Internet cafes need mobile phone number verification code to surf the Internet.

Internet cafes need mobile phone verification codes to prevent citizens' ID cards from being fraudulently used and members' funds from being stolen. Internet cafes require users to provide their mobile phone number when surfing the Internet for the first time, and verify it through the verification code received by the mobile phone. The user only needs to swipe the ID card, and the mobile phone will automatically obtain the authentication password without providing the mobile phone number again.
