the same registrant's credit card and physical bank account are required to bind the store.

in mercari, a coal stove, the identity authentication will be skipped when the bank card of a virtual account is bound. Generally, when a store encounters such authentication, it is almost impossible to pass, and it can only "give up treatment" for the funds to be withdrawn in the store. After testing, if the store is bound to the store through the credit card and physical bank account of the same registrant, it is extremely safe.
