A person opens a banking application on their smartphone. They align the camera over the front of the check, capture the image, then repeat for the back side. With a tap, they submit the deposit request.
The screen responds with a confirmation notice. The action of depositing has occurred.
In the hours that follow, the account holder views their balance through the app or a computer. The figure remains as it was before the deposit submission. No increase appears.
Days pass with regular checks. The balance stays steady, showing no sign of the submitted check. The account appears unaltered during this time.
Eventually, after several business days, the balance updates. The added amount from the check now displays clearly in the account overview, visible upon refresh.
The interval reveals latency: the depositing action complete, yet the outcome absent from view until later.
