The difference between the purchase with a debit card and the purchase with a credit card lies in the way of financing the amount to be paid. Thus, in the purchase with a debit card, the money with which the purchased good or service is paid is immediately withdrawn from the bank account of the cardholder, with which the debit card works as a cash payment but without use paper money. On the other hand, when paying with a credit card, said amount is not subtracted from the account, but instead a debt is taken with the bank, which must be paid after a certain period.
