# Barcode is recognized as wrong

Cause | Solution
--- | ---
The user scans the barcode from a wrong part. | Make sure the user is provided with correct parts and that the parts have the correct barcode.
The barcode contains invalid characters. | Barcodes must contain only ASCII characters. Make sure there are no unusable characters in the barcodes that you scan.
The barcode terminator is not set. | Specify the barcode terminator in the scanner's settings. Smart AMS uses <LF> (line feed) only. <CR> (carriage return) is not used.
The barcode is malformed. | Make sure the barcode complies with the rules of your particular system. For example, all EAN-13 barcodes must contain 13 digits.
