The credit card of China Merchants Bank and debit cards of other banks have opened the automatic repayment function. At present, only Minsheng Bank in Chongqing is involved. Cardholders can fill in the paper agreement form through Chongqing regional bank, apply for the binding connection between other bank accounts and our credit card, and open the inter-bank automatic repayment service function. After verification by participating banks and credit cards, the credit card center initiates automatic repayment transactions on the last repayment day of each month (except corporate debt business cards).
