This sample repository illustrates how to parse a raw textual payload containing group separators into individual GS1 Application Identifiers.
When used with the STRICH Barcode Scanning SDK, use the symbologyIdentifier property to determine if a barcode contains GS1 data or not.
The actual parsing is done by BarcodeParser or GS1 DigitalLinkToolkit.js, the sample demonstrates usage of both libraries.
