Verification Queue
Verification queue is a repository where transactions awaiting verification are stored. A verification queue can contain transactions of current date or later. It should be noted that a past-dated transaction cannot be entered into the system and if the queue has value dated transaction(s) prior to the current date, it usually means there is something wrong with your application and you need help.
A future dated transaction is allowed and stored in the verification queue. However, you can verify future dated transaction in the future only, when the current date becomes the future value date.
