# WedgeScanner

Reads scanns from a wedge barcode scanner and will trigger the [OnScan](/wiki/client-api-reference/events/onscan.md)event.

The minimum length for a scan result (including prefix and suffix chars) is 5 characters. That means: A scanner with prefix and suffix chars of '#' can scan a barcode, that is at least 3 characters long. A scanner without a prefix and suffix char will scan a barcode that is 5 or more characters long. In case you need to scan a shorter barcode, you need to add prefix or suffix characters in your scanner settings
