Interpretation of the credit card loss protection regulations of major banks. Many bank credit card centers have stated that when cardholders find that their cards have been lost or card funds have been misappropriated, it is best to report the loss to the bank first. After the loss report takes effect, the cardholder No longer responsible for losses caused by counterfeiting or misappropriation of lost cards. The difference is that if the card is swiped before being reported as lost, the cardholder will face a different fate. If there is lost card protection, the bank will verify and settle the claim through the insurance company, and the stolen funds will be borne by the insurance company. Each bank has different time limits for reporting losses. Most banks provide coverage within 48 hours if the card is lost, while a few banks provide coverage within 72 hours. Bank of Communications, China Merchants Bank, China Guangfa, China Everbright, Hua Xia, Beijing, Ping An, BEA China, etc. provide lost card protection. For credit cards that do not provide loss protection and are used for purchases with signatures, if they are stolen before being reported as lost, most banks require cardholders to fill in relevant information and report the case themselves. The banks will assist cardholders to negotiate with merchants to resolve the problem of capital losses. However, the bank also emphasized that if the negotiations are unsuccessful, the loss should be borne by the cardholder. Banks such as ICBC, Agricultural Bank of China, Bank of China, China Construction Bank, Shanghai Pudong Development Bank, CITIC, Minsheng and Shenzhen Development Bank do not provide loss card protection.
