Credit Count

The default 'QR Code - Read from Document' flow action parameters are detailed below:

• File Type: Select the type of file provided

Advanced Parameters

The advanced 'QR Code - Read from Document' flow action parameters are detailed below:

• Confidence:
  • High - Confidence in recognition, where there are no errors in read codetext or fake recognitions.
  • Medium - Confidence in recognition of mostly 1D barcodes, where there may be no weak checksum or no checksum present. The QR code could contain misrecognitions in the codetext, or even fake recognitions, if it is low.
  • Low - Confidence in recognition of a QR code where codetext was not recognized correctly or barcode was detected as possibly fake.
• Quality: Controls barcode detection quality. Higher settings may improve recognition but reduce performance.
  • Low - Optimized for faster detection of clear, high-quality barcodes. May be less effective with damaged, distorted, or low-quality barcodes.
  • Normal - Balanced detection quality and performance. Suitable for most common barcode images.
  • High - Improves recognition of lower-quality, damaged, distorted, or harder-to-detect barcodes, with some performance impact.
  • Max - Uses the most thorough detection settings for difficult or poor-quality barcodes. Provides the highest recognition capability but may significantly reduce performance.
• End Page - Set the page number to end reading on
• Remove Control Characters - Set whether recognised control characters should be removed
