The guy ate a barbecue for 550 thousand and was brushed away. How to prevent stealing brush?

At present, most stolen bank cards are magnetic stripe cards. Because the technology of magnetic stripe card is no longer a secret, it has been applied in many fields, such as access cards. Cloning a magnetic stripe card is very simple, and the security is naturally relatively poor. It is a good choice to use chip card instead of magnetic stripe card. So far, there has been no theft of the chip card.

The information of the chip card is dynamic, and the chip is a small computer, and the check value is different every time, so the possibility of copying is small.

2. Don't leave bank card information when spending.

When shopping on websites and mobile phones, try not to keep bank card information. For example, some websites have exposed users' CVV codes before. This set of codes is to prove that the cardholder is stuck in the cardholder's hand when the cardholder and the merchant are not face to face, because only the cardholder can see this set of codes. But if the website stores this information, once it is leaked, it may be stolen.

Don't give your mobile wallet to others.

Consumers should be careful not to give their mobile phone wallet carriers (such as SIM cards, SD cards, mobile phones, etc.). ) for others to use. Consumers should pay attention to properly keep personal identity information, bank card information, all kinds of financial service passwords, verification codes and electronic tokens.

Download financial service application software through formal and secure channels, and carefully connect unknown network hotspots or click website links. Regularly modify all kinds of passwords in financial business, improve the complexity of passwords and strengthen the security of passwords.
