Does credit card fraud require a password? This is not necessarily true. After all, many credit cards are stolen because the card is with you, so whether or not you set a password is of little use to the fraud. However, if the credit card is lost and the password is not used for fraud, it can be mainly divided into two situations: 1. Foreign website consumption does not require a password: It is said that on foreign websites, as long as they have your credit card information, including the credit card Card numbers, expiration dates, and security codes can be used to make purchases and transfers without entering a password. Therefore, if your credit card has a password but important information is leaked, it can easily be stolen. 2. You can swipe a QuickPass credit card without a password: Previously, someone did an experiment. Holding a credit card with QuickPass function at a POS machine with the QuickPass logo, you can still swipe the card without entering a password. In this case Setting a password on your credit card is useless. This principle is that the credit card with Quick Pass function automatically activates the small-amount password-free and visa-free function. As long as the amount of the card is less than 1,000 yuan, you can make consumption through the password-free and visa-free function without entering a password. All in all, credit card fraud does not necessarily require a password. Of course, this does not mean that credit cards do not need to have a password. Anyway, credit cards can be fraudulently used with or without a password. If you are in China, setting a password is still more important. Of course, the only way to prevent your credit card from being stolen is to protect the important information of your credit card. In this way, as long as the credit card information is not leaked, there is no way for anyone who wants to steal your credit card.
