Summary
Bank of America’s fraud system aggressively scans for unusual behavior, especially big “day-one” charges and rapid repeats. Clients who immediately spend close to their limit are more likely to face declines or account reviews. BOA prefers measured spending increases over several days rather than one large purchase. Spacing out charges and keeping spending moderate helps ensure smoother approvals.
