Yes. Because your credit card information is leaked, someone will make rude phone calls to you, defraud you, threaten the safety of your family, and steal your money. A credit card, also called a credit card, is a credit certificate issued by a commercial bank or credit card company to consumers with qualified credit. It takes the form of a card with the issuing bank's name, validity period, number, cardholder's name and other contents printed on the front, and a magnetic stripe and signature strip on the back.
