    Public Property Confidence As Long
    Return Type
    A long value which represents the confidence of the barcode.
    Remarks

    All barcode confidence values begin at 100.

    • 1D barcodes - Confidence values are decreased as the widths of the bars vary over the barcode.
    • 2D barcodes - Confidence values decrease based on the amount of error correction used in decoding the barcode.
    • Barcodes which use checksums - If a checksum error is detected, the confidence is set to 50.

    Confidence values less than 30 are considered unreadable and any data returned is not considered reliable.
