The most well-known fraud is phishing: scammers pretend to be a well-known company and send you an email or SMS asking for your credit card numbers. Most of the time, the fraudsters then use your credit card numbers to make purchases on the Internet for you. They use websites that do not require Luxtrust or 3D Secure authentication. This allows them to make many purchases and easily steal the money in your bank account. If you notice any fraudulent payments on your account, stop your card immediately and inform your bank advisor.
