Deprecation warning
Please note that this is outdated documentation for an older release of the Scandit Barcode Scanner SDK.
We are deprecating the 5.x API on all platforms (except Linux). Release 5.19 in April 2021 will be our final. Applications running 5.x will continue to work, and we will continue to release critical bug fixes and security patches only, for one year. We encourage you to migrate to 6.x and take advantage of our latest / advanced features and improved performance.
You'll find the updated documentation at: Data Capture SDK Documentation for React Native

Member Data Documentation
◆ enabled
boolean enabled |
Enables/disables decoding of dark codes on bright background only.
If color- inverted (bright on dark) codes for this symbology are required, enable them through the colorInvertedEnabled property. By default decoding of all symbologies is disabled.
It is advised to only enable symbologies that are required by the application as every enabled symbology adds processing overhead.
◆ colorInvertedEnabled
boolean colorInvertedEnabled |
Enables/disables decoding of bright codes on dark background only.
By default color-inverted decoding of all symbologies is disabled.
It is advised to only enable symbologies that are required by the application as every enabled symbology adds processing overhead.
◆ extensions
String [] extensions |
An array of all active custom extensions for the symbology.
Extensions are custom features that are only supported by a small number of symbologies. For a list of supported extensions, consult .
◆ checksums
Checksum [] checksums |
Array of additional checksums for this symbology.
When a barcode has been decoded, the checksums contained are evaluated in addition to any mandatory checksum defined by the symbology specification. If any of the checksums matches, the code is returned as recognized, otherwise it is discarded.
◆ activeSymbolCounts
int [] activeSymbolCounts |
Array containing the length of barcodes to be decoded for this symbology.
Change this property to enable decoding of long codes which can not be decoded with the default settings, or to optimize decoder performance for codes of certain lengths. This is useful when it is known that the application only requires scanning of particular barcode lengths.
The mapping from characters to symbols is symbology-specific. For some symbologies, the start and end characters are included, others include checksums characters in the symbol counts.
The active symbol count setting is ignored for fixed-size barcodes (the EAN and UPC family of codes) as well as 2d codes. For other symbologies, see Calculating symbol counts for variable-length symbologies.
