New measures requiring operators to carry out facial recognition scans of customers as part of the user identification and verification process came in to effect on Sunday, Reuters reports. The rules, published by sector watchdog the Ministry of Industry and Information Technology (MIIT) in September this year, oblige operators to perform the check on new customers or subscribers signing up for a new service. The new measures are an extension of the country’s existing real name registration rules, which are intended to limit fraud and prevent the use of mobile phones in criminal activities. Alongside the facial recognition scan, providers were instructed to make it clear to customers that they must not resell SIM cards to third parties. Finally, operators must also allow customers to check which mobile numbers have been assigned to them, to ensure that others have not wrongfully registered a phone line in their name.
