CCB is a pure chip card, that is, it has no magnetic stripe. Although most cards are composite cards with chips and magnetic stripes at present, the financial ic cards issued by CCB are basically pure chip cards, including financial IC debit cards, financial IC quasi-credit cards and financial IC wealth management cards. For example, a credit card has a magnetic stripe chip composite card, but the magnetic stripe transaction of the composite card has been closed, and only the chip can be selected for transaction.
