IDFCFB credit card is not easily available to the masses. IDFC First Wow asks for FD and others need pre-approval. I don’t think there is a system to approve based on CIBIL score.
HDFC, ICICI, SBI etc in comparison have simple approvals (without FD, Savings account)
Don’t know why a mid sized bank looking to expand so aggressively doesn’t have easy procedures for issuing credit cards.
