The "resolver" component of the Digital Link enables a single barcode to point to various data sources depending on the application reading the symbol. Without a "resolver the link encoded within a barcode can only point to a single web address. Using a "resolver", brands can direct different scans of the same barcode to the most appropriate final destination. For example, a product can have a single QR code on the packaging, but a scan with a “warehouse application” will lead to an entirely different end URL compared to a scan with a “consumer application”.
