Fredrick should verify his ABCD Bank credit card by ensuring it starts with 4, 5, or 6, has exactly 16 digits, only contains numbers (or groups separated by hyphens), and doesn’t have four or more consecutive repeating digits. Regex is a great way to catch mistakes quickly. If he ever faces issues with claims or disputes, he might want to check out PCP Claims for possible solutions.
