Specific as shown in the figure below:
IC card is a bank card with chip as the medium. Compared with the magnetic stripe card, the chip card has higher security, and the sensitive data in the card is difficult to be copied. Moreover, the chip card not only has all the financial functions of the ordinary magnetic stripe bank card, but also has an electronic cash account, which supports off-line micro-payment, and can realize fast payment and smart card mobile payment with contactless interface.
Extended data
Chip card is the safest bank card at present. So far, there have been no cases of fraud caused by copying chip bank cards in the world. Even if part of the information of the card is read, it is impossible to copy the chip card with only limited information, and the cardholder's financial security is effectively guaranteed.
Although the mobile phone can read the bank card information, it can't transfer money. After reading the information, it will show that you can "open fast payment", but because the fast payment only supports real-name accounts and the same person's bank card, users don't have to worry about the bank card being bound by someone else's account.
As for online payment without a card, in addition to the information related to the chip card, the cardholder is also required to provide a number of information such as the payment password, the last three digits on the back of the card, and the SMS verification code. It is impossible to complete online transactions only by reading information, so the security risk has not increased, and the possibility of information being used maliciously is low.
From the perspective of security, it is recommended that cardholders use chip cards. The magnetic stripe card is limited by technology, and the information in the card is easy to be copied. The transaction can be completed only by password, and there is a risk that the funds in the card will be stolen. In contrast, the all-round security technology system of chip card can effectively prevent such risks.
