There may be many reasons why Alibaba cannot use family card payment. First, family card is a special payment method, which is usually used for mutual transfer and payment between family members. This payment method involves trust and security issues between family members, so Alibaba needs to ensure the stability and security of this payment method. Secondly, Alibaba is a global e-commerce company, and its payment system needs to take into account the laws, regulations and regulatory requirements of different countries and regions. In some countries and regions, family card payment may not be allowed or restricted, so Alibaba needs to formulate corresponding payment strategies based on the laws, regulations and regulatory requirements of different countries and regions. In addition, Alibaba's payment system also needs to take into account the user's payment experience and convenience. If Alibaba introduces the family card payment method, it needs to take into account the user's usage habits and payment needs, and it also needs to invest a lot of manpower and material resources to develop and maintain this payment method. In this process, Alibaba needs to consider user feedback and opinions to ensure that this payment method can meet user needs and expectations. Finally, Alibaba is a commercial company, and its main goal is to provide high-quality e-commerce services and make profits. Therefore, when introducing a new payment method, Alibaba needs to consider the cost and benefit of this payment method. If the cost of introducing the family card payment method is too high or the benefits are not high, then Alibaba may choose not to introduce this payment method. In short, Alibaba cannot use family card payment due to many reasons such as technology, law, user experience, and commercial interests. If users need to use family card payment, it is recommended to consult Alibaba's customer service or relevant departments to learn more about the information and requirements of family card payment.
