SMS verification code is an effective verification code system by sending verification codes to mobile phones. Both large websites, especially shopping websites, have the verification code function of SMS, which can ensure the safety of shopping more accurately and safely and verify the correctness of users. Some authentication code providers provide SMS authentication code service. Each website sends a request to the provider's server through the interface, and the server sends random numbers or letters to the mobile phone, and the provider's server verifies the authentication code uniformly. Before entering the mobile phone number of the registered member in the system, remind the registered member that the entered mobile phone number must belong to the registered member himself, and the mobile phone is beside the registered member at the moment. If you don't have your mobile phone, you need to ask registered members to bring their mobile phones to re-apply. The registered member's mobile phone will receive a random short message with verification code, which mostly reads: "Dear customer, the verification code of a service provided by a certain company is * * * * * * To ensure your privacy, it will be used within half an hour." Members use this verification code to register or verify their identity. If the registered member does not receive the verification message or verification verification code within half an hour, the verification code is invalid. Click the "Send Verification Code" button again, and the system will send the second verification code to the registered member's mobile phone. You need to re-enter the second verification code in the "Verification Code" column.
