Want to improve credit card security? You need to see these tricks.

Now more and more people choose to apply for credit cards from major banks, not only because they can enjoy the convenience of spending in advance, but also because banks will design various preferential activities to attract consumers. However, after successfully applying for a credit card, the security of the credit card cannot be ignored. Many criminals will use some loopholes to steal our personal information and cause our economic losses. Below I will sort out the common means of credit card fraud and our preventive measures for everyone. Let's have a look!

How do others cheat?

1. Send a link message through an acquaintance. When we see short messages from relatives and friends, our first reaction is of course to believe them, but we don't know that this short message probably carries Trojan virus, which leads to the theft of the balance and limit of bank cards.

2. The ghost of the bank. Don't trust the bank staff completely, give them the credit card. There have been cases where others have been cheated, so everyone must conduct credit card transactions face to face and don't tell others the password.

3. Refund and change SMS. If you receive some refund or change SMS, you need to provide credit card number, expiration date, verification code and other information, which is likely to be fraudulent SMS. Everyone must remember to check with the official before dealing with it accordingly.

How do I break it?

1, call back. In view of the fact that many swindlers pretend to be bank staff, one way to find out is to call back the bank customer service to verify the authenticity after asking the other party's work number.

2. query. One way to deal with SMS and web fraud is that we take the initiative to search the links of relevant websites to find out whether the query is the real official website.

How else can we prevent it?

1. Ask the platform to delete the leaked information. According to the National People's Congress Standing Committee (NPCSC)'s "Decision on Strengthening the Protection of Network Information", when we find that personal information has been made public, we have the right to contact relevant platforms and ask them to withdraw it.

2. Defend rights through complaints. If you find that your information has been leaked, you can also complain to the public security department, the industrial and commercial department and other relevant institutions to safeguard your rights and interests according to law.

In short, knowing ourselves and ourselves can better safeguard our rights and interests. We need to know in advance what means criminals will use to cheat, and what we can do to prevent being cheated, and how to protect our rights and interests after being cheated, so that our rights and interests can be protected to the greatest extent.
