security issue
Due to the convenience and rapidity of using credit cards, coupled with the rapid development of science and technology, the security problems faced by credit cards are becoming more and more serious, and major international credit card groups and global card-issuing financial institutions are facing severe challenges. The security problems of credit cards are mainly divided into the following five aspects:
Credit card: criminals or criminal groups use forged or invalid cards (expired/lost/invalid/damaged tapes, etc.). ) pretending to be a real card, directly deceiving merchants or card issuers.
Cardholder: improper card storage/handling (expired/tape-invalid credit cards are not destroyed, or they are not immediately invalid after being lost, etc. ), and personal identity information is inadvertently stolen or defrauded. In order to avoid such problems, citizens should not easily provide personal identification information, and it is best not to entrust others to handle credit cards.
Consumer merchants: the service personnel swindle the cardholder in the process of consumption, or steal his credit card information to other merchants for consumption. This situation can happen whether it is a physical business or a network virtual business.
Issuer: The computer system has been maliciously invaded, stealing the basic/transaction information of customers. There are also unscrupulous employees who steal from the house, or the evil inside the house.
Trading system and mechanism: as long as it is formulated or handled by human beings, human errors and omissions will inevitably occur; No matter how rigorous the trading mechanism is, with the world-class trading system from confirmation to settlement, it is still possible to be invaded, and the so-called "invasion" is actually divided into levels.
