Completing the reversal transaction means that the entry institution has completed the reversal remedial measures. In order to ensure the interests of users, financial institutions send a request to the host again, requesting to cancel the transaction process. There are generally two forms of reverse transaction, one is real-time reverse transaction, and the other is batch reverse transaction, which can effectively avoid the misoperation of the banking system and thus avoid the loss of customers.

Introduction of reversal transaction

Reverse transaction is a common remedy for financial institutions, and it is a remedy taken when the system thinks that the transaction may fail. When a transaction is marked as successful at the terminal, but the accounting transaction package sent to the host does not receive a response, the financial institution can take corresponding measures.

Abuse of automatic correction will lead to confusion of accounts. Therefore, the automatic reversal mechanism can only be adopted when one party's bookkeeping returns overtime, the bank can't determine its bookkeeping result, and there is the possibility of unilateral bookkeeping.

Automatic batch offset means that when one party returns from overtime, the system does not offset immediately, but only records some keywords in this transaction in a specific database or file, and the centralized party completes automatic offset at a specific time.
