A pin number security system for debit card and credit card: when creating an account in a bank or a credit card company, the client will provide his or her mobile phone or wire telephone number or email address, the pin number of the debit card or the credit card can only be used once, and immediately, a new pin number will be sent to the client as a text message or email or via telephone transmission through the mobile phone or wire telephone or email provided by the client in his or her registration records at the bank or the credit card company. The frequent change of pin number for a client's debit card and credit card greatly improves the security level of such card, and reduces the opportunity of causing inconveniences to the client. And as no material modifications are needed for the existing pin number system for debit card and credit card, the entire system does not increase the operating costs for banks and credit card companies.
