Hello, I am using Agricultural Bank of China to pay for my sister’s college entrance examination online, and I am using K treasure. At the end, it always prompts, 592302, the signature verification of the transaction request message submitted by the merchant failed.

The main reason is that too many people are using it and the system is overloaded. Payment will be solved when there are fewer people. There are three reasons: 1. It is necessary to download the Tenpay security certificate; 2. It is because the payment cannot be made even after downloading the security certificate; 3. It is still possible to pay without downloading the security certificate before, but at this time the payment cannot be made.

Purpose of double signature

In the electronic payment system of e-commerce, there is the transmission of transaction information between customers, merchants and banks, including the transaction information that can only be seen by the merchant. order information, and payment information that can only be seen by the bank. Because the payment information that the bank needs to know is passed to the bank by the customer through the merchant.

The purpose of double signature is that during the transaction process, when the customer transfers the order information and payment information to the merchant, the order information and payment information are isolated from each other. The merchant can only see the order information but not the order information. Payment information is transferred to the bank unchanged.

And merchants and banks can verify the consistency of order information and payment information to determine whether the order information and payment information have been modified during the transmission process.
