According to crowdsourcing, crowdsourcing platform does not support binding other people's bank cards. Binding bank cards requires real-name authentication and risk assessment, and the platform needs to ensure account security and transparent capital flow, and avoid problems such as misappropriation of funds. Therefore, when using crowdsourcing platform for fund settlement, I generally need to use my bank card for binding and management.

Bank card refers to a credit payment tool issued by commercial banks (including postal financial institutions) with all or part of the functions of consumer credit, transfer settlement, cash deposit and withdrawal, etc. Bank card reduces the circulation of cash and checks, which makes the banking business break through the limitation of time and space and undergo fundamental changes. The application of bank card automatic settlement system makes the dream of "no cheque, no cash society" come true.
