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.
