During scanning images go through our Optical Verification System ("OVS") which attempts to read the amounts on the images. If the images cannot be scanned, the items in question will go to our Key & Balance team to manually pull the image and key in the amount. If the image does not pass the initial OVS described above, then the scanned Deposit Amount will not match the control Deposit Amount. It is OK to close a Batch in this state, and you must close it in order for the Key & Balance team to adjust the total.
