Debit card is a kind of payment tool directly related to bank account, and the repayment method is different from credit card. Debit card repayment mainly depends on the user's bank account. When repayment is required, the bank will automatically deduct the corresponding amount from the user's account without manual operation by the user. The way of automatic deduction makes the repayment process of debit card relatively simple and convenient. Users can also make manual repayment through online banking, mobile banking and other channels.
