Rescan
On the Self Checkout POS, customers scan items by themselves. Therefore, a check as to whether all items have been scanned correctly must be performed from time to time. This check can be a partial or a full rescan.

Full Rescan
If a full rescan is requested, the whole contents of the customer's basket must entered again by a member of staff. It is checked:
- whether an item was also scanned by the customer
- whether items were scanned too often by the customer
In either of these cases, the full rescan was not successful. The customer receives an additional receipt which displays the differences.


If the items in the customer's basket were scanned without differences, the full rescan was successful. The customer receives an additional receipt which indicates the successful rescan.
Partial Rescan
If a partial rescan is requested, only some random sample items from the customer's basket have to be rescanned. The number of random sample items is given.

If one of these random samples is missing, a full rescan must be carried out and the full rescan function is called immediately.
If the number of random sample items exceeds the number of items in the customer's basket, you can end the partial rescan with the corresponding button. In this case, the full rescan function is also called.
