After I applied for a treasure card in Tmall channel, why did I receive a text message confirming the order number, prompting me to complete my real name registration before delivery?

To apply for Unicom Alipay card, from now on, at the request of the real-name registration system, the Ministry of Industry and Information Technology and other competent departments, new telephone users will receive real-name authentication SMS before delivery, and they must upload photos of the front and back of the user ID card and take a selfie. You need to prepare relevant certificates. We will strictly guarantee the security of the information you provide and review and deliver it for you as soon as possible. Thank you for your understanding and cooperation.
