If you apply for CMB credit card through online channels (except door-to-door application and professional application), you need to bring the original ID card to the CMB counter (both in the same city and in different places) for face-to-face signing after the preliminary examination. If the system passes the preliminary examination, it will trigger a face-to-face SMS invitation, which is valid for 30 days. Whether the interview can pass or not depends on the final result.
