Webinar: things you need to know about developing applications that use barcode scanning (but nobody told you!)

Overview: We often hear from manufacturers, wholesalers, distributors, retailers, hospitals and other end users that their software can’t scan barcodes. This is often due to a poor understanding of how barcodes work, what useful data they contain and how best to 'unpack' that data.

GS1 standard barcodes are structured in a way to allow systems to read as much or as little data as required.

This webinar is aimed at providing useful information that software developers need to be aware of to avoid the common pitfalls to enable efficient processing of contained data, and to avoid system crashes caused by scanning previously unseen barcodes.

The aim of this briefing is to ensure that your systems are future proofed, scaleable and robust when presented with any of the wide array of standard barcodes (GS1/EAN-13, DataBar, ITF14, GS1/EAN-128, Data matrix, QRCode, etc).

The webinar will also cover the different barcode types, some advice on barcode scanner configurations, use of Function 1 character, parsing a barcode and common errors (truncating fixed length fields, invalid check digit on GTIN, omitting function 1 character, invalid date formats and invalid weight formats).
