After the user's loan is successful, all the money from Shantou Lirong Guarantee Company will be transferred to the applicant's bank card, so you must provide your own bank card number.
If the loan product can only be used for consumption and cannot be withdrawn, then the user can apply for such a loan without a bank card. For example, if he borrows money from a bank, he can directly transfer the money to Alipay account without a bank card.
