# Barcode Scan Information

When the STRwrench works with a source batch configured with Identifier Method set to Strings, the wrench's EHMI provides information on the scanned barcodes.

Every time a barcode is scanned, the following items are available on the EHMI:

- Scanned string.

- OK / NOK: if the scanned barcode is recognized as one of the identifier strings included in the source batch, the word OK is displayed. If it is not recognized, the word NOK is displayed.

- Scans counter: if more than one identifier string is included in the batch source, a counter keeps track of the scanned barcodes over the total amount of identifier strings.
