Abstract: The invention provides an entrusted-authorization system and an entrusted-authorization method. The entrusted-authorization system comprises an accounting system, a switch module and an entrusted-authorization module, wherein the entrusted-authorization module stores entrusted-authorization parameters determined by the accounting system, the switch module is connected with the accounting system and the entrusted-authorization module for transmitting transaction request messages from the client terminal to the entrusted-authorization module for processing in case that the accounting system is unavailable, wherein the entrusted-authorization module verifies the transaction request messages according to the entrusted-authorization parameters; otherwise, the messages are sent to the accounting system for processing. The transaction request messages comprise financial account information, financial institution information, transaction-initiation institution information and transaction amount.
