"In the past, when using credit cards for consumption, some bank staff said that the installment payment was' interest free 'and' zero interest rate '. It was later discovered that the installment payment required a handling fee, which was no lower than the interest rate." Many consumers have had such experience. In the future, the phenomenon of opaque credit card interest rates and induced installment will be further standardized. The CBRC recently issued the Notice on Further Promoting the Standardized and Healthy Development of Credit Card Business, which requires to comprehensively strengthen the standardized management of credit card installment business. A bank shall uniformly adopt the form of interest when showing its clients the cost of using funds collected by installment business. At the same time, the bank is required to disclose the liability for breach of contract in a concise and understandable way when handling the credit card installment business with the customer, and the customer shall confirm and know. The relevant person in charge of the Bank Card Professional Committee of the China Banking Association believes that this will help consumers understand the interest cost and potential risks more clearly and use the card openly. "Credit cards should return to the original intention of" finance for the people "by adhering to the principle of" payment for the people "and strengthening the protection of consumers' rights and interests." Wang Bo, general manager of China Merchants Bank Credit Card Center, said that for consumers, they should also enhance their financial literacy, pay attention to preventing relevant risks and use credit cards rationally. The relevant responsible person of Shanghai Banking and Insurance Regulatory Bureau reminded consumers that credit cards should be handled through official websites and other formal channels. Pay attention to protecting bank card number, password, SMS verification code and other important information. When shopping online, do not click on unknown links at will, and do not enter credit card information on unknown websites. In case of credit card theft, the issuing bank shall be informed immediately. Experts suggest that rational borrowing and appropriate consumption are the basis for safe use of credit cards. Consumers should also carefully read the credit card customer agreement and carefully check relevant services. (Liu Xinshe)
