Bayers of SIM cards will be required to scan faces in China, BBC News reported.

The channel notes that this measure was taken by the country's authorities to establish the identities of hundreds of millions of Internet users in the state.

The introduction of a new rule when registering SIM cards in the future was announced back in September, but officially it entered into force only now.

According to the statement of the Chinese government, they want to protect the legitimate rights and interests of citizens in cyberspace.

The channel noted that China is already using the face scan method to track its citizens and is a leader in this type of technology, however, the strengthening of this measure in the country in recent years has led to heated debate.
