Life tips to prevent fraud:

First, many people who are cheated in life are old friends, so we should instill some basic anti-fraud knowledge with the elderly at home at ordinary times to prevent their kindness from being used by some bad elements. We should communicate with the elderly more.

Secondly, if there are old people in our family, we need to help them keep their wealth. You can ask your parents to give you their bankbooks and bank cards, so that you can keep them properly and prevent the elderly from being cheated. This is a very effective method. Everyone can communicate with the elderly.

Third, many people in our life will receive strange phone calls, most of which are deceptive. In fact, it is very simple for us to identify these phone frauds, that is, we don't do anything to pay money, so those deceptive calls will not succeed.

Fourth, the bank card at home should be kept as well as possible, especially the card number of the bank card should not be exposed to strangers casually, because now the card number of the bank card will also be used by people, especially the large bank card, which is often targeted by the bad guys. Everyone must pay attention to safety.

Fifth, the bank card password at home should be changed frequently. Many people are careless. Their bank card passwords are all their birthdays or ID numbers, so the passwords are actually very unsafe and are often cracked by bad people. Therefore, everyone should always change the bank card password.

Sixth, when we buy things online, we must pay attention to our own transaction safety and don't see some attractive website advertisements. These websites are probably phishing websites, which will quickly defraud your funds or destroy your computer with Trojans and viruses.

Seventh, don't casually tell others about your mobile phone, home phone and some contact information on the Internet in daily life, which is likely to be targeted by bad people. At present, the disclosure of personal information on the internet is very serious, and everyone must take a warning.
