Is there any error handling technique for unreadable barcodes?

On scanning barcodes through Appian mobile app barcode reader, certain barcodes are unreadable and hence cannot be scanned. The barcode reader doesnot thrown any TIMEOUT ERROR. Instead the barcode reader works like a mobile phone camera which hibernates after some time instead of throwing timeout error for unreadable barcodes. Anyone suggest a way to handle unreadable barcode errors.
