For CMB credit cards applied through online channels (except door-to-door application and professional application), I 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. The time limit for face-to-face interviews is generally 30 days (subject to SMS prompts). Failing to apply for a face-to-face interview within the time limit is regarded as an automatic waiver of the credit card application, and the credit card application cannot be submitted again through online channels within 90 days.
