Understanding Different Link Types in 2D Barcodes 

Link Types enable different scans of the same 2D Barcode to route to distinct destinations. When a retailer scans a 2D Barcode at the point of sale, it functions akin to a standard UPC or EAN barcode, revealing the product's GTIN number and price. However, when the same 2D Barcode is scanned using a smartphone camera or app, it can seamlessly connect the user to extensive digital product details.

This functionality is facilitated through Link Types, which can be customized to suit specific needs.

What are the most common Link Types?

Some of the most common Link Types are below (a full list is at the bottom of this page).
