Even if you follow all security precautions, it's still possible for thieves to gain access to your credit card. If this happens, you should report the charges to your credit card issuer immediately to report any unauthorized purchases. Be prepared to provide them with personal information, including your legal name, address and Social Security number. From there, your card issuer will likely cancel your current card, review and remove fraudulent charges and issue you a new card. We also recommend checking any other credit accounts to make sure hackers didn't gain access to additional payment methods. You can reduce your chances of becoming a victim of credit card fraud by keeping your eye on your credit card bills, using enhanced security tools and following basic credit card privacy guidelines.
