcement of the new measure on December 1.
This follows a trend in China as the government are already using facial recognition software to survey those living within its borders.
If you need to pick up a new SIM card in China, you're now required to have your face scanned to verify your identity. It is a world leader in such technologies, but more and more use of these across the country has sparked a debate.
China has for years been trying to enforce rules to ensure that everyone uses the internet to do so under their "real-name" identity.
Commenting under an article about the new rules, one user wrote: 'This is a bit too much'.
When the regulation was announced in September, the Chinese media did not make a big deal out of it.
The new legislation is part of China's wider efforts to keep close tabs on its citizens and monitor their activities and behaviours. Of course, citizens in the country are used to a controlling government.
China's facial recognition measures increasingly extend not only to shops and public spaces but also homes and now mobile phones.. It is used more and more, for example, to pay in shops and supermarkets.
Simply final month, a regulation professor in China's Zhejiang province filed a civil lawsuit towards a wildlife park for forcing him to offer his with the intention to be admitted to the park, which he considered as a violation of his client rights.
Researchers have previously warned of the privacy risks associated with gathering facial recognition data but consumers have widely embraced the technology.
