Legal analysis: Alipay and bank card are not a system. The freezing of the user's bank card will not affect Alipay. After the account is frozen, it can only be recorded and cannot be released. If it is the only bank card associated with Alipay, it cannot be used normally. Users can unbind and change the frozen bank card and rebind the bank card.

Legal basis: Article 75 of the Cyber Security Law of the People's Republic of China.
