JD.COM express payment does not need to pay a password?

JD。 COM express payment needs to be associated with a bank card: in the use of express payment, in order to reduce the number of times that cardholders enter the bank card number and password and reduce the risk of sensitive information leakage, UnionPay provides the association function of "account | bank card", which can be paid without entering the card number and password, but only by using the mobile phone verification code.

Therefore, fast payment directly deducts money from the bound bank card, and there is no need to enter the transaction password again.
